Bug (?) when getting google maps that are not square

[jonnybaik]

It seems that the function get_googlemap does not like it when I request a rectangular map size.

I have R 3.0.0 running on Ubuntu 12.04 and ggmap version 2.3. When I run the following code, the map is not what I expect.

map_center <- c(lon=-123.1119, lat=49.2505)
test <- get_googlemap(center=map_center, zoom=3, maptype="satellite", size=c(640,320))
ggmap(test)

When I change the size parameter to any square dimensions, I get a nice map

It seems that the temporary file, ggmapTemp.png, is correct, but the plot displayed by ggmap is distorted.

Does this problem still persist?

@krlmlr Yep, I'm still getting this error as of ggmap_2.5.2 and ggplot2_1.0.1

Square

goog_map <- get_googlemap(size = c(200,200), zoom = 6, scale = 2)    
ggmap(goog_map, extent = 'panel')

Resulting URL: http://maps.googleapis.com/maps/api/staticmap?center=29.763284,-95.363271&zoom=6&size=200x200&scale=2&maptype=terrain&sensor=false

200x100

goog_map <- get_googlemap(size = c(200,150), zoom = 6, scale = 2)    
ggmap(goog_map, extent = 'panel')

Got it, thanks for the bump!
