Hi all,
I have a problem with plotting: (R-1.2.2 on
SunOS fluke 5.5.1 Generic_103640-27 sun4u sparc SUNW,Ultra-Enterprise
solaris 2.)
I define a function to switch between plotting on graphics device and
generating a postscript file (which can also be automatically be printed)
plt <- function(view,f,file="") { ## C.Hoffmann, 2001.03.14
if (view>0) f
else {
postscript(file=file,print.it=(view==0))
on.exit(dev.off())
f
}
}
Executing several statements of the type:
plt(1,plot(rnorm(100),rnorm(100),"test")
does not seem to make any trouble.
If I try
plt(0,plot(rnorm(100),rnorm(100),"test")
more than once, I am getting the error
plot.new has not been called yet
and subsequent executions of
plot.new()
are having no positive result. ??????
What am I missing?
How can I open an X "R Graphics Device" if I have unintentionally
closed
it, without q() and restarting of R?
Thanks for help,
-christian
