Dear list,
n00b question, but still can't find any easy answer.
Here is a df:
df-data.frame(cbind(x=c(AA,BB,CC,AA),y=1:4))
df
x y
1 AA 1
2 BB 2
3 CC 3
4 AA 4
I want to modify this df this way :
if df$x==AA then df$y=df$y*10
if df$x==BB then df$y=df$y*25
and so on with other

# No, your y is a factor
str(df)
'data.frame': 4 obs. of 2 variables:
$ x: Factor w/ 3
