Question

When I load a map on R’s widget (through ggmap) and run the program directly though R’s console, the map gets properly maximized when I maximize the R’s window.

The same doesn’t happen when I run R through Qt. I am using RInside.
Through Qt when I run R, the widget gets shown indeed (with the map on it), but when I maximize the R window, the map does NOT get maximized. It remains the same sized!

It doesn’t happen in any particular case. It happens all the time I run R though Qt, and never when I run R through R’s console.

What hardware/software information should be presented here?

The simplest R program which causes this:

R.parseEvalQ ("library (ggmap); library (raster);");

qtToR ["currentFileName"] = currentFileName;
R.parseEvalQ ("load (file = currentFileName); print (ggmap (mapImageData));");

Could it be possible that X11 server is not properly installed on my system? Or is this a know problem with print?

Is there any alternative way to get this running properly through ggmap?

Answer 1

A temporary solution to the problem of map not getting maximized is to set the initial dimensions of X11 server.

X11 (width = 11, height = 11);
This shows a nearly maximized window by default, and the map also gets shown maximized.
