Sure I did, but once data is in R in a proper format, you can create rows
with R tools quite easily. Though, getting first step done, is not always
obvious to me.
Maybe this is a extrem case, but the files I get hardly ever work with
read.table and it is done. People outside of R do not prepare it well
enough...

No doubt that I believe you on this matter! I did not want to complain in
general, but R could make it easier for newbies. R does great analysis but
preparing the data has to occur for good parts by hand. On this matter other
programs do a slightly better job.
I am only saying that a wide tutorial on preparing and filtering data would
be helpful.
My critique sounded a bit harsh, I apologize for that, but please see that
for newcomers with little programming experience the point of frustration is
getting the stuff into R and the help function is not a great help for that.
My colleques and I in our class on introduction in R, usually do not fail
using the stuff we learned but in preparing the data for the use of the
function.
It is like a magic barriere R keeps or wants to keep alive. These are just
my two cents.
Anyway, I thank you a lot for your advice and it will be well remembered.
