[R] Problems when plotting (related to RArcInfo)

[Virgilio Gómez Rubio]

Hello,

I am using RArcInfo to create some maps but, once I have plotted the map
(using plotarc), I try to add new lines, but the fact is that they are
not plotted.

I have reviewing the code, and if I remove a line, everything works
fine, but I am not sure whether I should do that, because that line
restores the previous 'par' profile.

Here is a portion of the code (from plotarc.R):


                par.in <- par(no.readonly = TRUE)
#               on.exit(par(par.in))  <--- THIS IS THE LINE I MENTIONED

                plot.dim<-c(ymin-xmin, ymax-xmax)
                par(pin = min(par.in$pin)
                * par.in$fin / max(par.in$fin)
                * (plot.dim) / max(plot.dim))


I am not sure whether some 'read only' flag is set with that command.
can anyone help.


Thanks and best wishes,
