The optimal way of doing it depends on how you want to use the result. An
easy way has been recommended - if you have
boo <- list(first=data.frame(a=1:5, b=2:6), second=data.frame(a=6:10,
b=7:11))
.. then
sink("boo.txt")
boo # or: print(boo)
sink()
... will put it all in the same file, the same way it would ordinarily
appear on the screen . But this is not a csv file (Comma Separated Values),
and it's not easily usable by other software (try re-reading it to R). I
think a better way for most purposes would be to make it a big table and add
an extra variable (say, GROUP). To do it in one go you might use something
like
boo <- mapply(function(x,y) within(x, GROUP <- y), boo, names(boo),
SIMPLIFY=FALSE)
... then put the different pieces together using something like
do.call(rbind, boo)
# resulting in something like this:
a b GROUP
first.1 1 2 first
first.2 2 3 first
first.3 3 4 first
first.4 4 5 first
first.5 5 6 first
second.1 6 7 second
second.2 7 8 second
second.3 8 9 second
second.4 9 10 second
second.5 10 11 second
... and the result is what you can write to a csv file and later easily
re-read using any software
write.csv(do.call(rbind, boo), "boo.csv")
