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

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

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

Hi All, Does anybody know of any existing functions that will calculate distance inland from a coastline? It's possible to test if a lon,lat location is land or sea using map.where(), but I need to add a buffer to this of say 2km, to allow for points that are just on the coast, and below the resolution of the worldHires database. I'm working with a marine mammal satellite telemetry

Dear all, As a newbie in R I would like to do the following (simple?) thing: to plot a filled.contour plot over a map showing country boundaries (e.g. for Europe) What i do is: map('worldHires',xlim=c(-10,40),ylim=c(35,70),boundary = TRUE,border=0.1) map.axes() filled.contour(mslp, zlim=c(1000,1020),color.palette = colorRampPalette(c("blue", "white",

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()

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

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

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. library(maps) library(mapdata)

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

Dear R colleagues, I am trying to plot some geophysical data as a filled contour on a continent map and so far the guidance from the R-help archives has been invaluable. The only bit that still eludes me is the colour key (legend) coming with filled.contour: I prefer to generate my own colour palette, mainly based on the quantiles of tenths of the data in order to capture the whole range (of

I have obtained shapefiles for Indian states from here: http://www.maptell.com/index.php?option=com_remository&Itemid=159&func=fileinfo&filecatid=115&parent=category Problem: I want to extract centroid coordinates for each State, but there is some coding problem with the shapefiles that prevents this. #Code: #After extracting the shapefiles from the india_state.zip file, then:

Hello, I am trying to draw geographical maps with the maps package. However if I try to access the data following error occurs: > require(maps) > map() Fehler in zip.file.extract(file, "Rdata.zip") : 'destination' existiert nicht # Error in zip.file.extract(file, "Rdata.zip") : 'destination' does not exist > traceback() 4: zip.file.extract(file,

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

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

I've generated a levelplot showing the density distribution of a species derived from survey transects, with lon, lat co-ordinates. I'd like to overlay this on a map of the study region specified by: map('worldHires', xlim = range(mlon), ylim = range(mlat)), where mlon, mlat specifies the study region. I've tried plotting the map first, then using the options: 'add=TRUE,

Hi List, I would appreciate any suggestion on how can I make a text I’ve inserted in a plot show some contrast? With this I mean that I have a white text on a plot and I would like to make a tiny border around it in black, so even being small sized and the entire graphic being small in the text page I’ll insert it. It will be visible. Well I tried inserting a box() function inside the text()

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

Hello all, I worked fairly enough with PHP and MySQL, but am very new to Ruby. I have Windows machine with Apache and MySQL installed previously. Both Apache and MySql were stopped while installing Ruby. I tried several ways to install Ruby 1.8.7 and one-step installer. I can use Ruby with netbeans 6.0.1 with its own Ruby or with the one I installed now. The problem starts when I try to create
