I'd like to perform some calculations across a series of columns. Is there an easy way to do so? For example, I'd like to calculate the maximum value from columns 6-42. Although I can use, say:
pmax(data[,6],data[,7],data[,8], etc.), I'd prefer to be able to do something like pmax(data[,6:42]). Unfortunately, doing so returns 36 columns.
