Hi, is there a function in R to convert data read with read.shape and which is originally in UTM coordinates into longitude / latitude coordinates? I found the convUL() function from the PBSmapping package but I have no idea how I could apply that to the read.shape object. Many thanks, Werner __________________________________________________ Do sragenden Schutz gegen Massenmails.

Hi, this is probably the easiest thing to do but I manage not finding the answer: I have a list with matrices of exact same format and headers. Now I would like to transform the list into an normal array. What is the proper way to do this? as.array changes the entire format and right now I only found the method of creating a new array, going through the entire list and copy the matrix in each

Hi! I have large matrices, one column per variable and I have a vector of factors / grouping symbols. Then I am computing subtotals for the groups but it takes pretty long and thus I wanted to ask if there is a better way to do it or if this is already the best way: subTotals <- function(x, groupvec) do.call("rbind",lapply(split(x,groupvec),colSums,na.rm=T)) Thanks reading my

Hi, Before I reinvent the wheel I wanted to kindly ask you for your opinion if there is a simple way to do it. I want to merge a larger number of tables from different data sources in R and the matching criterium are country names. The tables are of different size and sometimes the country names do differ slightly. Has anyone done this or any recommendation on what commands I

Hi, I was wondering if anybody might have a reference for me: My R code is growing and getting more and more confusing. Thus, I figure it's time to switch to object-oriented again. I have done oo programming in C++ and Java before but the first few tutorial on R oo were a bit confusing for me. Is there any brief tutorial on oo programming in R especially for people who have done oo in Java

Hi, I have two loosely related questions which could make my live again a bit easier: 1) Is there a simple way to select a range of columns in a data frame using column names? I am thinking of something like mydf[1,"col4":"col8"] 2) I have a data frame with many columns and they all have short variable names which is good in most cases but sometimes it would be nice to have

Hi there! I am considering to port a SAS application to R and I would like to hear your opinion if you think this is possible and worthwhile. SAS is mainly used to do data management and then to do some aggregations and simple computations on the data and to output a modified data set. The main problem I see is the size of the data file. As I have no access to SAS yet I cannot give real details

Hello, I am very happy that I have Sweave and R to write my papers. But I still have to do some tables by hand since I have not found out how I can customize the latex tables produced by R further (I mainly use xtable()). Like for instance, I have a table which needs an extra row every few rows as a group header and sometimes I want some extra horizontal lines in the table and also a multicolumn

Hi, I am using Tinn-R and somehow I cannot point it to start a R shortcut with http_proxy settings including authentification. It always shows the .exe. Is there any way to set the proxy from within R or any other ideas how to do it? I am using R 2.4 for Windows. Thanks a million, Werner

Hi, this is probably a very trivial question but I can't figure out the right terms to find the solution in the list archive. I have a matrix or a data.frame or the like: > m <- matrix(ncol=3,seq(1,9)) > m [,1] [,2] [,3] [1,] 1 4 7 [2,] 2 5 8 [3,] 3 6 9 and now I wonder if one can provide somehow two vectors, one containing row numbers, the other

Hi, since I have quite large tables and the processing takes quite a while I am curious if I can improve the performance of this aggregation somehow: At the moment I am using summaryBy from the doBy package under R 2.4.0, Win2K. summaryBy(soc_s6aq5 + soc_s6aq7 + soc_s6aq9 + soc_s6aq11 ~ hh + comgroup,soc6a,postfix=c("","","",""),FUN=sum, na.rm=T) The

Hi, I have loaded the packages car, memisc, Hmisc and all of these implement the function recode. The order in which the packages are loaded depends on the order I execute my scripts and thus is not always the same and the syntax of the recode function changes with the package. Is there any way to call specificly the memisc recode function? Or maybe it's better to detach all packages first

Does anyone have an R Syntax Highlighting file {userDefineLang.xml} for NotePad++?? I've started one, but I'm not so happy with it.

Hi, I have adviced my students to install R and an editor on a USB drive for working in the computer class. With R everything works fine following these instructions: http://personal.bgsu.edu/~mrizzo/Rmisc/usbR.htm. But several editors (e.g., Tinn-R and WinEdt) require administrator rights. I have found out that Emacs (Vincent Goulet's Emacs for Windows Modified

Dear all, can somebody please update me on what could be the best editor to write and edit the RD files? I need to something with syntax highlighter, auto-completion etc (like Notepad++ for R etc.). Currently I am using plain Notepad however expect something which could be more professional. Thanks for your help. [[alternative HTML version deleted]]

Hi! I have browsed the help archives but did not find anything on the subject: How to make publication quality graphs with R best? Is there some document about that topic out there? The problem is that the graphs look nice on the screen but when printed in black and white every color apart from black doesn't look very nice. Is there some guideline how to set color palettes and or fill

Hi, has anybody encountered and solved the following problem? I continued work now on a different computer where I have also used Sweave successfully before. I can run Sweave() and it generates a .tex file. All code chunks are processed and translated to Latex perfectly fine but somehow only the \Sexpr{} tags are not parsed. This is an example .Rnw: \documentclass{article} \usepackage{Sweave}

Hi, sqldf sounds like a very useful package but I don't even get the example to run: > a1s <- sqldf("select * from warpbreaks limit 6") Error in combine(FUN(...)) : argument "value" is missing, with no default > I am using R 2.6.1 on Windows Vista Business and have updated all packages. Some help would be very much appreciated. Many thanks, Werner

Hi, I would like to read in multi-dimensional data from a text file, i.e. "tables" with more than 2 dimensions. I have looked for a function which I can abuse for that but haven't found anything. I would appreciate it a lot if somebody gave me a hint if such functions already exist somewhere. Thanks, Werner

Hi, I am very intrigued by the idea of integrating statistical analysis directly with a paper as Sweave does it. But as I am collaborating with several people and they won't have set up R and also they're very unlikely interested in learning it, I am concerned about how such an Latex/Sweave document will work on their side. Can they Latex-compile the document without having R / Sweave
