R help - Jan 2013 - Attempting to confirm a program i wrote in C (normalize 2 datasets, transform into histogram, transform into CDF, perform KS test)

I have written a program in C that two xy datasets, aligns these 2 datasets
based on shared features, transforms them into equal sized histograms,
transforms the histograms into cumulative distribution functions (via GSL)
and finally performs a KS_test.

I am wanting to validate my program's results and figure'd i would use R
but
i am kinda stuck at ithe histograms (I have 2 histogram objects with the
same #bins, weighted by the Y value) right now and not really sure how to
transform these into CDF to perform a KS.test, I looked at the edf function
but got kind of lost.

I realize this is most likely a very basic question but I am just not that
familiar with R :(

Thanks in advanc

It is generally expected that the questioner pose a specific example so the
respondent can have some assurance they are answering the actual question. In
this case please provide a test data set, intermediate results, and final result
generated by your C program. It would also show that you made a reasonable
effort if you showed what steps you tried in R and where you think they went
wrong.
