I tried to install Rtools from [https://cran.r-project.org/bin/windows/Rtools/index.html ]
downloaded the Rtools35.exe file and ran the installation for R version 3.5.3. I got the following codes of error
install.packages("Rtools")
Installing package into ‘C:/Users/harik/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)
Warning in install.packages :
package ‘Rtools’ is not available (as a binary package for R version 3.5.3)
Please, can someone help? Thanks
