I cannot remember how to install a package not available in the current version of R (If you were wondering, this lack of cognition is due to a severe illness). I need to install alr3, created under version 3.03 (I believe). I cannot find a compatible version of it either.
Warning in install.packages :
package ‘alr3’ is not available for this version of R
I need this package to complete my project. Any help would be much appreciated.
