editor: not possible to change the variable name
Hi again everybody
I have I new problem concerning the editor of R. It is possible to add a
new variable column, but they all have the name "var1".I read somewhere that
it should be possible to change the variable name by clicking on it, but
that doesn't work. Is that a bug or how is it possible to change the
variable header?
Many thanks
Matthias

how to calculate the mean of a group in a table
Hi its me again
I don't mean to get on your nerves, but the use of R proofs to be a bit more
complicated than envisaged.
I would like to calculate the mean of a group of values, here
"wage_accepted". The group is determined by the stage and period, so in the
end there should be a column with the values of the wages in period 1
stage1, period 1 stage 2, period 2 stage1...
