Hi I am very new to R and statistical programming in general. I am trying to reorder data from a .csv file. I have managed to import the data and create a zero matrix. I am now trying to fill the matrix. There seems to be some problem with this section of my code. I have highlighted the dodgy code in red. Please help if possible. ###################################################### ###########

hi guys: is there any passes or compiling options that can aviod to generate vector instructions and 'select' instruction in IR. i think that these instructions can be replaced with other instructions in LLVM IR. So if there is a way to eliminate these instructions during compilation? -- View this message in context:

hi Sam: thank you for your reply. but i have another question about this 'select' instruction. i think that in LLVM IR, i can use a branch and two seperate assignments to replace 'select' instruction(am i right?). so is there any compiling option to aviod generate 'select' instruction? -- View this message in context:

Have 4 harddrives hde,hdg etc all of these drives are mounted in samba. When i copy file from one drive to another i notice that server sends the file to my computer and then back to itself (into the right place).

I'm experiencing some weird printing problems with samba connected printers. When I'll bring up a 95/98 workstation, sometimes it will say that the printer is offline, when it clearly isn't, or it will see everything fine, but it simply won't print. These are remote lpd connected printer to the samba server, and lpd can print fine. These are JetDirect HP printers. Any

I have read in several places that one should attempt to avoid for loops whenever possible. In this spirit, I was playing with some code that I have written to improve its efficiency and elegance. The following iteratively drops a column from a data frame and applies a function to the reminaing columns. I replaced this for loop: for (y in 1:dim(x)[2]) my.function (x[,-y]) with this:

I have a data.frame with ~250 observations (rows) in each of ~50 categories (columns). I would like to perform t.tests on subsets of observations within each column, with the subsets according to index vectors contained in other columns of the data.frame. My data.frame looks something like this: x<-data.frame(matrix(rnorm(200,mean=5,sd=.5),nrow=20)) colnames(x)<-c("site",

Hi, Suppose, if I create 15 files in my working directory. set.seed(48) lapply(1:15,function(i) {m1 <- matrix(sample(1:20,1686*2,replace=TRUE),nrow=1686,ncol=2); write.table(m1,paste0("file_",i,".txt"),row.names=FALSE,quote=FALSE)}) ?D <-dir() D1 <- D[order(as.numeric(gsub("\\D+","",D)))] D1 ?res <- t(sapply(D1,function(x) {x1<-

Hi, I would like tranform a data.frame which has a structure similar to the: Col1 Col2 Col3 B1 1 0.3 B1 2 0.4 B1 3 0.3 B2 1 0.2 B2 2 0.2 B2 5 0.4 B2 6 0.1 B3 1 0.2 B3 2 0.1 B3 5 0.2 [Data Frame 1] Into the following structure (pivoting or transpose is being used sometimes to

I have observed the following differences in the use of min/max functions between R and Splus (4.5) R (0.64.1): min(c(NA,NA,NA),na.rm=T) returns the following Warning in min(..., na.rm = na.rm) : no finite arguments to min/max; returning extreme. [1] 2147483647 S-Plus 4.5( Win32 edition) min(c(NA,NA,NA),na.rm=T) returns [1] NA The S-PLUS behaviour seems to be the right one Thanks,
