Apologies if this is a dumb question, but have been searching and experimenting for a while without success. I have a dataframe with dates and returns in it (2 columns) and want to create a new dataframe with only positive returns in it.

Thanks in advance

(An example would be nice.)

Would the following work for you?

# assume `x' is your data.frame
# with `return' your column of returns
pos.x <- x[x$return > 0, ]

HTH,
