Hi there,
This will be a pretty easy question to answer, but since I am still
getting my feet wet with R, any help will be very much appreciated.
I am trying to use the npmc (non-parametric multiple comparisons)
package on my data set. Because there are 12 treatments, there are 66
post hoc comparisons. The package returns a very nice table, but I am
having trouble interpreting it, because the comparisons are relabeled
with numbers (1-2, 1-3, 1-4, etc...) instead of the labels that I've
given each treatment in the vector "class"
It seems as though setting the argument "info" should be able to return
information like the names of the compared groups, but when I try to
use "group.index" or when I try to set info=TRUE, I get these errors,
> npmc(data,info=group.index)
Error in npmc(data, info = group.index) : object "group.index" not found
> npmc(data,info=T)
Error in npmc(data, info = T) : unused argument(s) (info = TRUE)
Has anyone used this package and have any idea how to decipher what
numbers correspond to what comparisons?
Thank you, in advance! Cris
