Dear All,
I'm new with mapping and using shapefiles in R.
I use the version: R 3.2.1 GUI 1.66 with Snow Leopard Mac OS (6956)
I want to build a map of the countries of Africa, in order to add points of collecting species of beetles, for later publishing.

When I put the extreme coordinates of Africa, the map began only at longitude 0? and thus lacks the

I've installed the Becker and Wilks maps, mapdata, and mapproj packages
so I can begin to try these out for some work I need to do on a map of
Alaska but I don't know where to find a map of Alaska. Has anyone solved
this already and could help?
Thanks very much in advance,

thematic map of USA
My goal is to prepare a thematic map of the US, with states shaded
according to their values for a variable of interest. I would like to
include an inset for Alaska in the upper left and an inset for Hawaii in
the lower left. If possible, I'd like to use Albers conic projection, or
something similar. Thus far I have tried using the maps package with
its state database (which omits

separate maps in one figure
My aim is to create a figure consisting of three maps: Alaska in the
upper left corner, the 48 contiguous US states in the center right, and
Hawaii in the lower left corner. In some ways the figure I'm trying to
create is analogous to figure 1.5 in Paul Murrell's excellent "R
Graphics", which combines a map of New Zealand with a map of the world.

Drawing maps in R?
What tools and documentation exist for producing maps and working
with polygon and polylist objects in R beyond the following:
* Packages maps, mapproj, maptools, and mapdata.
* Becker and Wilks (1993, 1995), listed as references in the
documentation on the "map" function.
Thanks,

R maps now for Windows
The original S maps package, previously only available in R on Unix
systems is now available in R for Windows.
maps_2.0-2 and mapdata_2.0-2 (see below) in both source and Windows
binary form (for rw1071) have been uploaded to CRAN, hopefully soon to
appear.
The key aspect of this package which differentiates it from other

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,

problem with "which"
Hi,
I'm having trouble with the "which" or the "seq" function, I'm not sure.
Here's an example :

> lat
[1] 1.0 1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 2.0
> which(lat==1)
[1] 1
> which(lat==1.1)
[1] 2
> which(lat==1.2)
[1] 3
> which(lat==1.3)
[1] 4

add city and point in the map
Dear Helpers:
I'm trying to use packages "maps" and "mapdata" (see blow) to display the research resutls on map (Mid-Atlantic region).

Also, I need to mark several cities that I

maps library for R?
Hi there,
Does it already exist a library in R to draw maps (something like a Generic
Mapping Toolbox, http://gmt.soest.hawaii.edu/ port).
I've seen in an old R-help that Ross Ihaka once tried to port the S-plus map
library (http://maths.newcastle.edu.au/~rking/R/help/99b/0832.html ).
Anybody know if this package is available somewhere or if there is somebody

is there a package in R that would allow map drawing:
coastlines, country/state boundaries, maybe
topography,
rivers etc?
Thanks for any guidance,
