search for: forloop

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 function? For example, I'd like the function function() for (i in 1) junk() but as.function(list(forloop)) result...

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

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
