无法在RStudio中安装Swirl课程

Question

I'm trying to install Swirl courses in RStudio on 64-bit Ubuntu 15.10, and I am running across an error. I tried to install a course using the command install_from_swirl("Data_Analysis") , but the system either just hangs (R needs to be interrupted to recover from this), or I get the following error:

Error in unzip(path, list = TRUE) : 
  zip file '/home/xxxxx/R/x86_64-pc-linux-gnu-library/3.2/swirl/Courses
 /temp.zip' cannot be opened

The temp.zip doesn't appear to be a zip archive (I'm unable to open in on the command line).

Answer 1

You actually helped me with the command! I used

    install_course("Data Analysis")

but it didn't work, then I used

    install_from_swirl("Data_Analysis")

and it worked! Try running the swirl library first:

    library("swirl")
    install_from_swirl("Data_Analysis")    # CASE SENSITIVE!
    swirl()

I wish you luck!
