I got an identical error message when instead of combining two data frames (a,b) with a method such as: a <- cbind.data.frame(a,b) I embedded a data.frame in another, e.g., a$b <- b In the latter example, I have a column (a$b) that consists of a data frame onto itself, which write.table apparently can't handle.
