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

Hello! The Array Programming Languages Conference will be from 24th - 27th July 2000 Please look at: http://stat.cs.tu-berlin.de/APL-Berlin-2000/ Chairman's Address APL Berlin 2000 will take place in a city which is worth a visit even without array processing languages. There is a fortunate coincidence: Much activity in scientific and commercial institutions is based on such languages. Considering this and the ongoing con...

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 effect what in APL was zero index origin, the ordinality of indexes starts with 0 instead o...

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 ftp://ftp.tor.soliton.com/pu...

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 [2,] 5 6 7 8 [3,] 9 10 11 12 > foo[2,,] [,1] [,2] [,3] [,4] [1,] 13 14 15 16 [2,] 17 18 19 20 [3,] 21 22 23 24 flipping foo around its las...

...s (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 http://vgoulet.act.ulaval.ca/pub/R/ The differences were obtained against today's version of r-devel (more specifically revision 30277 of head.R and revision 30915 of head.Rd). Some comments: - The current version...

...tudents how to use the system (S-PLUS, but it could equally well have been R) I can say the most difficult people to teach it to are those you have to "convert" from a long history of expertise in another system. Trying to make R behave like the previous system (SAS, Stata, SPSS, Matlab, APL, ....), as they are invariably determined to do, is ultimately futile, but you, the teacher, find yourself doing all sorts of hand-stands and cartwheels to meet these people half-way. It doesn't work. Trust me. In the end it *really* *doesn't* *work*. Seriously. I'm not sure how we...

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 there a similar operator in R, or is there another/better way? -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-...

And, incidentally, in the opinion of those who have read all three, which of the books, blue, green, or white (or maybe V & R "S programming"?), would be most recommended as the next book for one who would move beyond advanced beginner status?
