How to perform a calculation in each element of my list?
Hi R-helpers,
I have a list containing 10 elements, each of which is a dataframe. I wish
to add a new column to each list element (dataframe) containing the product
of the last two columns of each dataframe.
I'd appreciate any pointers, thanks!

R: mean from list
great!! thanks very much, mean(unlist(lapply(listdata, function(z) z$c)))
works well.
and what about getting the average table $a (displaying the average elements
across all 1000 matrix)? could you please help me? I am struggling with
this...
thanks in advance
Roberto
mean(unlist(lapply(x, function(z) z$d))) should do the trick
