Hi,

I have a file named:
test_R.txt
aaa  2
bbb  5
ccc  7
sss  3
xxx  8

I want to have a plot:
test<-read.table("test_R.txt",col.name=c("Name","Score"))
par(mfrow=c(1,2))
barplot(test$Score)
name<-test$Name
axis(1,at=1:length(test$Name),labels=paste(name))

Q1, if you try the script above,you will get 5 bars, the axis only shows
"aaa", "ccc","xxx", but where are "bbb"&"sss"?

Q2, pls have a look this x-axis again, you will find the middle of the bars
are not pointing to the x-axes.

Q3, how can i change the width of the bars? I feel they are too "fat".

Thanks!
Nina
