I see some code in R to attach finalizers to external pointer references (Register[C]Finalizer). Anyone have an example of how to code the finalizer? R_RegisterCFinalizer accepts a C function, but I can't see how to get it to operate on the pointer, since the pointer is not passed to the function when its called. RegisterFinalizer takes an R closure, but how is it called from R (tried

I'm trying to insert rows of a data.frame into a database table, or update where the key fields of a record already exist in the table. I've come up with a possible solution below, but would like to hear if anyone has a better solution. # The problem demonstrated: # Create a data.frame with test values library(RODBC) tbl <- data.frame( key1 = rep(1:3, each = 2), key2 =

I seem to remember something about an "internal" keyword for R doc files. How do we use it? Tim -- Timothy H.

I'm curious if any of the core R developers have considered the possibility of hosting R (v2?) on the parrot common runtime environment. Perl6 will generate byte-code for parrot, as will some future version of python. I can imagine both drawbacks and advantages. Some advantages would be fast byte-code execution and freely mixing perl, python and R modules. Anyone looked into this? Tim

I have an application where I need to preserve object attributes across calls to 'lapply'. The current definition is: lapply <- function (X, FUN, ...) { FUN <- match.fun(FUN) if (!is.list(X)) X <- as.list(X) rval <- .Internal(lapply(X, FUN)) names(rval) <- names(X) return(rval) } Would it make sense to replace names(rval) <- names(X)

Can a C function wrapped with .Call return void? Or must it return a valid SEXP? Thnx. Tim -- Timothy H.

Hi, Thanks for a great environmentfor statistical computing :-) I have some input data in a file ("input_kvpairs.csv") of the form key1=23, key2=67, key3="hello there" key1=7, key2=22, key3="how are you" key1=2, key2=77, key3="nice day, thanks" Now in my head I wish it was of the form ("input.csv") #key1, key2, key3 23, 67, "hello

I'm doing convolutions in the frequency domain and need to know the layout of the Fourier modes returned by fft. (This is leading up to a more involved question about moment generating functions, but I need to know if I've got this part correct first.) I think in 1D the pattern is: 0 1 2 3 -2 1 (even) 0 1 2 3 -3 2 1 (odd) In 2D is it simply (for a square matrix): 0 1 2 -1 (horizontal)

I'm revisiting the R/S DBI package and was wondering if there is any plan to implement package name spaces in R/S. I've taken to the habit of prepending a few characters to function names in packages to avoid collisions, e.g., dbConnect(). An alternative would be DBI::connect() (s/::/preferred/) which in some ways I find more pleasing. Not having thought about it in detail, it seems pretty

Dear R-experts, recently, I started to discover the world of R. I came across a problem, that I was unable to solve by myself (including searches in R-help, etc.) I have a flat table similar to key1 key2 value1 abcd_1 BP 10 abcd_1 BSMP 1A abcd_1 PD 25 abcd_2 BP 20 abcd_3 BP 80 abcd_4 IA 30 abcd_4 PD 70 abcd_4 PS N I wish to transform this table to obtain the following result: key2 key1 BP

Dear R-users I have some trouble to generate more than one key with xyplot using the legend argument. I would like one key with rectangles: library(lattice) library(grid) key1 <- list(rectangles = list(col= c(rev(heat.colors(5))[1:5], rev(heat.colors(5))[4:1])), title="Percentiles", space="right",

Using MultiValueSorter, I can sort by key1, key2, relevance; or relevance, key1, key2. But AFAIK, I can't sort by key1, relevance, key2. Unless I spool out the entire result set or write some C++. I wonder if we need a new 'sort by' function that accepts any combination of keys and relevance in any order? The function would make it's own optimisations (ie is relevance first or

Has anyone used this to get data out of PHP sessions? I can get data out using the php_unserialize function however I am getting a array of strings that looks like this: ["key1: data1","key2: data2"] I would rather get RoR session style of associative arrays ["key1"=>"data", "key2"=>"data2"] Am I just being dense and there is an

Hi everyone, I have the following code that works in data frames taht I would like tow ork in data.tables . However, I'm not really sure how to go about it. I basically have the following names = c("data1", "data2") frame = data.frame(list(key1=as.integer(c(1,2,3,4,5,6)), key2=as.integer(c(1,2,3,2,5,6)),data1 = c(3,3,2,3,5,2), data2= c(3,3,2,3,5,2))) for(i in

Hi, To a large extend, Asterisk's /etc/asterisk/*.conf configuration files conform to a format such as: [section1] key1=value1 key2=value2 [section2] key1=value1 key2=value2 ... To increase coherence when running custom-made application in Perl, Java, PHP, ...) and Asterisk on the same platform, I'm wondering if could extend a bit Asterisk's config files instead of duplicating data

Hi, Asterisk database is made of <family><key> records such as: fam key1 val1 fam key2 val2 ... fam key100 val100 I'm looking for the smartest way to iterate among different keys associated to a given family. One way to do this is to parse "database show fam" response. Is there something smarter ? Something like ${DBKEYS(fam)} which would evaluate to "key1

Buenas, una vez más. Utilizo: data <- subset(data,data$Key %in% data2$Key) para quedarme con los casos de data que están también en data2, de acuerdo a la variable Key. ¿Cómo sería si quiero que sean los que coinciden en Key1 y Key2? Pense hacer un collapse con Key1 y key2, tanto en data como data2, y usarlo como uso key en el ejemplo de arriba, pero debe haber una forma más

Dear R help group I've been working on this plot for a while now and now getting around to the minor adjusments. I would like to be able to put a border and background fill around the legend in this plot. I understand the legend 'bty' should do this have this capablity but not sure how the syntax works in this case ###### initalise library("lattice")
