Swirl: Unable to Install Swril

I'm receiving the exact same error

Try the following:

install.packages("swirl", repos="http://cran.rstudio.com/", dependencies=TRUE)

install.packages("swirl", repos="http://cran.rstudio.com/", dependencies=TRUE)
Warning: unable to access index for repository http://cran.rstudio.com/src/contrib
Warning: unable to access index for repository http://cran.rstudio.com/bin/windows/contrib/3.2
Warning message:
package ‘swirl’ is not available (for R version 3.2.1)

Seems like this also not working.

See #326 and let me know if that works.

sorry to say, even this is not working!

Try choosing a CRAN mirror near you with:

chooseCRANmirror()

and then try:

install.packages("swirl")

Hi, As suggested I used the following : chooseCRANmirror() followed by install.packages("swirl"). 2 of the dependencies viz memoise and stringi were downloaded successfully. All other dependencies failed to download

also installing the dependencies ‘memoise’, ‘stringi’, ‘magrittr’, ‘crayon’, ‘jsonlite’, ‘mime’, ‘curl’, ‘R6’, ‘bitops’, ‘stringr’, ‘testthat’, ‘httr’, ‘yaml’, ‘RCurl’, ‘digest’

I retried and could successfully install swirl. Thanks for the posts.

This is the error I keep getting while trying to install swirl. I referred and tried what was told in posts #325, #326. Please help

@jinny20 what CRAN mirror are you using?

I had a problem while trying to install the swirl package.

install.packages("swirl")

once this command is executed you are required to choose a CRAN mirror. Problem that I faced was: I chose my CRAN mirror for USA(CA). As soon as I did that I got an error that the swirl package for

"R version 3.2.3 is not available"

In order to install the swirl package I had to change my CRAN mirror which can be done using

chooseCRANmirror()

once you execute this function you can choose a different CRAN mirror. I chose USA(TX) and then executed

install.packages("swirl")

and everything worked fine after.

Thanks @seankross

thanks @seankross ..choosing cran worked for me!

Hey @seankross , I'm from India and I've been trying install swirl for over 12 hours now. I'm new to this so I might be making a stupid mistake. Here's what pops up when i try to install swirl-

@njnlol What R version are using to install swirl 32 or 64-bit?
I had the same problem and I realized that I was using a 32-bit version. I switch to 64-bit version in RStudio and worked without any trouble.

Hi,

I am new to R. Can anyone help me out with the below error I am getting while loading Swril?

I am currently using Windows 10, 64 Bit with R-3.5 64 bit version.

@Yagyika I think it is "swirl" and not "swril"
