search for: forloops

I have a very simple kernel that is generating very very bad code. The basic kernel pseudo-code is as follows: forloop(1 to n) { forloop(0 to j) { A } B } C It is generating very ugly and inefficient code for a vector system similar to the following pseudo-code: if (n > 1) { if (j) { forloop(1 to n) { forloop(0 to j) {

I'm trying to get a data.restore function to work on functions. One thing I can't figure out: how do you construct a function from it's component parts? For example, I can construct a for loop as forloop <- as.call(list(as.name('for'),as.name('i'),1,as.call(list(as.name('junk'))))) which results in for (i in 1) junk() But how do I put that in a

I have one data frame with a column of dates and I want to fill another data frame with one column of dates, one of years, one of months, one of a unique combination of year and month, and one of days, but R seems to have some problems with this. My initial data frame looks like this (ignore the NAs in the other fields): > mans[1:10,] date loc snow.new prcp tmin snow.dep tmax 1

Hello R Community, I don't post to these things often so excuse me if I stumble on my forum etiquette. This is a complex problem for me, which may require two forum entries, but I will try my best to be concise. Also, I am a self taught coder, so if my code is not to convention, your constructive criticism is always welcome. I need to split up a data frame by participant (gpsarc -

Hi R, Please solve my problem........... I am extracting Bloomberg data from R, in a loop. R is getting fatigued by doing this process and gives some errors. I introduced sleep function. Doing this sometimes I get the results and sometimes not. I even noticed that if I give complete rest for R (don't open R window) for 1 day and then run my code with the sleep function, then the

Here's a small R program: --------------------------------------------------------------------------- a <- rep(1,10000000) system.time(a <- a + 1) system.time(for (i in 1:10000000) {a[i] <- a[i] + 1}) --------------------------------------------------------------------------- and here's its matlab version:

...Sweave, I generate tex code straight from R for dynamically computed reports. If I do this in R: for (i in 0:4) {cat("\n",i,"\n")};cat("\n 3") 0 1 2 3 4 3 The output looks correct. However, Sweave for some reason seems to trim everything outside forloops. Hence, this <<results=tex,echo=FALSE>>= sec<-0 lambda<-0 chartvalue<-"b" relsec<-0 for (chartvalue in c("b","beta")) { for (relsec in 0:(e("count pd")-2)) { file<-paste("working/frontfile",sec,"x&quot...

Here is that patch. Btw, I've just been using bugpoint, and it's really nifty! --Sean Silva 2012/2/27 Rotem, Nadav <nadav.rotem at intel.com> > Sean, > > Thanks for looking at this.

Sean, Thanks for looking at this. Knowing that the last instruction triggered the bug is often not enough. I use bugpoint to reduce the failing test. The reason is that some of the bugs may be caused by the interaction between several instruction. Having said that, I think that the change that you proposed is a good one. Can you send a patch ? Thanks, Nadav From: Sean Silva

How about a less massive and complicated scheme? I think we can make

Hi R people! I have a directory of .csv files I would like to make into objects then scatter plots. I have been having varying degrees of progress. I was able make an object of all files, loop through it, and make a pdf of the last file I looped through. I kept renaming the pdf so instead of ending up with 27 pdfs I got one, with the data from the last file I have been tweaking with it
