Hello,
And here are three more ways. I will put the data, corrected in Bert's
post, in a data.frame.
R <- c(1,8,3,6,7,2,3,7,2,3,3,4,3,7,3)
Day <- c(1,1,1,1,1,2,2,2,2,2,3,3,3,3,3)
Freq <- paste0("a", rep(1:5,3))
df1 <- data.frame(R, Day, Freq)
# Base R, as for the function, see Bert's post

Well, first of all, your example is messed up. You missed the "c" in front
of the ( in Freq <-; and all of the Freq entries need to be enclosed in
quotes for proper syntax. A simpler way to do it is just to use paste() and
rep():
Freq <- paste0("a", rep(1:5,3))
(If you are not familiar with such "
I am having problems making a correlation/association between two variables
by a factor.
In the case below, I need to know the correlation between R and Day at each
frequency (a1-a5). Each frequency would have a corresponding correlation
between R and day.
I have found a lm function that is simil
