non-finite location and/or size for viewport (Gviz error)

Question

[nasim.zeeshan25]

Hi,

I am unable to use the Gviz genetrack. When I try, it gives me the error

Error in grid.Call.graphics(L_setviewport, vp, TRUE) :
non-finite location and/or size for viewport

Details are here:

Has any one faced the same problem?

Thanks
