Hello,

I have written a small script to read a dataset, compute some basic
descriptives and write them to a file (see below). The variable

"maizeseedcash" of which the statistics are calculated is contained in

the data frame agr_inputs. My question is whether there is a way to make
R compute the statistics not only for maizeseedcash but also for other
variables in the dataset. I thought about a thing like a loop which
repeats the computations according to a set of variables which I would
like to be able to specify before. Is something like that possible and
if so, how would it look like?

Best regards,

Uli

solution<-data.frame(Measure, maizeseedcas)

print (solution)
