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

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

Plotting shapefiles on existing maps
Dear All, This is probably a very basic question but: I have plotted a map of the Barents Sea and surrounding coastline using: map('worldHires',ylim=c(50,85),xlim=c(5,65),fill=T,resolution=0) map.axes() map.scale(x=30,metric=T) Next, I imported a shapefile with depth contours for the sea: contours<-read.shape("D://My Documents/BarentsSea.shp",dbf.data=T) (This is in

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 yrange

How do we omit the coastline using map?
I've been able to do most things I'd like to using the map package, but I can't figure out how to fill a region without drawing a black outline. I can draw the outline in a specified colour, but as soon as I set fill to TRUE, I get a black outline in addition. My map has a lot of activity on the coastline so I don't want a black line obscuring what I do there. A pale colour to

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

map question
Would anyone with experience with the map functions know how to divide Czechoslovakia into the Czech Republic and Slovakia. They have been two separate countries for some time now. I'm thinking about the worldhires map database in particular. -- Dean Sonneborn, MS Programmer Analyst Department of Public Health Sciences University of California, Davis (530) 754-9516

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:

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

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

Dial pattern sort order
Hi! Is there a simple way for an * newbie to force * to use different sip-trunks for different calls. I have 2 siptrunks, one for inland calls and one for international calls. All in country numbers starts with 0 and all international starts with 00. This I have configured in the outbound routing. But * always use the incountry trunk because the 0. dialpattern is also true for international
