install.packages("testthat") should fix this error.

I confirm the same problem on Ubuntu Linux. The suggested solution didn't work.

Thanks for looking into this problem Sean. I'm getting the same issue as well for a Coursera class and found this thread while searching for a solution. If you need any further details, I've subscribed to notifications here and can reproduce it currently.

Temporary workaround:
install.packages("ghit")
library(ghit)
install_github("swirldev/swirl[stable]")
library(swirl)
swirl()
I'm working on a permanent solution that will be released as quickly as possible.

Also verified this work-around corrected it for me on Ubuntu 15.10. Thanks for getting it out there so fast!

Please download the latest version of swirl with install.packages("swirl"). This should resolve the issue. Make sure your installed version of swirl is 2.4.1 or later.

Dear @seankross thanks for your effort solving this problem and for your great contribution to spread the R Language learning. Now my swirl installation is working.

I'm having the same issue in the Functions tutorial:
| The last R expression to be evaluated in a function will become the return value of that function. We want this function to take one
| argument, x, and return x without modifying it. Delete the pound sign so that x is returned without any modification. Make sure to save
| your script before you type submit().
Error in editor(file = file, title = title) :
argument "name" is missing, with no default
| Leaving swirl now. Type swirl() to resume.
I tried the "testthat" package, restarting RStudio. and reinstalling swirl.
Also ran the temp fix:
install.packages("ghit")
library(ghit)
install_github("swirldev/swirl[stable]")
library(swirl)
swirl()
