Hello Everyone,
I am having problem in defining specific axis for
plotting a vactor.
vecAVG <- c(0.2, 0.4, 0.6, 0.2, 0.4)
names(vecAVG)<-c("brain","heart","kidney","lung","blood")
par(mar=c(12,4.1,4.1, 2.1))
plot(sort(vecAVG,decreasing=TRUE),type="p",pch=19,col="darkslateblue",axes=FALSE,ann=FALSE)
g_range<-range(vecAVG)
axis(1,at=0:length(vecAVG),lab=names(vecAVG),las=2)
axis(2, las=1, at=0:g_range[2])
After these commands I am getting the graph but it does not have any Y axis.
I know I am making a silly mistake somewhere. Can someone please guide me.

The expression
0:g_range[2]
is not meaningful. The : operator is for integers, while your data is
continuous. Likely, you want something along the lines of
axis(2, las=1, at=pretty(vecAVG))

Can someone please > guide me.I am guessing the you come from a different programming planet where vectors go from 0 upwards. This is the problem: at=0:length(vecAVG) Try: at=1:length(vecAVG) And you should post your error messages with your code. -- David Winsemius, MD Heritage Laboratories West Hartford, CT
