R help - Dec 2004 - How to change x axes' range

Hi, there:

When plot ann predicted results I need to indicate numbers of inputs for
each column. 

        V1       V2         V3          V4
1  86.2700  49.9380  30.7630  0.1327
2  89.5127  55.9707  33.7683  0.1186
3  91.1833  58.4670  34.5610  0.1134

matplot(t, pch = 1:4, type = "o", col = rainbow(ncol(t)),xlab =
"No. of
inputs ",  ylab = "Mean of 6 Datasets", main =
"xxxxxxxxxxx")

Instead of have typical x axes' range as "1, 2, 3, and 4" for each
column, I
need to indicate "11 Vars, 10 Vars, 6Vars, and 4Vars" or "A, B,
C, and D"

Does anybody know anything about it? I appreciate if you could help me out.

Thank you very much indeed.

Qin

matplot(.., axes=FALSE)

then custozie by yourself ayour axes 

->axis(1,at=1:4,label=c("11 Vars","10
Vars","6Vars","4Vars"))

?axis and see label option for more details

Add xaxt="n" in matplot(), then follow by axis(1, at=1:ncol(t),
labels=c("A", "B", ...)).

Try suppresing the axes with plot(...,xaxt='n')

and adding a custom axis with the command

axis(1,labels=LETTERS[1:5],at=1:5)

see ?axis for more info
