R help - Mar 2012 - Error in par(pin = p) : invalid value

Dear list,

I am getting an error message with "pin" and I am not quiet sure how
to fix it.

library(maps)
op<-par(mar=c(1,1,1,1))
map(xlim=c(-40,-45),ylim=c(60,65), boundary=T, fill=T, col='gray95')
>Error in par(pin = p) : 
  invalid value specified for graphical parameter "pin"

par("pin")
> par("pin")
[1] 8.188889 8.188889

I saved an earlier map in ggplot2 and changed the width & height of my plot
window. Is this now affecting my par("pin") values....?
ggsave(file="newmap.pdf",width=16,height=9)

Thank you,
Aurelie

The problem is your setting for xlim:  map() wants xlim[1] < xlim[2]. 
Perhaps it could give a more informative error message...
