[R] glm pairwise interaction coefficients

I am trying to recreate the analysis of the recent Kirwan et al paper in Ecology [9(80), 2032-2032]. The SAS code is available but am having troubles getting the R equivalents. The SAS code is: *Model 5 - Species-specific interaction coefficients; PROC GLM; where N=150; MODEL YIELD=G1 G2

[R] Combine colors and shading lines

Hi, basically I am trying to create a grouped bar graph with each group a different color and a bar in each group to have shading lines. Basically combine the 2 graphs created below. Thanks, Josh data(HairEyeColor) a <- as.table( apply(HairEyeColor, c(1,2), sum) ) a1<-a[1:2,] par(mfcol=c(1,2),

[R] Re move a number from a vector

This should be an easy one, but I haven't been able to figure it out, x<-c(2, 4, 6, 9, 10) #how do I remove a single value x<-x[-2] # will remove the second element of the vector not the number 2 This is part of a loop that looks a little like this... x<-c(2, 4, 6, 9, 10) remove.value<-4 #the
