Indicator Species analysis; trouble with multipatt
Hi Ansley, Without your data file (or a meaningful subset) we can only guess, but you may be trying to define groups on the columns rather than the rows of the data set. Usually rows represent cases and each case must have a value for the grouping variable. Jim

Hello, *Error in tx %*% comb : non-conformable arguments* Suggestions greatly appreciated. I am a beginner and this is my first time posting. I would like to get the summary for indicator species analysis, using package indicspecies with multipatt. I am getting errors, I believe, do to my data organization. After reorganizing and reorganizing, nothing has helped.
data<- read.csv(file="Data1.csv", header=TRUE, row.names=1, sep=",") ap<-data[c(1:24, 1:81)] groups<-c(rep(1:4,6)) indval<- multipatt(ap, groups, control = how(nperm=999))
