unable to install data explorer package

i want to install data explorer package in R and RTools . i keep getting following error repeatedly

https://cran.rstudio.com/bin/windows/Rtools/
Installing package into ‘C:/Users/MY/Documents/R/win-library/3.6’
(as ‘lib’ is unspecified)
Warning in install.packages :
package ‘Rtools’ is not available (for R version 3.6.1)

please help

Rtools is not an R package, it is a separate software, you have to download it and install it in your system, not in R.
