Hi, I have searched and found a response to a question similar to mine but when I tried the code, R says it's not an actual function so I thought I'd ask here.
http://r.789695.n4.nabble.com/file/n4633035/Cookies.csv Cookies.csv I have attached the data I am using. I am trying to look at two things: how moisture content changes over time, and how it changes along the length of a log (bolt). My data is not normal and doesn't become normal after ArcSin or Log transformations. Because the 'Days' has 4 levels, I performed a Kruskal-Wallis (kruskal.test) and got significant results. Same for comparing 'Cookie'. Neither of these have only 2 levels so significance here doesn't really explain it in depth....but everything I'm finding for post hoc with a KW says Mann Whitney. But when I try this (wilcox.test) in R it doesn't work - bc it should only have 2 levels. Can I simply run a tukeyHSD to see differences between levels? -- View this message in context: http://r.789695.n4.nabble.com/Kruskal-Wallis-Post-hoc-tp4633035.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ [email protected] 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.
