Dear R help,
I have a data frame column in which I would like to replace some of the
numbers dependent on their value.
data frame = zz
AveExpr t P.Value FC
7.481964 7.323950 1.778503e-04 2.218760
7.585783 12.233056 6.679776e-06 2.155867
6.953215 6.996525 2.353705e-04 1.685733
7.647513 8.099859 9.512639e-05 1.674742
7.285446 7.558675 1.463732e-04 1.584071
6.405605 3.344031 1.276812e-02 1.541569
I would like to replace the values in column 'FC' which are >2 with their
squared value.
If I do this, however, I get a warning but it does the sum correctly.
Warning message:
number of items to replace is not a multiple of replacement length in: zz[,
4][zz[, 4] > 2] <- zz[, 4]^2
Is there a way to do this without the warning?
