Take the maximum of every 12 columns
Dear all,
I have monthly data in wide format, I am only providing data (at the bottom
of the email) for the first 24 columns but I have 2880 columns in total.
I would like to take max of every 12 columns. I have taken the mean of
every 12 columns with the following code:
byapply <- function(x, by, fun, ...)
{
# Create index list
if (length(by) == 1)
{
nc <- ncol(x)
