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 all. I've been lurking and posting on this list for a few years now. Prior to that, I managed the US Convertible Arbitrage portfolio for Amaranth Advisors. I recently agreed to manage a similar portfolio for a different hedge fund and am looking for someone to join me, essentially as the principal quant for a new San Francisco office. I've been very impressed with the posters on

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.

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 all: Why arbitrage rarely works. Peter Dalgaard's "Introductory Statistics with R" sells on AMAZON U.S. website at USD 44.95 and on AMAZON U.K at GBP 21.00. At the current exchange rate, the U.K. price translates to USD 32.68, a 27% savings BUT for delivery: the U.S. AMAZON promises 6-10 days whereas in the U.K. 4-6 weeks is promised. At Springer http://www.springer.de the

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

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

I'm an old APL fossil and I got used to work with nested arrays there. In APL(2) you can write 1+(1 2 3)(4 5 6 7 8 9) and get (2 3 4)(5 6 7 8 9 10). A similar concept is R's lists. So it takes me by surprise to learn that 1+list(1:3,4:9) delivers an Error in 1 + list(1:3, 4:9) : non-numeric argument to binary operator Is there any particular reason why this doesn't work

For me as a beginner a cookbook would be welcome. so many great code examples are posted into the help list, but finding these is quite difficult. I think it comes all down to the problem who is compiling / contributing and can judge what should go in. In this respect, Detlef Steuer (suggestion , might be a solution http://fawn.unibw-hamburg.de/cgi-bin/Rwiki.pl?RwikiHome. Frank >

I think the thing that is missing is a simple way for end users on windows to replace blas/lapack libraries with MKL-a package that you install that puts the libraries in the right place. Microsoft provides something for their distro, but we don't have the equivalent if you get R from cran. On 29 October 2017 at 22:01, Kenny Bell wrote: | User here: incorporating Intel's MKL, as MRO

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

At the APL conference in Berlin on July 24 I am giving a talk about about a molecule-like notation for arrays for which some prototype code is available in R. It is a graphical notation for arrays of higher rank which makes the structure of arrays and their various concatenations intuitively apparent, and which, in my judgment, would make an excellent interface for array programming languages. I

Hi Is there a way to programmatically tell whether R is running in batch or GUI mode?
