Subject: [R] Descriptive statistics for tables
I have a lot (more than one hundred) of files with tables of
the same kind (quadratic, same size) and I want to obtain
some statistics for every position on them. Therefore, as a
result I want another table. I import every table, and create
an object read.table for it, then I have try to create a
list or a data frame and directly utilize some functions
like sd( ) without success, because it calculate sd for the
columns . Which kind of object should I create in order to
utilize directly this kind of functions? Should I program it
throw for loops?
