Expert R users, what's in your .Rprofile? [closed]

Answer 1

Make data.frames display somewhat like 'head', only without having to type 'head'

print.data.frame <- function(df) {
   if (nrow(df) > 10) {
      base::print.data.frame(head(df, 5))
      cat("----\n")
      base::print.data.frame(tail(df, 5))
   } else {
      base::print.data.frame(df)
   }
}
