Swirl: Swirl won't load in R Studio

[bwkeim]

Hello,
I downloaded swirl using install.packages in R-Studio and when I type library(swirl) I receive the following error message:

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :
there is no package called ‘evaluate’
Error: package or namespace load failed for ‘swirl’

My session info is:

R version 3.0.2 (2013-09-25)

locale:

Hopefully you can help,

Please try the following and let us know if it solves your problem:

install.packages("swirl", dependencies=TRUE)
library(swirl)

[bwkeim]

Hi,
Unfortunately that didn't work :-(

[ncarchedi]

We can be more helpful if you copy and paste your exact input and output, so we can see what's happening. Try this:

install.packages("evaluate")
library(swirl)

[WilCrofter]

The diagnostic says it's trying to load package 'evaluate' which it can't find locally. Installing it may help.

Package evaluate is maintained by Yihui Xie, and is a dependency of knitr. Most of us probably have knitr, hence evaluate, installed. I can't see why it should be a dependency of swirl, however.

[ncarchedi]

evaluate is also a dependency of testthat, which swirl imports. Installing evaluate directly should help. See https://github.com/hadley/ggplot2/issues/540.

[bwkeim]

Hi Nick,
The evaluate install did the trick.
Many thanks,
Bernie

[justincherveny]

I did both of ncarchedi's recommendations

install.packages("evaluate")
library(swirl)

and

install.packages("swirl", dependencies=TRUE)
library(swirl)

and I still get the same error:

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :
there is no package called ‘yaml’
Error: package or namespace load failed for ‘swirl’

Anything else I should try?

Just responded here: https://github.com/swirldev/swirl/issues/190

[FKrauss]

Saw the same thing here... the way was to install each package that it depended on individually. I got the following and it worked (meaning: i got the swirl welcome message):
install.packages("evaluate")
install.packages("codetools")
install.packages("testthat")
install.packages("swirl")

[ncarchedi]

In general, install.packages() should handle package dependencies, but you can try adding the argument dependencies = TRUE in the future.

After numerous attempts installing 'swirl' getting a nonzero on install (which means an error)
I already had installed 'Ilibcurl4-openssl-dev' using apt
already had installed the packages inside R for 'evaluate', 'codetools' and
I tried installing 'testthat'
which gave this error package ‘testthat’ is not available (for R version 3.0.2)
The following fixed this problem for me (Linuxmint 17 which uses Ubuntu Trusty repos)
Installing 'r-cran-testthat' using apt

[svicente99]

I got stuck in these some points described above by peers.
I installed 'evaluate', "codetools"... I tried to install swirl with dependencies=TRUE. Nothing!!
Same error message:
ERROR: dependency ‘testthat’ is not available for package ‘swirl’
What's going on? Is it really possible to use "swirl" in Linux Mint 17 distro? I don't like to come back to Windows only to solve this part of R practices... Sad.

[WilCrofter]

Yes, it is really possible to use "swirl" in Linux Mint 17 distro. I do, for instance.

I'm not sure what's going on with your system, but people do have trouble with Hadley's packages (testthat) from time to time. Make sure all the imports and dependencies are intstalled.

[gngdhr]

Based on the requirements for testthat, testthat requires R 3.1.0 atleast and looks like you are using R 3.0.2. Can you consider upgrading R to 3.1+. The latest is 3.2.

Linux Mint 17 comes with R 3.0 by default. You will need to upgrade R to 3.2. You can follow the instructions provided here.

Hope this helps.

[massimolai80]

I had the same problem on Linux Mint 17.1 (Rebecca), using R 3.0.2, but I found a workaround.

For some reason, install.packages() could not handle the dependencies correctly (even with the dependencies=True option).

However, as reported by others, the installation works perfectly after installing the evaluate, codetools and testthat packages using apt or synaptic (both seem to handle the dependencies well... as usual):

sudo apt-get install r-cran-evaluate
sudo apt-get install r-cran-codetools
sudo apt-get install r-cran-testthat

I also had to run rstudio as superuser (for the installation directory to be writable)

sudo rstudio

And then, from the R interpreter,

install.packages("swirl")

[diegodondiego]

Hi, I also had the same problem. My SO is Ubuntu 14.04 LTS. I just followed the instructions from @massimolai80 and swirl is now working.

