Error loading a Swirl Course #572

After completing the R Basic Programming course, I wanted to do the Data Analysis course. I followed the procedure to install it, but it thrower up an error. Then I went ahead and installed the course master zip.

I then entered swirl() and proceeded to select the Data Analysis course, now it throws up this new error and exits.

I had a similar problem.

  1. install_from_swirl("Overview_of_Statistics",dev=FALSE,mirror="github") Course installed successfully!

  2. I tried to choose several lessons from the selection menu but got: Error in file(con, "r") : invalid 'description' argument | Leaving swirl now. Type swirl() to resume.
