Hi everyone, Have sample of items for each one, a set of 20 dichotomous (absent-present) variables are expressed. I'm trying to understand how to explore the co-occurence of each variable. Read some papers concerning smallest space analysis, but it does not seems implemented in any R package (and my protamming skills are =0). Non metric MDS gives error messages, probably because of the dichotomous character of my variables. My aim is basically to obtain a 2D plot with cooccurence expressed as distance between plots (variables). Any advice to such issue?
Thanks in advance and sorry for this long post marco -- View this message in context: http://r.789695.n4.nabble.com/Dichotomous-variables-tp3721550p3721550.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.
