One way to end up with a corrupted workspace is to save it with a

Dear All,
I am new to R. I have a 2 column data frame with more than ten thousand
rows. Something like below. I want to add up all duplicated items, e.g. the

do that?? Thanks for help !
gene value

Hi:
There are many ways to do this sort of thing in R; one way is (naming
your example data frame d)
aggregate(value ~ gene, data = d, FUN = sum)
gene value
1 aa74
2 bb10
3 cc 9
4 dd 100
5 ee55
This code line works for R-2.11.0 and later.
