Hello, for my project I wanted to create a side-by-side barplot. For each of 143 treatments there are always two measurement. This two measurements (a pair) are represented by a red resp. a yellow bar. I was able to write the code for the side-by-side barplot. Unfortunately however I am not able to vary the distance between the measurement pairs ( the distance from one red-yellow bar pair to the next). How can I do this in the case of a side-by-side barplot? In a normal barplot this can be done by using the command: "space()" but in the case of a side-by-side barplot it is not working( in fact if I work with the "space" command R is changing somehow the coloration of my bars). I would be very grateful if anyone could help me with my problem. Thank you very much
My R code: barplot(t(data), beside = TRUE,ylim=c(0,200),col=c("red","yellow"),main="Species rank curve",ylab="Number of individuals") Yours sincerely M.Eisenring PS: This is the first time I am using the R mailing list.
