Dear Rui,
Thnak you very much: this works exactly as I requested, but the merged
vetor (res) order the variables by alphabetical order rather than by the
factors I indicated during
Dear all,
I have obtained the averages (means) and standard deviations (SD) of
different variable using the aggregate function, which I have found very
useful for these kind of computation.
However I would like to calculate the lower and upper ends of the
data (that is mean - SD and mean + SD)
Hello,
Maybe something like the following.
res - merge(AVG, SD, by = stimulation)
names(res)[2:3] - c(AVG, SD)
res$lower - res$AVG - res$SD
res$upper - res$AVG + res$SD
res
Hope this helps,
