I was trying to install.packages("rattle")
but it shows this :
Installing package into ‘/home/shahin/R/x86_64-pc-linux-gnu-library/3.4’
(as ‘lib’ is unspecified)
Warning in install.packages :
package ‘rattle’ is not available (for R version 3.4.4)
I am in ubuntu 18.04. I also tried to install RGtk2 that also shows error. How can i install rattle?
rattle
requires R version 3.5.0 or higher.
Update R to the latest version, then you'll be able to install it.
