descriptive statistics
Hi. In a data set I have a variable that takes values from 1 to 14. For each
subgroup of values of this variable, I would like to obtain some descriptive
statistics of other variables present in the data set. I've been trying with
a "for" loop but I couldn't get nothing. Could you please suggest me some
lines?

number of items to replace is not a multiple of replacement length
Hey all,
I am writing a function in which I will have a matrix of 4 columns and a
variable amount of rows.
The first to columns will always contain be of the Character type, the third
and fourth columns
can be a variation of data types, usually characters and integers, but
sometimes lists or matrices.
At one point the code makes, for each row, a copy of that row, then it makes
some adjustments

#c contains c parameters
#b contains b parameters
#xi is a one column vector containing quadrature points for xi(=theta-gamma)for one item
tmp <- a*(xi-b)
