Dear R-helpers Are there any established R packages that include a C code generator -- that generates new C language files and compiles them? To be precise what I'm looking for is a process that takes text input in some format (it might be pseudocode, fragments of C code, etc) and creates a valid C language source file that can be compiled by R CMD COMPILE. Ideally the procedure should also cause the C code to be compiled and dynamically loaded. To give a trivial example, suppose I want to be able to perform image filtering operations on matri...

Hi group, suppose I have a date, say May 15 2004, and I want to now what date it is 23 days before that date. The way to calculate the new date should (...) take account of leap years :) In pseudocode: olddate <- "May 15 2004" newdate <- olddate-23 I looked around in POSIXct etc..., maybe I overlooked?

...erically access their elements and do something with them. For instance, instead of this: df1<- data.frame(x=(1:5),y=(1:5)); df2<- data.frame(x=(1:5),y=(1:5)); df3<- data.frame(x=(1:5),y=(1:5)); plot(df1$x,df1$y); plot(df2$x,df2$y); plot(df3$x,df3$y); I would like to do something like: (pseudocode) dfarray[1] = df1 dfarray[2] = df2 dfarray[3] = df3 for (each i in dfarray) { plot(i$x, i$y); } Can this be done in R?

Sorry folks but again I have failed in my understanding of how to do a very simple thing. I've read the various texts and searched the help archives but no positive result so far. I want to remove all the rows in a data frame where one of the variables has negative values. In approx Stata pseudocode: drop _all, if( x < 0 ) Please either point me to relevant sections of the docs or supply me with solution - I'm sure it's very simple. Michael

Hi, While playing with quantile-quantile plots, I wrote up some code which plots something strangely different. Here's the pseudocode: testhist <- hist(sample_data) refhist <- hist(rnorm(n, mean=0,sd=1)) # for some large-ish n cumtest <- cumsum(testhist) cumref <- cumsum(refhist) plot(cumref,cumtest) This produces a straight line of slope 1 for a sample with the same parameters as the reference sample, and produc...

So here is a different approach (pseudocode): %a_zext = zext %a to i33 # 1 more bit %b_zext = zext %b to i33 # 1 more bit %result_zext = add %a_zext, %b_zext %max_result = @llvm.experimental.vector.reduce.umax(%result_zext) %overflow = icmp %max_result > @max_i32_value %result = trunc %result_zext to i32 You can imagine how this would w...

Dear R Community, I'm trying to exploit the elegance of R by doing the following pseudocode routine without a WHILE or FOR loop in R: for i = 1 to length-1 for j = (i+1) to length print a[i], a[j] That is, I want i and j to be the indices of a half-matrix 1 2, 1 3, 1 4, ..., 1 length, 2 3, 2 4, ..., 2 length, 3 4, ..., 3 length 1. Can this be done with the 'w...

I don't examine Preston Briggs work so thoroughly.  So I can not say that is true.  Even so it is natural that there are discrepancy in pseudocode and its description especially for such size description. For me Preston Briggs is famous for his introduction of optimistic coloring....

...I need to run this program on a large batch of parameters, such that it would clearly be desirable to automate the process. Is there a straightforward way to do this? I can't find any online documentation addressing this topic, but perhaps I've not been looking in the right place.

A smart way would be storing the calculated matrices in a list inside bsplinegrid. Pseudocode would look like this: bsplinematrix <- function(bsplinegrid, deriv=0) { if (is.null(bsplinegrid$matrices[[deriv+1]])) { ## compute the matrix and put it in the list bsplinegrid$matrices, ## but not of the local copy } bsplinegrid$matrices[[deriv+1]] } My problem is that I don'...

...Problem is though, that the Ruby compiler is integrated in the compilation of the program being executed, to be able to parse & compile dynamic code at run-time. Therefore the calls to ExecutionEngine::getPointerToGlobal(F) need to be made in LLVM code. Here is a detailed simplistic example in pseudocode of what we want to do: First Ruby code is entered at run-time, received as a string, parsed and compiled into the following code: %-------------- ; External function declare int %printf(sbyte*, ...) ; Custom function int %puts_kernel( sbyte* %string ) { %tmp.0 = call int (sbyte*, ...)* %printf(...
