Re: [R] Problems with labeling a set X axis in chron plots
HI,
I couldn't get your problem exactly, but if you are looking for dates on
x-axis, then try using
axis.Date() option.
you can give the weekly, daily sequence if you like.( I am trying for a
6-hour sequence, but hasn't got it yet).

Re: [R] PDF append help
Hi,
I need to append my multiple plots in pdf files.
my problem is that I would want to run the R script a number times(closing
and opening) and still want to append. If i keep the dev.off() it wouldnt
let me see my plots while R is open.
any idea!!
