Dear all,
I'm trying to plot some data over a geographic map.
I'm reading the documentation (?map)... The problem is here:
*map(database = "world", regions = ".", exact = FALSE, boundary = TRUE,*
* interior = TRUE, projection = "", parameters = NULL, orientation = NULL,*
* fill = FALSE, col = 1, plot = TRUE, add = FALSE, namesonly = FALSE,*
* xlim = NULL, ylim = NULL, wrap = FALSE, resolution = if(plot) 1 else 0,*
* type = "l", bg = par("bg"), mar = c(4.1, 4.1, par("mar")[3], 0.1),*
* border = 0.01, ...)*
*
*
*Arguments*
*
*
*database*
* ** character string naming a geographical database, or a list of x, y, and
names obtained from a previous call to map. The string choices include a
world map, three USA databases (usa, state, county), **and more (see the
package index).** The location of the map databases may be overridden by
setting the R_MAP_DATA_DIR environment variable. See world for further
details.*
According to the help, the package comes with a world map, with three usa
databases *and more (see the package index).*
*
*
*My doubt is: what it means with see the package index? Should I find a
Brazilian map on the index?*
*
*
*If not, can someone help me to find some brazilian map (with states)?*
*
*
*I'm trying to plot something similar to it:

*
*
*Also, can someone suggest me some good site with documentation about
plotting graphics in R? I'd like to read more about this amazing tool.*
*
*
*Thanks in advanced, again,*
*
*
*best regards*
