R-beta: New R Version for Unix
Version 0.60 of R for Unix is now available. Release of this version has been delayed for a variety of reasons, but we hope that it will provide a good deal more stability and functionality than previous versions. However it should be regarded as of "alpha" quality for a short shakedown period. We would like user feedback to help us improve the quality of R. You can do this by

Hedge Fund Job Opening
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

RE: [R] Several R vs S-Plus issues (PR#1112)
Also in assign() there some arguments lacking in R such as 'frame' and 'where', though I guess that 'frame' in S may be similar to 'pos' in R.

[LLVMdev] Alias analysis issue with structs on PPC
Hi, I have the following C loop to vectorize: struct box { double* source; }; void test(double* restrict result, struct box my_struct, int len) { for (int i=0 ; i<len; i++) { result[i] = my_struct.source[i] * my_struct.source[i]; } } There are two references in the loop, result[i] (restrict) and my_struct.source[i] (readonly). The compiler should easily figure out that

Dalgaard's book
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.

unlist errors on a nested list of empty lists
I do not have access to the bug reporting system. If somebody can get me access, I can create a formal bug report. The latter issues seem like duplicates of: https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=12572 (with slightly different output), but as that bug was reported nearly 10 years ago, it might be worth creating an update under R version 3. I could not find the first issue when

data() misbehaving inside a function
Calls of the form data(package = pkg) inside a function incorrectly fail ("pkg" is a local variable). For instance, foo <- function(pkg) data(package = pkg) foo("base") Error in .find.package(package, lib.loc, verbose = verbose) : none of the packages were found ## workaround -- force argument "package" to be an expression ## (not a

[LLVMdev] llc is taking a long time at -O1 to convert *.bc to *.s
Hi All, I am using llvm-3.0 release version for compiling some files. I have a cpp file on which I did a few custom passes. After that I used llc to convert the *.bc file to *.s file at -O1 optimization level. llc took ~2630 seconds to perform this conversion. I timed llc and these are the top three passes that is taking most of the time. ---User Time--- --System Time-- --User+System--

Characters subsetted with NA (was: Several R vs S-Plus issues)
Hello, R-devel!
