You can put all dataframes into a list L, e.g.

and then do either a for-loop or use lapply. For example
for (ii in 1:length(L)){

One issue you will have is that, if you're using the same cutpoints for
the binning for all three tables, you'll probably get different numbers
of values from each column in each bin, so you won't be able to form a
matrix. Of course, I might be misunderstanding what you mean by
binning :)

i guess you mean columnwise cumsums computed starting from the bottom up?
yes
then this should do (given that your data is in matrix m, and years are
row labels, not data):
rc = nrow(m)
cumsums = apply(m[rc:1,], 2, cumsum)[rc:1,]
ok...work very well..

Hi
I have patched together (from various sources) the following code to get
semi-logarithmic plot. Unfortunately, my labels come out also at
intermediate places between 10^2, 10^3, 10^4 etc. Since I put the code
together from various sources and do not understand fully how the code is

Folks:
Assuming that you want row statistics of each block, it seems to me that
solutions so far proposed are either unnecessarily complex (a matter of
personal taste, I know) or depend unnecessarily on the specific arrangement

I think factor(foo, levels = unique(foo)) works best for my needs.

Some functions behave differently if the factor levels are in
