Plot SpatialLinesDataFrame with xlim & ylim
I'm running windows xp, R 2.3.1 with maptools 0.6-6, I guess.
When plotting from a large SpatialLinesDataFrame and using xlim & ylim to reduce the area, the plot axes automatically have the same scale size, even if xlim and ylim ranges differ.
E.g.:
tmp <- readShapeLines(filepath)
plot(tmp,xlim=c(-126,-119),ylim=c(50,51))
The y-axis range is actually 47-54, same range as the x-axis.
