Accurate area map projections
Hi, Could any one point me to the projection, and parameters if necessary, that would show each country/continent with it's area accurately refelcted on the plot? E.g. aitoff vs. albers vs. bonne vs. cylequalearea vs. guyou - they don't all look the same to mee but some of the documentations suggests they are equal area? Of course this isn't my field, so I am largely guessing and am

Map using projection
Hi list, I have a real problem with plotting US state map. When I try to plot the northern state, there will be some blank space in the top of graph (see case 1 example), and when I plot southern states, there will be a blank space in the bottom of plot (see case 2). I spent almost 2 days to figure out a solution, but could not. Would you help me if you know what the problem is? Regards, Alireza

Beginner plot and map questions
Hi, I have not been able to find answers to these questions in the FAQs, manuals, or R-help archives. If answers are available somewhere, please direct me to them. 1.) Is there a way to convert a table (e.g. represented as a data frame) to a function, specifying which columns are input and which column is output? It would seem that this would be useful for plotting experimental results,

[lattice] display a projected map on a layerplot
summary: I can display a lon-lat map on a lattice::layerplot, and I can display a Lambert conformal conic (LCC) map on a spam::image, but I can't display an LCC map on a lattice::layerplot. Example follows. What am I doing wrong? details: I've been using `lattice` (via `rasterVis`) successfully to display global atmospheric data, which works well enough (though I am definitely intrigued

map - mapproj : problem of states localisation

Adding text (coefts) to pairs panels
Hi, First of all, thanks for the efforts of all the developers and contributors - I'm very new to R and at the moment am just using it to create some graphics, but it seems to be quite powerful. I've googled the archives and wasn't able to find anyhting that dealt with this problem, so would appreciate any suggestions/tips. In a pairs plot I'd like to plot a linear regression line

Bubble plot on shapefile - projection issues?
Dear R help list, ? I am working on some data from a study on the habitat use and movement patterns of fish using a marine protected area in Hawaii.? We have a number of acoustic receivers in a MPA, and any time a tagged fish passes within range it records the date and time of detection.? I am trying to make bubble plots?showing the number of detections for each fish at each receiver.? I have been

"Rotated Lat-Lon" projection in mapproj
Hi, I'm trying to plot a field obtained from the atmospheric model WRF-NMM which uses a "Rotated Lat-Lon? map projection. The WRF documentation mentions that: ? Rotates the earth's lat/lon grid such that the intersection of the equator and prime meridian is at the center of the model domain. ? Within the rotated framework the grid spacing is constant, but in an earth-relative

Alternative mail archives?
I have no solution. However I wonder why the mail archives at https://www.stat.math.ethz.ch/pipermail/r-help/ are not searchable by Google. That would perhaps be a solution otherwise, since you can restrict Google to search within just one site. (This applies to some other search engines too.) Since I am also interested in the possibility to search the archive I have just sent a question 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

plotting on map
Hi list, I want to plot state Texas using map function. I wrote the following code to plot the grid boundary for Texas: ################################ library(maps) require("mapproj") longlatLimit<-c(-106.65, -93.53 , 25.93 , 36.49) par(plt=c(0,1,0,1),cex=1,cex.main=1) #Set plotting parameters map(projection="azequalarea",

converting lat-long coordinates to Albers Conical Equal Area coordinates
#################################################################################### We have used maptools to construct state, county, township, census-tract, and zipcode level R maps with an Albers Conical Equal Area projection. We would like to be able to plot the location of weather stations or other point locations on the maps. The data the point locations are in latitude-longitude units

Map projections - converting latitude/longitude to eastings and northings
I am trying to set up a Grass project and need to set up the region so that I can view the map. I can look at a map and find the lat/lon, but the map projection is in UTM NAD38 WGS84 and I need to set the eastings and northings. Is there a package that will help me calculate this in R. thanks -- Stephen Sefick Let's not spend our time and resources thinking about things that are so little

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 GIS related R packages under development is that it is standalone within

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

I have a set of labels that print correctly except it seems the italic text is justr a slanted version of the TeX computer modern normal font... I'm using R v1.8.1 on Windows XP, and I get the same result if I build the pdf using Adobe Acrobat or using MikTeX The labels:
