Hi,
I have a really simple question.
I need to convert a data.frame with the following format
A 10
B 5
C 9
A 5
B 15
C 20
in this format
A 10 5
B 515
C 920
Thanks !!!

I know two ways to convert dates and time from on time zone to another but

You can try this:

selsing - grep(sing,f) #Select the files notaining the word sing

How those models compare with models with the form Y ~ s(X1) + s(X2)
