[R] Problems with plot maps

[Pascal Oettli]

Hello,

I cannot reproduce the error:

 > library(ggplot2)

Attaching package: 'ggplot2'

The following object(s) are masked from 'package:latticeExtra':

     layer

 > library(cshapes)
Loading required package: maptools
Loading required package: foreign
Checking rgeos availability: TRUE
Loading required package: rJava
Warning: replacing previous import 'show' when loading 'rJava'

 > cshp.data <- cshp()
 > map <- cshp.data[cshp.data$COWCODE==369,]
 > map_mp<- list(
+     geom_polygon(aes(long, lat, group = group), data = map, fill = 
"grey70",
+                  colour = "grey60", inherit.aes = FALSE, show_guide = 
FALSE),
+     scale_x_continuous("", breaks = NULL, expand = c(0.02, 0)),
+     scale_y_continuous("", breaks = NULL, expand = c(0.02, 0)))
Regions defined for each Polygons
 > ggplot()+map_mp


Here are the some details of my configuration:

R version 2.15.2 (2012-10-26)
   |- ggplot2_0.9.3
   \- cshapes_0.3-2
        |- maptools_0.8-20
        |- foreign_0.8-51
        \- rJava_0.9-3
