Unexpected behavior in PBSmapping package
...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 5...

png and pdf : point size, font size, etc.
...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 sa...
