Thanks for replying. Apologies for not putting the code, I have not deviated from that used on the website I linked to.
>Can you show the exact code you used please? I am using: #below is Species_1 etc org <- read.table ("Organisms.S", header=TRUE, row.names=1) #below is environmental variables env<-read.table ("Environment.S, header=TRUE) attach(env) library(vegan) cca.1<-(org~Temp+Water+etc) cca.1 At this point I have noticed (this morning) that I should be getting the CCA come up here, and this is working with test data but not my actual data which is formatted in exactly the same way. If I type: cca(formula = org ~ Temp + Water+etc, data = org) at this point, I get what looks like but (you're right) might not be an output. For the graph I was then trying to use: cca1.plot <- plot(cca.1,choices=c(1,2)) at which point I get error messages. >Also, not sure why you are attaching anything As I said, I'm quite new to R. It does so on the tutorial linked so had assumed it was to do with being able to access the parameters Temp etc. H -- View this message in context: http://r.789695.n4.nabble.com/CCA-with-Vegan-Plot-problem-tp4649012p4649045.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
