Dear List, somebody knows, if the following operation can be done in an easier way? The data rows which should be read into R look like that: 4547;1970.01.01 00:00-1970.01.01 01:00; noData Unitil now we are doing this procedure: 1.

I have data that looks like this: > df1 group id 1 red A 2 red B 3 red C 4 blue D 5 blue E 6 blue F I want a list of the groups containing vectors with the ids. I am avoiding subset(), as it is only recommended for interactive use. Here's what I have so far: df1 <- data.frame(group=c("red", "red", "red", "blue",
