Hello everyone...
Today I tried to install RStata but I had the following output when I used install.packages('RStata'):
Warning in install.packages :
dependency ‘foreign’ is not available
trying URL 'https://cran.rstudio.com/src/contrib/RStata_1.1.1.tar.gz'
Content type 'application/x-gzip' length 6460 bytes

ERROR: dependency ‘foreign’ is not available for package ‘RStata’
* removing ‘/home/Axo/anaconda3/envs/rstudio/lib/R/library/RStata’
Warning in install.packages :
installation of package ‘RStata’ had non-zero exit status

The downloaded source packages are in
‘/tmp/Rtmpj8Bmgw/downloaded_packages’
Updating HTML index of packages in '.Library'
Making 'packages.html' ... done

Next to I typed install.packages('https://cran.rstudio.com/src/contrib/RStata_1.1.1.tar.gz')and so:
Warning in install.packages :
package ‘https://cran.rstudio.com/src/contrib/RStata_1.1.1.tar.gz’ is not available (for R version 3.6.1)

By the way, I'm using Anaconda and RStudio.
