Swirl: error of loading swirl

[HengshuoLiu]

Hi

I have installed swirl but when I load it, I get the following message

install.packages("swirl")
trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.3/swirl_2.4.2.zip'
Content type 'application/zip' length 212141 bytes (207 KB)
downloaded 207 KB

package ‘swirl’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in
C:\Users\Hengshuo\AppData\Local\Temp\RtmpklUL8A\downloaded_packages

library(swirl)
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
there is no package called ‘stringi’
Error: package or namespace load failed for ‘swirl’

How can I fix this error?

Thank you very much for the help.

Have you tried installing stringi on its own?

@kshitij1995 Have you tried installing bitops on its own?

Thanks Sean!

I did install bitops on my own today after receiving your email.
Restarted and working now. But getting following errors. Do I need to
change the working directory to something while working with swirl.

urban <- read_csv("datapath/urban.csv.gz")Error: 'datapath/urban.csv.gz' does not exist in current working directory ('C:/Users/Oktoer Naseim/Desktop').> urban <- read_csv("urban.csv.gz")Error: 'urban.csv.gz' does not exist in current working directory ('C:/Users/Oktoer Naseim/Desktop')

Appreciate any help.

I was having the same problem, and i did the following:
Go to (C:) and searched for the R files. Once you've clicked the R file, look for "Courses" and there will have a YAML archive. Then, you can open it with R Studio.

Thanks for your response.
I uninstalled and then reinstalled R and R Studio. Since then I did not see any issues.

I'll try your suggestion, if I run into same issues.
Thanks again.

Sean, shouldn't the missing packages be installed according to this code?

[seankross]

@elinw Of course it should, but it occasionally it doesn't work.

Actually when you install and download libraries for swirl in R console in windows7, it is not able to extract and transfer from temp folder to required folder. so you have to manually move and extract it from there to the required folder and do not forget to move the required dependencies folder also. In my case i have to move from C:\Users\Usrename\AppData\Local\Temp\Rtmp69bYd2\downloaded_packages to C:\Users\Usrename\Documents\R\win-library\3.4
