I finally could download and install the swirl package but when I want
to load it using library (swirl) it gives the following message
package ?swirl? successfully unpacked and MD5 sums checked
The downloaded binary packages are in
C:\Users\Emdad
notebook\AppData\Local\Temp\RtmpEJyZTB\downloaded_packages> library(swirl)
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck =
vI[[j]]) :
there is no package called ?R6?
Error: package or namespace load failed for ?swirl?
what should I do now?

Hi
I cant install swirl as there is no packages in the CRAN, why?
following is the message
ERROR: dependency ?testthat? is not available for package ?swirl?
* removing ?/home/kazem/R/x86_64-pc-linux-gnu-library/3.0/swirl?
Warning in install.packages :
installation of package ?swirl? had non-zero exit status
The downloaded source packages are in
?/tmp/RtmpCaSEgn/downloaded_packages?> library(swirl)
its annoying isn't?
