I have a dataframe with 3 columns. The first column stores an index. I would
like to calculate the mean of the numbers stored in each of the rest of the
columns.
So,
here is my data matrix:
col1 col2 col3
1 23 34
2 45 56
3 23 56
4 34 68

For each row I would like to calculate the means of the numbers stored in
col2 and col3.
How can this be done in R?
TIA,
Anjan
