R help - Jul 2009 - For loop for distinguishing negative numbers

Hi i am very new to R and I have been trying to change each individual piece
of data in a data set to 10 if it is below 0 and 5 if it is above 0. I know
this sounds very easy but i am struggling!!

see ?ifelse

you didn't specify what happens if a value is exactly zero in the dataset
and so i've just bundled it in with the negative case:

x <- rnorm(20, 0, 1)
y<-ifelse(x<=0, 10, 5)
