DF <- data.frame(a=1:2, b=c("a","B"))
cat("header1\nheader2\n", file="filename.csv")
cat("header3\n", file="filename.csv", append=TRUE)
write.table(DF, file="filename.csv", append=TRUE)In S-Plus 6.2 and R 1.8.2, this produces the following:
header1 header2 header3 "a" "b" "1" 1 "a" "2" 2 "B"
hope this helps. spencer graves

I suppose one way to do it is to write the header info to the file first (e.g., through connections, or sink(), etc.), then do write.table(..., append=TRUE).

ncols 532 nrows 999 xllcorner 510465 yllcorner 4766375 cellsize 30 NODATA_value -9999
Thanks very much,
