ggmap Map Designs

[Scott McCain]

Hello!

I'm trying to plot points (with lat/long values) on a map using ggmap.

When reading the "ggmap: Spatial Visualization with ggplot2" (Kahle and Wickham), they talk about using CloudMade maps for flexibility. However Cloud Made is no longer giving out APIs I believe (see their email response below).

I'm simply looking for a map which is white for water and grey for land, with a black outline of land masses. Can anybody suggest a repository for map designs or a place I could make this myself?

Any help is greatly appreciated,

Cheers
