[rkward-devel] problem with rkward native graphic device

[Kostas Katselidis]

hi,
please find below a detailed report on a problem that I encountered while I
was working with RKWard.
Hopefully, it is not something very serious.

Thanks a lot for the Great Program, keep up the good work

Best wishes,
Kostas A. Katselidis





---Problem description---
Please give a brief summary on the problem:
###
when I try to plot a SpatialPolygonsDataFrame and I am using the 'RKWard
native graphic devise', I got the error message:"
Error in polypath(x = mcrds[, 1], y = mcrds[, 2], border = border, col =
col,  :
  plot.new has not been called yet"

I do not get this error message when I use the 'Platform default device'.

What - in detail - did you do directly before you encountered this problem?
###import with the function readOGR() the shapefile###


When you try to repeat the above, does the problem occur again (no,
sometimes, always)?
###Yes, always###


If applicable: When doing the same thing in an R session outside of RKWard,
do you see the same problem?
###No, the default graphical device does not have this problem###


Do you have any further information that might help us to track this
problem down? In particular, if applicable, can you provide sample data and
sample R code to reproduce this problem?
### R code ###
library(sp)
library(rgdal)
tfurl <- paste("http://biogeo.ucdavis.edu/data/world/countries_shp.zip")
td <- tempdir()                                   # create a temporary
directory
tf <- tempfile(tmpdir=td, fileext=".zip")         # create the placeholder
file
download.file(tfurl, tf)                          # download into the
placeholder file
unzip(tf, files=NULL, exdir=td, overwrite=TRUE)   #extract
countries <- readOGR(td, "countries")             #load shapefile
RK()                                              #load RKWard native
graphical device
plot(countries)                                   #plot
### END of R code ###


RKWard is available in many different packagings, and sometimes problems
are specific to one method of installation. How did you install RKWard
(which file(s) did you download)?
###I am on a Debian system, so simply "apt-get install rkward"###
