No I didn't, I still use bash with the same ~/.bashrc.

Yes, there's no problems with that here either, nor with:
---<--------------------cut here---------------start------------------->---
$ cat <<EOF | r -
print(summary(read.csv("ds_060910_090528.csv", colClasses=c(rep("character",
2), "numeric", "character", rep("numeric", 2), rep("character", 4),
rep("numeric", 3), rep("logical", 4)))))

which only differs by list.files() with the problem code. But check
this:
---<--------------------cut here---------------start------------------->---
$ cat <<EOF | r -
print(summary(read.csv("ds_060910_090528.csv",

EOF

littler: Incomplete Line! Need more code!
---<--------------------cut here---------------end--------------------->---
which differs by the newline in read.csv() compared to above code. It
seems as if now the expression should be complete on the first line?
