Hi, I need to determinate HSD value from a matrix like that Thesis Days A1 Cx 0 66.07 Cx 0 60.24 Cx 0 42.86 Tw 0 66.07 Tw 0 60.24 Tw 0 42.86 Aa 0 66.07 Aa 0 60.24 Aa 0 42.86 Qe 0 66.07 Qe 0 60.24 Qe 0 42.86 Cx 56 310.86 Cx 56 223.17 Cx 56 186.77 Tw 56 149.42 Tw 56 127.75 Tw 56 138.59 Aa 56 130.24 Aa 56 214.83 Aa 56 137.95 Qe 56 186.64 Qe 56 189.09 Qe 56 187.87
this is my script require(agricolae) file <- "A1.txt" data_table <- read.table(file, header=T, row.names=NULL) attach(data_table) anova <- aov(A1 ~ factor(Thesis)*factor(Days)) detach(data_table) first of all, I need to know if my script has conceptual errors secondly, I need to calculate HSD between Thesis:Days means I try with Tukey.test command from agricolae package, but it do not work I can use only these commands Tukey.test(anova, "Thesis") Tukey.test(anova, "Days") but not Tukey.test(anova, "Thesis*Days") how can I do? my apologies for the banal questions, but I'm taking the first steps in statistical computing Thanks, Roberto -- View this message in context: http://r.789695.n4.nabble.com/Tukey-HSD-with-repeated-measure-ANOVA-tp3665872p3665872.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.
