How to get a map in the range of latitude and longitude?

Question

How to get a map with certain minimum and maximum limits of latitude and longitude using ggmap in R?

I am new to using ggmap and now I was able to implement this:

center <- c(mean(src$longitude),mean(src$latitude)) zoom <- min(MaxZoom(range(src$latitude),range(src$longitude))) hdf <- get_map(location=center,zoom=zoom) 

The help file says that the location can be referred to as an address, a longitude / latitude pair (in that order), or a left / lower / right / top bounding box. I could not find useful material on implementing the restrictive framework for ggmap online.

I'm not sure if you can do this at the boot stage, but what about at the build stage:

 map <- get_map() p1 <- ggmap( map ) p2 <- ggmap( map )+ scale_x_continuous( limits = c( -95.5 , -95.3 ) , expand = c( 0 , 0 ) )+ scale_y_continuous( limits = c( 29.6 , 29.8 ) , expand = c( 0 , 0 ) ) require( gridExtra ) grid.arrange( p1 , p2 , nrow = 1 )
