Do you know if you can map in R? I have my minimum spanning tree, but as there are 1371 nodes (all over Australia) I'd like to be able to "graph" them as they actually would be on the map. Do you know if this is possible?

I've written the function below to simulate the mean 1st through nth nearest neighbor distances for a random spatial pattern using the functions nndist() and runifpoint() from spatsat. It works, but runs relatively slowly - would appreciate suggestions on how to speed up this function. Thanks. --Dale library(spatstat) sim.nth.mdist <- function(nth,nsim) { D <- matrix(ncol=nth,

Hello all, I wish to compare two dendrograms (representing Hierarchical Clusterings). My problems are several: 1) how do I manually create a dendrogram object ? That is, how can I reconstruct it as an "hclust" object that creates such a dendrogram, when all I have is the dendrogram image (but don't have the underlaying distance matrix that produced it) ? I see that there is a

R-Help Please can you tell me if there is a function within R that will return the day of any given date? Using 19 March 2006 as an example: given 20060319 (or any other date format) will return the day Sunday. Many thanks Fiona.

Dear All At institutes where there are PC labs used by Masters and undergraduate students and software is maintained /managed by a central IT services, do you always update R every time a new version is released - around beginning of April and October? Do you also ask them to install all patch releases as they turn up? Currently our IT department update once a year before the start of the Autumn

I've tried to download rw1090.exe 3 times and rw1081.exe once onto a Windows XP from the UK mirrors (I've tried both of them). When the download is complete and I double-click on the icon I get an error message telling me the set-up files are corrupted and to obtain a new copy of the program. I have spent quite a lot of time checking the message archives but I can't find a solution. If

Hi I have just upgraded from R2.6.0 to R2.7.1 (running on Windows) and a part of my code that previously ran ok now gives an error. The following is a simple example to demonstrate my problem. > a <- array(c(1,2,3,4,5,6,rep(NA,6)),dim=c(6,2)) > apply(a,2,sd,na.rm=T) In R2.6.0 this gives (which is what I would like) [1] 1.870829 NA In R2.7.1 it gives the following error

Hi, I've met a problem when I am trying llvm. I've added a small pass in it, and when I define or use an object of APInt class, it will get the following output while running: $ opt -load hello.so -hello test.bc -o test.hello.bc opt: CommandLine Error: Argument 'disable-opt' defined more than once! opt: CommandLine Error: Argument 'disable-inlining' defined more than

Is it possible to create a contour plot with the isolines labeled. I know you can do this with Matlab. Argh! I tried creating a filled contour plot, then using par(new=T), followed by overlaying the contour plot on top. However, the placement of the filled contour plot and the contour plot do not align correctly. Any suggestions would be appreciated. Thanks, Jon -- View this message in

Hi I was wondering if someone could help me with an rpart problem. I can see that cross-validation is the default for tree selection in rpart -- has a bootstrap method been implemented anywhere? I think this is a different thing to 'bagging' or 'boosting' -- I still want 'one' tree at the end, I just would like it chosen using a bootstrap method. Any ideas??? Thanks

I am trying to stream various 320kbps MP3s across my 10Mbps LAN. Either locally or across the network, freeamp and xmms prefetch a chunk, then play it, then fetch another chunk etc. No continuous streaming. shout gets a lot of !s between its "."s when sending the file to icecast. Any ideas? -- Always hardwire the explosives -- Fiona Dexter quoting Monkey, J. Gregory Keyes, Dark

Hi all, Our section at work is looking at buying a high-powered computer (32 Gb RAM, 64-bit) to be able run models on large datasets and have more processing power for the software we commonly use. We mostly use R to fit GLMs and GAMs. Our department uses Windows as the standard OS (we are upgrading to Vista in the next few months) and so most people would be in favour of having the same OS on

Hi all, 1. I am doing some data analysis using both R and SPSS, to get used to both software packages. I had performed linear regression in R and SPSS for a number of times before this last one and the resulting coefficient values always matched. However, this last data set I was analyzing using simple linear regression and using the command lm(y~x), gave me different readings from R and

Hi All, I''m a RoR n00b that has been lurking for a week or so. About two weeks ago I bought the text version of Agile Web Development with Rails. Today, I bought the .pdf version because I run a Sony Notebook and find a .pdf more user friendly. Therefore I have the text to give away for free. If anyone in the continental US would like the copy please let me know and I''ll mail it

I would like to use the map function for the continental US plus Hawaii, but can only find the library files for the continental US. Suggestions? Thank you.

Hello, Rather than rely on a set of IF statements (as there could be many - please see below)), could the following be done in a different/better way? InternalMean <- mean(data1[,3]) if (InternalMean == 0) Intresult = 1 if (InternalMean > 0 & InternalMean < 1) Intresult = .95 if (InternalMean >= 1 & InternalMean < 2) Intresult = .85 if (InternalMean >= 2

I've just had polarity reversal provisioned by our telco to test hangup detect with a TDM400P I've set hanguponpolarityswitch=yes in zapata.conf When I start Asterisk I get "ignoring hanguponpolarityswitch" in /var/log/asterisk/messages I assume that the option is either not valid or conflicts with another setting somewhere. Any ideas?

First of all, thanks to those who've set up R to work so smoothly with Miktex-- even a total Latex bunny like me got it to work instantly, so that for the first time I'm able to run my Rd files through the Latex side of RCMD CHECK. Now the question/buglet. One of my Rd files contains the following: \code{mlazy( <<objname1>>, <<objname2>>, <<etc>>)}
