functions in the base namespace can see objects in the utils namespace?

Again, please keep the list copied.
I think the documentation is clear, but if you still have doubts why

This is all in the R-admin manual. You may have to install rJava from the
sources.
And such questions belong on r-sig-mac: see the posting guide.

You did not show the error message you got from that
I hadn’t seen an error message because I hadn’t tried it yet. I was

An alternative to Jim's solution which seems to work and you may, or may not,
find less messy:
df - read.table(text=id yr val

b 1952 3
c 1952 4

df1 - df[order(df$id, df$yr),]
df1$valCS - unlist(by(df1$val,
