[R-sig-Geo] merge 2 txt file

[Ashton Shortridge]

Hi Ale,

When you say merge, do you mean you want to append one onto the other, or you 
really want to merge elements that have common x and y values?

If it's the first case, then I'd probably read both in with read.table() and 
then rbind them:
dat1 <- read.table("file1.txt")
dat2 <- read.table("file2.txt")
dat3 <- rbind(dat1,dat2)

If it's the second, I can't help much. Did you try it? Did that work? If you 
can't tell (if, say, the text files are really big) then make two small test 
files and try that.
