http://idisk.mac.com/jdeleeuw-Public/utilities/apl/apl.R Dedicated to the IBM 2741. Implemented for general multidimensional arrays: drop, take, reshape, shape, rank, select, generalized inner product, generalized outer product, representation, base value, join, expand, reduce, scan, member of, ravel, compress, tranpose, rotate Basically, the APL-I part is complete, and after some testing

Hi, is anybody out there who knows APL and would help me to translate 52 lines of APL code into propper R? best, Torsten

I'm very new to R and utterly blown away by not only the language but the unbelievable set of packages and the documentation and the documentation standards and... I was an early APL user and never lost my love for it and in R I find most of the essential things I loved about APL except for one thing. At this early stage of my learning I can't yet determine if there is a way to

nowhere does it say that centos is approved for use in DoD. it is not on the APL, only RedHat and SuSE

Hi, I have mentioned before that we have added some sdt dtrace probes in SAX, our APL interpreter. Encouraged by Angelo and Jignesh, I have created a small document (5 pages) describing our experience with it, together with some problems we have encountered and some scripts we use for pretty-printing dtrace outputs. The said document can be found at

Hi everyone I've been playing with do.call() but I'm having problems understanding it. I have a list of "n" elements, each one of which is "d" dimensional [actually an n-by-n-by ... by-n array]. Neither n nor d is known in advance. I want to bind the elements together in a higher-dimensional array. Toy example follows with d=n=3. f <-

Hello people, Is there some simple way of spinning and/or flipping arrays in R? Here's what I mean. Suppose that foo is a 2x3x4 array with the following contents: (I know this is different than typing 'foo' at and R prompt, but I'm so used to row major order from using APL, I have a hard time with R's output) > foo[1,,] [,1] [,2] [,3] [,4] [1,] 1 2 3 4

Dear developeRs (and other abuseRs ;-), I would like to contribute a patch against functions head() and tail() of package utils to allow for a negative 'n' argument. This allows to extract all but the first/last 'n' elements/rows/lines of an object, similar to the "drop" operator of APL. [1] I put the patched head.R and head.Rd files, along with diff files in

I'd like my compiler to emit proper line number information. The docs talk about Instruction::setDebugLoc(), but that method doesn't actually have to be in my 2.7 LLVM Debian package. What's the correct way of doing this? In addition, can anyone point me at an example of how to emit a comment attached to an instruction (or function)? -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ─────

Dear r-users, Suppose I have three datasets: Dataset-1: Date x y Jan-1,2005 120 230 Jan-2,2005 123 -125 Jan-3,2005 -110 300 Jan-4,2005 114 -21 Jan-7,2005 11 299 Mar-5,2005 200 311 Dataset-2: Date x y Jan-2,2005 123 -125 Jan-3,2005 -110 300 Jan-4,2005 114 -21

Given a structure like this (using C syntax rather than LLVM because I'm still not fluent with LLVM assembly): struct Object { int i1; int i2; int i3; }; Then, if I have an int* pointer which I know is pointing to the i3 element, what's the best way of recovering a pointer to the structure as a whole? My fallback option is to cast the pointer to an int64, use getelementptr to

I see Thomas has already nailed this one, so it becomes a non-issue. Nevertheless I feel moved to say I think the idea would have been a step in the wrong direction in the first place. It comes from a desire to make R behave "a bit more like matlab" and that is ultimately unhelpful. Having tried to teach generations of students how to use the system (S-PLUS, but it could equally well

Given an nxm matrix A I want to compute the nxm matrix B whose ij-th element is the sum of the elements of A lying on the diagonal that ends with element ij, i.e., b_ij = a_ij + a_(i-1)(j-1) + a_(i-2)(j-2) + ... In APL (which I no longer use), I would use the 'rotate' operator to derive an array whose columns are diagonals of the given array and then cumulate down columns. Is

I bogged down about half way through reading the Green Book, in part because it became increasingly difficult to understand how some of the ideas related to R, as opposed to S (which I have not used). Does any reader know whether there is a document that points out differences between S and R that would be helpful in reading the Green Book? Ideally, perhaps, I need a "crib sheet" to
