Having searched and searched I still haven't found what's the problem with my data (I've attached the relevant file). Every time I tried to use the CANCOR-Function I got error messages. So I turned to check my two sets of variables separately by using the "colMeans"-Function. With one set no problem .. but with the other. My input :
struktur <- read.delim("struktur.csv", header=TRUE, sep = ";")
colMeans(struktur)
And the resulting error:
Error in colMeans(x, n, prod(dn), na.rm) :
`x' must be numeric
Check what str(stuktur) gives you... looks like it seeing your numbers as something else.. BTW, I do not to have the attached file, seems to have been dropped before reaching my inbox, so that's all I can suggest. F
