Hi, there,
I am using "lda" function in MASS with R. I have several datasets, some are
small and some big (say, 40 by 6800). I ran the following command on small
datasets smoothly
z<-lda(dat,g,CV=T) # dat is my dataset, g is the group labels
but for big datasets I got error message like,
Error in x - matrix(dm[i, ], n, p, byrow = TRUE) :
non-conformable arrays
In addition: Warning messages:
1: variables are collinear in: lda.default(dat, g, CV = T)
2: Replacement length not a multiple of the elements to replace in matrix(...)
I double checked the dim of dat (40 by 6800) and g (length=40) and didn't have
idea what's wrong. Could anyone give me some clue about this? Any info will be
highly appreciated.
thanks,
Sophie
