[R] ggmap warning

[Chichi Shu]

Hi, 

I limit my data to just two fields. Longitude and latitude. I first used is.finite to check each of the long and lat values to make sure they are finite values.

Then when I use ggmap again, it still tells me that it removed the majority of the records bec of non-finite values.

Any other suggestions?

Thanks!

Your data contains 4945 rows with missing or infinite values. These cannot be handled by stat_density2d and are dropped for that reason.

Best regards,

Thierry

  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!
