Hello all,
I found a funny problem with y-axis labels when plotting acf(matrix) -
the labels are too close to one of the margins and cut in half.
Here's the problem:

test<-matrix(rnorm(200),ncol=4)
acf(test)

This doesn't fix the problem:
test<-matrix(rnorm(200),ncol=4)
par(mar=c(3,3,2,0.2),oma=c(0,0,0,0))
acf(test)

This does fix the margin. I understand why, but not sure why ONLY this
will work?
test<-matrix(rnorm(200),ncol=4)
acf(test,mar=c(3,3,2,0.2),oma=c(0,0,0,0))
