similar to: Building an R package under Windows NT

I just uploaded two packages to CRAN. shapefiles_0.1.tar.gz - functions to read and write ESRI shapefiles (including dbfs) emme2_0.1.tar.gz - functions to read binary data from an EMME/2 databank data (EMME/2 is a transportation modeling program) Please let me know if you find any bugs or have some suggestions. Thanks. Regards, Benjamin Stabler Transportation Planning Analysis Unit Oregon

I want to run Rcmd BATCH with R_DEFAULT_PACKAGE=base so it doesn't load any packages, but it seems to reject this argument because it does not start with a '-' or '--'. Is there a different argument that will work? Thanks.

I am trying to build a simple dll with Rcmd SHLIB to link into R. The results of the build are below. From my limited knowledge of building DLLs, it looks like it worked (I didn't get any errors). F:\R\dlls> Rcmd SHLIB add.C making add.d from add.C g++ -IC:/PROGRA~1/R/src/include -Wall -O2 -c add.C -o add.o ar cr add.a *.o ranlib add.a g++ --shared -s -o add.dll add.def add.a

I would like to reference array dimensions by name in an apply and a summary function. For example: apply(x, "workers", sum) Is there a better way to do this than creating a new attribute for the array and then creating new methods for apply and summary? I don't want to name the individual elements of each dimension (such as with dimnames) but rather name the dimensions. Thanks

I understand how R treats NAs but in the situation below it would be nice to have a na.skip argument to paste so it does not convert the NAs to "NA"s and simply skips those elements of the vector for pasting. > x [1] "2.13" "2.3" NA NA "2.83" NA > paste(x, "0", sep="") [1] "2.130" "2.30"

I am trying to figure out R data types and/or storage mode. For example: > #From a clean workspace > gc() used (Mb) gc trigger (Mb) Ncells 415227 11.1 597831 16 Vcells 103533 0.8 786432 6 > x <- seq(0,100000,1) > is.integer(x) [1] FALSE > is.double(x) [1] TRUE > object.size(x) [1] 800036 > gc() used (Mb) gc trigger (Mb) Ncells 415247

R Help- I have a list of 102 vectors all of the same type and length called time.by.orig. I can't data.frame(time.by.orig) but I can data.frame(time.by.orig[1:length(time.by.orig)]). Why is this? Thanks for your help. str(time.by.orig) List of 102 $ 1 : num [1:102] 1.34 17.39 14.36 14.22 7.56 ... $ 2 : num [1:102] 17.5 0.7 17.7 12.4 10.4 ... $ 3 : num [1:102] 14.063 17.568

I am trying to open an existing binary file, seek to a position in the middle, and then write one byte, while keeping the already existing data after that byte. It seems to me that I am unable to open a connection to a binary file in both read and write mode. I can open the "r+b" binary file connection and seek around, but I can't write to the file. And looking at the function

I upgraded to R Gui 1.6 this morning and I can't seem to get it to accept my new startup directory. R 1.51 will accept "F:\_ben\bls\gen1\results\bls\analysis" as the start in directory for the R Gui shortcut, but R 1.6 will not. R 1.6 will accept "F:\_ben\bls\gen1\results\bls". It seems to have trouble when I add "\analysis." R still loads fine but I get the

I put a copy of R 1.8.1 for Windows on our FTP site at: ftp://ftp.odot.state.or.us/outgoing/Test/. It should be there for a few days before it gets deleted.

Hola! I am using Rcmd build --binary ... on a windows XP system, and am encountering a strange problem. Rcmd claims there are syntax errors in one of mine .Rd files ******* Syntax error: mismatched or missing brackets in I take "brackets" to mean [], and I have none of them in the file, and don't think they are needed. Rcmd prints out the offending file, and in the printout I

I am familiar with the rpart and tree packages for classification and regression trees. However, quite a bit of the research in the transportation community relating to decision trees uses the C4.5 family of algorithms by Quinlan. Are there any plans to make a C4.5 (or a derivative of it) available to R? If not, then I might use the WEKA Java package ( http://www.cs.waikato.ac.nz/ml/weka) that

Hi I have a 3 x 2 contingency table: 10 20 30 40 50 60 I want to update the frequencies to new marginal totals: 100 130 40 80 110 I want to use the ipf (iterative proportional fitting) function which is apparently in the cat package. Can somebody please advice me how to input this data and invoke ipf in R to obtain an updated contingency table? Thanks. By the way I am quite new to R. -- Dr

Dear R user, I am running R under Windows 2000. I am looking for a routine for importing - shape files (ESRI) into R - dbase files (FOXPRO) into R and I am looking for time-space models for description and prediction of Bernoulli-, Binomial- and Poissonvaraibles. Thank's a lot for a reply. Sincerely yours, Ekkehardt Altpeter Swiss Federal Office of Public

i am new to R,so i post here to ask you how to learn R quickly? is there some usefull materials about using R. ps:though the manual is a good materials,but it is not the best for a newbie,i think. thank you !

Can someone tell me how to make up (eg) a library's html help files by hand? I think I ought to be able to use RCMD Rdconv for this but (R-2.10.0, MS-win) when I type (in a dos session) "rdcmd rdconv --help" I get a message to the effect that a perl script rdconv can't be opened. Can I do this from within R itself? And if so, how (in particular, what is the target file to

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>>)}

I am trying to multiply a 3D array of 4x4x4 by the 4 3D arrays of a 4D array with dimensions 4x4x4x4 (the last dimension being the one that I want to split by).

Hi all, I am currently building an application based on R 1.7.1 (+ compiled C/C++ code + MySql + VB). I am building this application to work on 2 different platforms (Windows XP Professional (500mb memory) and Windows NT 4.0 with service pack 6 (1gb memory)). This is a very memory intensive application performing sophisticated operations on "large" matrices (typically 5000x1500

Dear R People I have a function that I wrote. It's not part of a library, it's just a nice function. However, I would like to have a "Help" page for it. How do I go about doing that please?
