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? -- S.
