Hi, Try this:
DF1 <- data.frame(var1 = letters[1:5], x = rnorm(5), y =2) DF2 <- data.frame(var1 = letters[3:7], x = rnorm(5), y=3) DF3 <- data.frame(var1 = letters[6:10], x = rnorm(5), y=0) # ... DF10 if you wish ( result <- merge_all(list(DF1, DF2, DF3) )) save( result, file ="merged.rda")
I didn't know of this function, thanks. Similar solutions using base functions were proposed recently on http://wiki.r-project.org/rwiki/doku.php?id=tips:data-frames:merge and i've now added this for reference.

Hi R users, Can anyone share some example code using merge_all (from the reshape package) to merge 10 data frames into 1 file.
