similar to: Fwd: DLLs

I am trying to write a dynamic linked library for R, in Pascal. (This is to speed up the execution of a simulation that I am running in R.) I know Pascal might not be the perfect language for this (C or Fortran being more natural), but from what I have read I think it should work. Though I should point out that I am a neophyte when it comes to DLLs. From R I want to hand a function in

Hi, all According to the document "LLVM Alias Analysis Infrastructure", I evaluated the AA performance by using the paramenters '-basicaa -ds-aa -anders-aa'. The source code 'test.c' is listed as follow: //------------=== Source code ===------------// #include<stdlib.h> typedef struct { int x; int y; } Location; Location* getNewLocation(int x, int y) {

Dear R community, I have a data set like the following: probe_name chr_id position array1 array2 array3 array4 array5 array6 array7 1 C-3AAAA 10 16566949 10 10 10 10 10 10 10 2 C-3AAAB 17 33478940 10 10 10 10 10 10 10 3 C-3AAAC 3 187369224 10 10 2 10 10 1 10 4 C-3AAAD 8 28375041 10

Hi, I need to do several matrix multiplications with the corresponding matrices forming two 3-dimentional arrays. To illustrate my problem, let's say I have the following 3-dimensional arrays: array1 <- array(1:30,dim=c(3,2,5)) array2 <- array(1:20,dim=c(2,2,5)) I know that I can get what I want with the following computation : result <- array(dim=c(dim(array1)[1],

Dear, I would like to post the following question to the r-help on Nabble (thanks in advance for the attention, Gustavo Vieira): Hi there. I have a data set on hands with 5,220 cases and I'd like to automate some procedures (but I have almost no programming knowledge). The data has some continuous variables that are grouped by 2 others: the name of species and the locality where they were

Dear Jim and Henrique, thank you both for your help. I have done this but run into another problem: ? In the example?below "loc1,loc2" occurs in the (now correct, thanks to your advice) "list" twice. ? ? trips=("loc1,loc2","loc2,loc3") ? DF$listoftrips=("loc1,loc2", "loc1,loc3", "loc2,loc3","loc1,loc2"). ? I?am

No segfault but a BIG warning from the compiler. That's because dereferencing the pointer inside your myfunc() function will produce an int that is not predictable i.e. it is system-dependent. Its value will depend on sizeof(long int) (which is not guaranteed to be 8) and on the endianness of the system. Also if the pointer you pass in the call to the function is an array of long ints, then

Thanks for the replies and for confirming my suspicion. Interestingly, src/include/S.h uses a trick: ?? #define longint int and so does the nlme package (within src/init.c).

Dear R-help community, I have 2 different arrays of precipitation data each of the same dimensions of [longitude, latitude, time] dim=[30,32,43], called array1 and array2. I need to correlate them. This is the code I used to get one overall correlation value for the whole of the area of interest: > result <- cor(array1,array2,use="complete.obs") > result This give me a

I have two large arrays of strings array1 with 180000 names and array2 with 24000 names ,I want to find the common names in both of them. My arrays are for example Array1 Array2 GAP4 HIST1B-histamine.... MFG12 SNRPD-signal induced... CFH1A

Hello, I have two data frames, X and Y, with two columns each and different numbers of rows. # creation of data frame X Loc1.alleles <- c(1,5,6,7,8) Loc1.Freq <- c(0.35, 0.15, 0.05, 0.10, 0.35) Loc1 <- cbind( Loc1.alleles,Loc1.Freq) X <- data.frame(Loc1) #creation of data frame Y Loc2.alleles <- c(1,4,6,8) Loc2.Freq <- c(0.35, 0.35,

dear R users, please, consider the following code you may run: setClass("my.class1", representation( my.list = "list", my.array1 = "array"), prototype=prototype( my.list =list(), my.array1 =array(0,c(3,3,3)) )) #------------------

Dear list, ? I am using match() to match pairs of locations, e.g. trip="loc1,loc2" from a list of such pairs, e.g. list=("loc1,loc2", "loc1,loc3", "loc2,loc3","loc2,loc1"). ? In this example match() will match "trip" with the first element of "list", but not the 4th, because the order is reversed. ? How can I get a match with

Hai, If the primary domain is set in windows, which is after domain join, it used that. Ipconfig /all and see primary DNS suffix. The dns suffix and first dns search list should be the same. Yes, other settings are possible, but stick to this for now. The Primay DNS suffix is used for the register of the IP in the DNS. The DHCP Service User MUST be a member of the DNSAdmins. The DHCP

Hi In my R package, imagine I have a C function defined: ?? void myfunc(int *x) { ????? // some code ?? } but when I call it, I pass it a pointer to a longint instead of a pointer to an int. Could this practice potentially result in a segfault? Regards Ben
