[R] USA map

R users,

In S, there was a function called usa() that
would draw the map of the United States, plus
it had other options for graphics.  I have looked
but I can't find the equivalent in R.  Is there one?

Thanks,

Jason

I don't know the usa() function in S but usa() in R gives a map of the US

that's the output of a "usa " search, perhaps that is what you are
looking

P.S.: www.freegis.org -> GeoData is worth a look for more maps

usa() {map}

 This database produces a map of the United States mainland generated from US 
Department of the Census data (see the reference). 

Usage

data(usaMapEnv)

Format

 The data file is merely an assignment to a character string which specifies 
the name of an environment variable which contains the base location of the 
binary files used by the map drawing functions. This environment variable 
(R_MAP_DATA_DIR for the datasets in the maps package) is set at package load 
time if it does not already exist. Hence setting the environment variable 
before loading the package can override the default location of the binary 
datasets.

Where did you find that function? In rw1080 on windows XP I get:

Error: couldn't find function "usa"> 
(and help.search("usa") does'nt give anything usefull)

In the current version, you need to type:
library(maps)
map("usa") 
#or:
map("world2", "USA")

I believe in R you need

library(maps)

before using usa().  Of course, the library has to be installed first.

Sorry, I should have typed

   which indeed shows a correctly-looking map. 

I also tried
> map("worldHires","sweden")
> map("worldHires","denmark")  # which comes out very
small since it                                               # includes the Faroe   
                                               # islands properly far-
                                                # away

                                           # than Andorra

but I cannot find any function to find the avalable region names in
a map database

Try:
library(maps)
data(worldMapEnv)
file.show(paste(Sys.getenv(worldMapEnv), "world.N",
sep="/"))

These ASCII files are in the form:
region[:subregion] polygonNumber