The only difference is that I think that is not necessary to run rstudio as sudo. I didn't need to do that.

[josephinegiaimo]

I said yes to installing on a personal library and now I have to pick an HTTPS CRAN mirror. Why?

[seankross]

Hi @josephinegiaimo,

What country are you located in? Your geographic location is usually a good indicator of what CRAN mirror you should use.

Please let me know if that works.

[KVSRPVARMA]

pls help me to come out of this error while installing swirl in R studio

[seankross]

@KVSRPVARMA Are you using an internet connection at work or school? There seems to be an issue with your connection.

Many thanks @ncarchedi . That worked for me

[jfdn]

Hi

I get the following message when I am trying to run swirl. Does any one have a solution for this?

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :
there is no package called ‘R6’
Error: package or namespace load failed for ‘swirl’

Thanks
Darun

[seankross]

Hi @jfdn,

What do you get as the result of sessionInfo()?

[jfdn]

Also when i try to load through packages i get;

library("swirl", lib.loc="\orunet/dfs/home05/jfdn/my documents/R/win-library/3.3")
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :
there is no package called ‘R6’
Error: package or namespace load failed for ‘swirl’

[seankross]

Hi @jfdn,

Are you using a computer that belongs to your workplace or school? What do you get as the result of sessionInfo() ?

[jfdn]

Hi @seankross
That is the problem I think, the computer belongs to my workplace.
I had someone look at it and came to the same conclusion. He changed something but i don´t now what.

this is what i get when I run, sessionInfo()

[seankross]

Are you still having the same issue after the change?

[jfdn]

Hi @seankross

No, it´s working fine right now.

Thank you for your time.

Darun

[SabriJamal]

I had the same problem where it constantly told me that swirl package does not exist when running library(swirl) after install.packages("swirl"). If you are running ubuntu 14.04 i can advise you that the following instructions worked

https://github.com/swirldev/swirl/wiki/Installing-swirl-on-Linux

Basically the problem (at least for me) was that the curl package which is used to download packages from the internet was not downloaded.

Hope it helps

Hello I am getting following error while installing swirl from library.

library(swirl)
Error in parse(n = -1, file = file, srcfile = NULL, keep.source = FALSE) :
1:1: unexpected $end
Error : unable to load R code in package ‘R6’
Error: package or namespace load failed for ‘swirl’

[HudsonShi]

System: win 10 64
R: 3.32
When I was installing swirl package

local({pkg <- select.list(sort(.packages(all.available = TRUE)),graphics=TRUE)

• if(nchar(pkg)) library(pkg, character.only=TRUE)})
  Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :
  there is no package called ‘bitops’
  Error: package or namespace load failed for ‘swirl’

How to fix it?

[seankross]

@tariqulhoda that's a really bizarre error, are you sure you have the latest version of R installed?

[tariqulhoda]

That's right Sean, I even reinstalled the programmer but the result give me the same. :(

R version 3.3.2 (2016-10-31) -- "Sincere Pumpkin Patch"
Copyright (C) 2016 The R Foundation for Statistical Computing
Platform: x86_64-w64-mingw32/x64 (64-bit) this is the version which i installed.

[seankross]

@tariqulhoda can you try install.packages("R6") on its own?

[ravivissa]

I am unable to use Swirl in R.

When I install Swirl --> it shows successfully unpacked. But when I call the library then following is the error

---

Error: package or namespace load failed for ‘swirl’ in FUN(X[[i]], ...):
no such symbol R_curl_BinaryData_new in package C:/Program Files/R/R-3.4.0/library/RCurl/libs/x64/RCurl.dll
In addition: Warning message:
package ‘swirl’ was built under R version 3.4.1

---

Any inputs please.

[Nidhitandon]

Try the following, might work -
install.packages("bitops")
library(swirl)

[ravivissa]

Thanks Nidhitandon for the response. I figured out that I had two R versions in my office laptop. R studio was downloading the packages in old version of R which is outdated(blocked by internal IT) so was unable to use the library when called. Well figured out the same after few hours of diagnosis with the support team. :-)
Thanks once again for the response

[MesyMacos]

I fixed my issue by updating the Swirl packages in RStudio. I hope this solves your issue.
