I have 100+ .csv files which have the basic format:
> test
X Substance1 Substance2 Substance3 Substance4 Substance5
1 Time1 10 0 0 0 0
2 Time2 9 5 0 0 0
3 Time3 8 10 1 0 0
4 Time4 7 20 2 1 0
5 Time5 6 25 3 2 1
6 Time6 5 30 4 2 2
7 Time7 4 25 5 3 3
8 Time8 3 20 6 3 4
9 Time9 2 15 5 3 5
10 Time10 1 10 4 4 6
Each table is of exactly the same dimensions. After reading each of the
100+ .csv files into R, I want determine the mean and SD of each and every
cell. That is to ask, I to calculate the mean and SD for (Time1,Substance1)
and every other cell from each of the 100+ .csv files.
I imagine this is a fairly basic question, but my search has been
unsuccessful.
Thanks in advance,
ECN
