[R] Question

[S. Mahmoud Nasrollahi]

Dear colleague
I have got a problem during working with some package in R and in
spite of trying with R help, internet and any other resources I could
not succeed. Indeed when I what to install some function like bwplot,
boxplot,  xyplot I receive this sort of messages:
 Warning in install.packages :
  package ‘xyplot’ is not available (for R version 3.5.2)
Do you know how I can solve that?
