I am running R.dll from Dolphin Smalltalk using
    
   Rf_initEmbeddedR(argc, argv);
...
...

when I run the following :
 
a = matrix(c(1,2,3,4),c(2,3,3,3))
heatmap(a)

everything seems to work correctly, but when I resize the window I get a
division by zero error.

Note that if I run :

a=c(1,2,3,4,5)
plot(a)

everything works correctly and the window can be resized without any problem.
