Here is how I found how to do it

test=read.table("clipboard")
test
    V1   V2   V3   V4   V5   V6   V7    V8   V9
1 9.56 8.67 9.28 8.81 7.93 9.85 8.92 10.19 8.63
2 6.36 7.29 6.68 7.11 8.04 6.05 7.04  5.80 7.34
3 3.22 3.22 3.28 4.37 5.21 3.10 3.37  2.56 5.43

test1<-t(test)
??error
library(Hmisc)
?errbar
starting httpd help server ... done
test.m<-colMeans(test1)
test.sd<-apply(test1, 2, sd)
errbar(1:3, test.m, test.m+test.sd, test.m-test.sd)

Is it OK?

Regards
Petr
