(1) selection of parameter site and part: ok (2) read txt file as list: problem with (1) as there are NA's (the lines not selected) (3) barplot: 5 different groups of bars (the selected columns H5,H8, S5,S8, C8). In each group 4 different bars (parameter diversity) --> error in -0.01*height: non-numeric argument to binary operator PROBLEM As (2) gives NULL, I think that there is a mistake in my r-script with the vector/list function. Thanks Sibylle R-Code PA<-read.table("Biotree_partitioning.txt", header=TRUE) KANE<-which((PA$site=="KA")&(PA$part=="NE")) KANE.LIST<-vector("list", dim(PA[KANE,])[2]-4) KANE.LIST barplot(KANE.LIST, col=as.numeric(PA$diveristy)) -- -- GMX DSL Doppel-Flat ab 19,99 €/mtl.!
