R help - Jan 2010 - How to control number of significant digits (figures) in y-axis?

Dear R users,
I encounter a problem regarding number of significant digits on y-axis.
Below is my basic code:
myplotkid<-xyplot(expected_offspringnumber~afr|decade,groups=SES,data1,
auto.key=list(space="right"),layout=c(9,1),xlab="",ylab="Offspring
number",
aspect="fill",scales=list(x=list(draw=F)),strip=T)
>From this code, you can see there are 9 small panels in a single row. Thus,
there is only one y-axis in the left. However, number of offspring displayed
is in integer. How to display such numbers in decimal numbers, e.g. decimal
number with one digit after decimal point? Does someone have any idea to
fulfil this aim?
Thank you very much for kind help!
Best regards,
Jianghua

Use the 'scales=' argument together with formatC:

x <- 1:10
y <- sample(10)
xyplot(y ~ x,
   scales = list(
              y = list(
                at = 1:10,
                lab = formatC(1:10,
                  format = "f", digits = 1))))

?formatC
?xyplot
