R package ggmap

[Chichi Shu]

Dear Listers

 

I’ve been using ggmap package to produce crime Heat map. But I’ve noticed the following warning message when executing my code:

 

In loop_apply(n, do.ply) :

  Removed 4945 rows containing non-finite values (stat_density2d).

 

I’ve googled this message but I couldn’t find any good answers.

 

Is this related to ggmap package or one of its depending package?

 

What does it mean?

 

Thanks!

It just means some of the density is cut off from the map, see http://stackoverflow.com/a/28303782

FYI this is an SPSS forum, there are better options for R specific questions, like stackoverflow.
