...but also seek the thoughts of the R-help community. I have a set of EventData, which I want to plot as points, and to color the points according to some criterion. It turns out that some of my points fall outside my desired plotting region. It looks like this causes the PBSmapping functions plotPoints and addPoints to incorrectly deal with the color assignments. Consider the following toy example: ### Begin Example ### library( PBSmapping ) # Define some EventData events <- as.EventData( read.table( textConnection( 'EID X Y Color 1 494 1494 red 2 497 1497 blue 3 500 1500 green 4...

...ecided to take some bitmapped format when passing 5.000 datapoints, because most of them are in one cloud. As a result, the png is nice and fast to handle and in Linux it is very easy to convert it to pdf with imagemagick. So far so good. The problem is, that the font size and the point-size of the plotpoints and the all of the plot is getting much smaller when using png-format. Why is this and how can I circumvent this issue? These are the two devices, I am opening for the two reasons: 1) pdf("name_out.pdf",11,3.5) 2) bitmap("name_out.png",height=3.5,width=11) all should be the s...
