?plot  # ylim

and you need to have the data in a form (before plotting) where you can determine the shared max and min for the y limits

Hi All,

Can anyone please help me with getting a single x and y-axis label while
plotting muliple plots.

I'm still not sure what a single x-label might mean for such disparate series.

Here is the code:

par(mfcol=c(2,2))
plot(x <- sort(rnorm(7)), type = "s", main = "", ylab="", xlab="")
plot(x <- sort(rnorm(27)), type = "s", main = "", ylab="", xlab="")
plot(x <- sort(rnorm(47)), type = "s", main = "", ylab="", xlab="")
plot(x <- sort(rnorm(67)), type = "s", main = "", ylab="", xlab="")


randlist <- list(); randlist[[1]] <- sort(rnorm(7))
randlist[[2]] <- sort(rnorm(27))
randlist[[3]] <- sort(rnorm(47))
randlist[[4]] <- sort(rnorm(67))
lapply(randlist, plot, ylim=c(min(rapply(randlist, min)), max(rapply(randlist,max))), type = "s", xaxt="n", main = "", ylab="", xlab=""); par(opar)

A minor refinement:

opar <- par(mfcol=c(2,2))
lapply(randlist, plot, ylim=c(Reduce("min", randlist), Reduce("max", randlist)), type = "s", xaxt="n", main = "", ylab="", xlab="")
par(opar)


also, how can remove x-tick lables using plot()?

?par  # xaxt="n"


Thanks,
Xin
