labels on map
dear all:
Im trying to obtain maps on R, under mapdata library, but I cannot define the labels.
Here is an example:
library(mapdata)
map("worldHires", c("portugal","spain"),ylim=c(34,46),xlim=c(-14,3.5))
axis(1,at=seq(-12,3,3))
axis(2)
when I try the parameter xlab or ylab in axis, i get:
parameter "ylab" couldn't be set in high-level plot()

Maps, Eastern Europe
Dear all,
I would like to employ a European map in a presentation. My idea was to
use:
library(mapdata)
map("worldHires", c("Austria", "Switzerland", "Germany"))
where I include all countries from my analysis as a vector of character
strings like in the example above. Unfortunately, I was unable to
specify the Baltic States (Latvia, Lithuania, Estonia) or

polygons on scatterplot3d
Does anyone have any experience plotting complex polygons on a
scatterplot3d display? I would like to present some spatially binned
data in a 3-d type plot with background polygons (i.e.. a filled
coastline map). I can get the coastline onto the plot window as a
line type but cannot figure out how to fill the shape. I'm certain it
may be possible but might require a bit of digging

diffusing GIS data in maps
Hi-
I am trying to find a way to diffuse GIS data on a European map. I have a
dataset consisting of particular locations scattered across Europe,
along with magnitude and value information. I can plot these as discrete
points with something like the following:
"geocode" is a dataframe with four columns: LAT; LONG; MAGNITUDE;VALUE.

Help with map
I have just learned how to play with map, but something weird
(or not) is happening.
Suppose I want to draw a map of two countries (that have disconnected
components), like Argentina and Brazil.
If I command:
library(maps)
library(mapdata)
map("worldHires", c("Argentina", "Brazil"))
It works fine. However, if I want to _colour_ the interior:

Masking oceans using polypath
Hi R-help
I am trying to mask the ocean from an image plot I have made.
Here is some example code:
library(mapdata)
image(x=110:155, y =-40:-10, z = outer(1:45, 1:30, "+"),
xlab = "lon", ylab = "lat")
outline <- map("worldHires", plot=FALSE) # returns a list of x/y coords
xrange <- range(outline$x, na.rm=TRUE) # get bounding box

read the middle of a file
Hello,
The other day Justin Peter presented a mini program to plot a topographic map with an overlay of the worldHires. I seemed interesting so I checked the ETOPO5 site and find that there is a new file ETOPO1 with a 1 minute grid. I downloaded it and tried a similar procedure. Now the ETOPO1.gz is 1 Gb and the uncompressed file is 5 Gb. They do not fit into my laptop. I tried the following

filled maps
Hi R-Help,
I would like to make filled contour maps of ocean data overlaid by
costlines from the map package.
I can draw the filled contours and the coastlines om the same plot, but
the filled contour also covers part of the land. To get rid of that I
tried to draw a filled coastline map on top of the filled contour, but
the filled map only draws the closed contours - so most of the land is

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,

Plotting a kriging on a map
Hi list,
Well, this time I’ve a doubt with mapping generation.
I was already able to read and plot shapefiles, plot point on this map. All
this without any problems, but now I want to do something that I think, only
Golden Software Surfer is capable of.
I would like to plot a kriging result on the existing map (map script
below). Well I looked for on the net, but I was not able to be sure of

Do you know if you can map a large minimum spanning tree in R?
Thanks Mike.
My data has longitude and latitude coords and I used distAB {clim.pact}
then mst {ape} to calculate my minimum spanning tree. The nodes are
telecoms sites from all over Australia. My goal is to determine the
minimum cost of linking them via cabling, and I'm starting by
calculating the distance "as the crow flies", but will probably
eventually need to calculate the

North Arrow (.png file) on a Map
Hi list.
I would like to know how do I insert a North arrow, stored as a png file in
my computer, in a map? I found lots of post asking similar things, one of
them mentioned the pixmap package. The map was done using map() and
shapefiles (the code is below). I’m using the pixmap () and addlogo()
functions. Well I can import the png with pixmap() function (I guess, once
there’s no error message),

[newbie] how to find and combine geographic maps with particular features?
SUMMARY:
Specific problem: I'm regridding biomass-burning emissions from a
global/unprojected inventory to a regional projection (LCC over North
America). I need to have boundaries for Canada, Mexico, and US
(including US states), but also Caribbean and Atlantic nations
(notably the Bahamas). I would also like to add Canadian provinces and
Mexican states. How to put these together?

plotting points on a map, assigning vectors to values from dataset
Dear everyone, as a newbie I fear I have made an easy mistake and am just too
blind to see it. Can anyone help me seeing the (possibly) obvious?
I have a command that creates a map of South America. In a separate
txt-file I stored data about latitude and longitude of languages, and in a
third column values that differ from language to language. The command
should read that file and assign the

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,

German Map in package maps
Hello everybody,
I'm an absolute newbe in R, so please be gentle to me.
I am looking for a german map in the package maps by Becker and Wilks.
After that I want to draw the German cities from world.cities of this package in the map and want to draw further a line from Berlin to Munich.
Has anybody an idea?
Thank you so much and sorry for the question!
Best regards from Berlin,

3d topographic map [SEC=UNCLASSIFIED]
Hi Sherri,
There are examples of topographic maps which you have been pointed to, however, I suspect that you want to know where you can obtain topographic data from rather than a canned example.
There are quite a few intricacies to the process so I will go through them for you.

Topography files can be found in the geomapdata library. You will probably want to use the maps package too (if

Map of British Colonial America 1775
Does anyone have suggestions about how to produce a map of British
Colonial America 1775? At that time, Great Britain had 26 colonies in
the Americas, including Bermuda, several Caribbean islands, "Quebec"
(extending then almost to New Orleans), Nova Scotia, Newfoundland,
Belize, and the 13 that declared independence in 1776.
