[R] Multiple Range Means Test

, trt, DFerror, MSerror, alpha = 0.05, group=TRUE, main = NULL) When I try to run it as duncan.test(aov, dat, 6, .297, alpha=.05, group=TRUE, main=NULL) it gives me an error message that I have differing rows, 0 and 163. 163 is the correct number, where is it getting the 0 from? Thank you, Amanda

[R] Coefficient of Variation, NA, Aggregate

unction to work? SECONDLY, how can I then get that function to work within an aggragate? Do I still use >aggregate(. ~ subspecies, data = rowleyi, CV, na.rm=TRUE) #where subspecies is >the header for rows? This has worked for mean, std.error, sd, etc. Th
