similar to: library maps for R

I am using R1.2.0 on Windows NT4.0 and am looking for information on drawing geographical maps. [The things I'd like to do at the moment are rather simple, just like plotting the values of some variable (e.g. a SMR) on a given map.] Searching the r-help mailing list archives, it seems this topic comes up from time to time. For example, in November 1999 Ray Brownrigg writes about an "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 developing a Mapping package

Apologies in advance from an R newbie if this is a dumb question. Is it possible to produce choropleth maps in R? I gather from some nice research papers on the AT&T (sorry, Lucent) S web site that in S (and S Plus) there is a map() function which uses arrays of polylines and regions to draw map borders and then fill them with patterns or shades according to some scalar quantity. We currently

Dear expeRts, first of all I'd like to thank you for the quick help on my last which() problem. Here is another one I could not tackle: I have data on an absorption measurement which I want to fit with an voigt profile: fn.1 <- function(p){ for (i1 in ilong){ ff <- f[i1] ex[i1] <- exp(S*n*L*voigt(u,v,ff,p[1],p[2],p[3])[[1]]) } sum((t-ex)^2) } out <-

I have a question in R. In directory H:/Delta_angle I have 19 files like this: ALA.delta ASN.delta ASP.delta CYS.delta GLN.delta GLU.delta HIS.delta ILE.delta LEU.delta LYS.delta MET.delta PHE.delta PRO.delta SER.delta THR.delta TRP.delta TYR.delta VAL.delta I want to read these files to 19 data sets in R. All these data sets have "P","AA",index","delta"

Hi, I asked this question 2 years ago, and would like to know if the answer has changed. In S-Plus, I build databases of many large objects. In any given analysis, I only need a few of those objects, but attach'ing the whole database is fine since objects are only read as needed. How can I do the same thing in R, without reading the entire database? One possibility is to treat

hi, did'nt see anything in the archive: map('world',pro='rectangular',para=0) yields a strange artifact (horizontal bar) extending over the whole map at a certain latitude range (approx 65 deg. north), whereas map('world',pro='rectangular',para=180) (which should be the same) does not show the artifact. the artifact shows up in other projections as well,

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

I sent a post to find a clever way to compute a Rolling Average of columns in a matrix and I was given the solution below which I am very pleased with. RollingAverage <- function(x, RollingObs) { cx <- cumsum(x); N <- length(x); Temp <- (cx[RollingObs:N] - c(0, cx[1:(N-RollingObs)]))/RollingObs Output <- array(NA, N) Output[RollingObs:N] <- Temp; Output } The only

Hello, I recall reading a thread months ago on this mailing list about handling very datasets under R, but I can't seem to find it. This has become particularly important recently, because I've been playing with a dataset containing information about every fatal car accident in the U.S. since 1975; in total, the relevant files are about 120 megs. I'd like to load all of these into R

Has anyone achieved a current successful build of R 1.8 or 1.9 or earlier for HPUX Tru 64 OSF 5.1? There is no binary version of R for HPUX Tru 64 OSF 5.1. The R admin manual mentions that the native make fails on "Alpha/OSF (aka Tru 64)" and gnu make must be used instead. There are problems reported with building R versions around 1.4 from 2002 on R-devel, some of which were fixed with

I guess this is more r-devel than r-help. Note, I am just the messenger - I have no idea what the user is trying to model here. arima() crashes R (segfault) with Linux R-2.7.0, Solaris R-2.6.0: *** caught segfault *** address 42400000, cause 'memory not mapped' Traceback: 1: .Call(R_getQ0, phi, theta) 2: makeARIMA(trarma[[1]], trarma[[2]], Delta, kappa) 3: arima(x, c(1, 0, 1), c(1,

Hi all, I would like to use R in order to generate a Heatmap/Choropleth overlaid on the UK map. Can someone please help with finding the right package/code? Any help is much appreciated. Best, Reza [[alternative HTML version deleted]]

If .../<pkg>/man/ contains a filename beginning with [, such as [.datetimes, Rdconvlib.pl cannot convert that help file into latex at INSTALL time.

I haven't been able to get anywhere tracking this down. It seems that c.noquote() does something strange with its third (and subsequent) parameters: R-2.7.0 under NetBSD, R-2.6.0 under Solaris, and R-2.8.0 (unstable) (2008-06-10 r45893) under WinXP, I get: > c(noquote('z'), 'y', 'x', '*') [1] z y x * x * > or: > c(noquote('z'),

Is this a bug? Certainly it was not expected. dump() seems to prefer a global definition over a local one. R 1.6.1 on Solaris 8 or NetBSD: > ls() character(0) > dump("D", "D.q") # a global D() exists > system("cat D.q") "D" <- function (expr, name) .Internal(D(expr, name)) > D <- function(x) print(x) # now create a local one > ls()
