numeric(0) -> NA
I noticed this in current intermediate patch version: > runif(0,0,4095) numeric(0) > round(runif(0,0,4095)) [1] NA I don't like it, but maybe it is the way it is supposed to be. I would prefer for it to stay numeric(0). I notice also > ceiling(runif(0,0,4095)) numeric(0) > floor(runif(0,0,4095)) numeric(0) which leads me to thing round() is not working right. I have some code

R-beta: is there a way to get rid of loop?
Here is a programming question. The code I am using is quite slow and I was wondering if there is a way to get rid of the for loop. I am dealing with "interaction" in 2x2 table, and am using Edwards's G_I (Likelihood, p. 194). I label the cells in the table as follows stim response "y" "n" total -------------------------------- y hit miss nsignal

[PATCH] exa: add GM10x acceleration support
rendercheck -f a8r8g8b8 passes as much as on a GK208, and xv appears to work. Very lightly tested. Instead of sticking coordinates into pushbufs, the vertex shader is modified to read them from a constbuf, indexed by vertex id. This approach could be used for all nvc0 generations, but I didn't want to rock the boat. Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> --- Note: this

[PATCH] nv10/exa: Spring-cleaning
* Kill the A8+A8 hack. Recent enough X servers (>=1.7) fall back to ARGB glyphs for drivers not supporting A8 render targets. * Kill all the global state. It doesn't matter a lot yet but it might if we get multicard working at some point. * Other random clean-ups with no functional changes. Some numbers from x11perf -aa10text -aa24text -comppixwin10 -comppixwin500: * Before, with A

[PATCH] nv30/exa : cleanup from nv40 exa
This has two purposes : - cleaner code - reduce the diff between nv30 and nv40 exa for a possible nvfx_exa merge ? The main differences seem to be that nv30 uses rect texture format (and does not support repeat on that). Then there are some minor changes in TX_FORMAT RT_FORMAT and TEX_FILTER usage. And NVAccelInitNVx0TCL look complete different. Tested with: ./rendercheck -t

[PATCH v2 0/7] Add Maxwell support
I believe I've addressed all the feedback from the first time around, and also made fixes necessary for GM20x based on testing results. I believe now it should actually work for all GM10x and GM20x. Further, GP10x should be very easy to add, but without someone to actually test I didn't want to claim support for it. Ilia Mirkin (7): exa: add GM10x acceleration support hwdefs: update

R's Spearman
Hi all, I am trying to figure out the formula used by R's Spearman rho (using cor(method="spearman")) because I can't seem to get the same value as by calculating "by hand". Perhaps I'm using "cor" wrong, but I don't know where. Basically, I am running these commands: > y=read.table(file="tmp",header=TRUE,sep="\t") >

Generating DSA keys of different length
When I try to create a dsa set of key files with -b 999, the key appears to be created with the default of 1024. This does not happen for type rsa or rsa1 keys. They get created with the number of bits I specified. I can't find this problem in the archives.

[LLVMdev] Clang/llvm performance tests on FreeBSD 10.0-CURRENT
Hi all, I recently performed a series of compiler performance tests on FreeBSD 10.0-CURRENT, particularly comparing gcc 4.2.1 and gcc 4.7.1 against clang 3.1 and clang 3.2. The attached text file[1] contains more information about the tests, some semi-cooked performance data, and my conclusions. Any errors and omissions are also my fault, so if you notice them, please let me know. The

coalesce columns within a data frame
Dear all, I searched the mail archives and the R site and found no guidance (tried "merge", "cbind" and terms like "coalesce" with no success). There surely is a way to coalesce (like in SQL) columns in a dataframe, right? For example, I would like to go from a dataframe with two columns to one with only one as follows: From Name.x Name.y nx1 ny1 nx2 NA

Discrepancy: R sum() VS C or Fortran sum
Hi all, I found a discrepancy between the sum() in R and either a sum done in C or Fortran for vector of just 5 elements. The difference is very small, but this is a very small part of a much larger numerical problem in which first and second derivatives are computed numerically. This is part of a numerical method course I am teaching in which I want to compare speeds of R versus Fortran (We

help with legacy R code
Hi there, Could somebody help me disect this legacy R script I inherited at work, I have two questions: 1. I've tried to upgrade our R version from 1.6.2 (yeah, I know), to R 2.0, but some of the lines in this script are not compatible with R 2.0, could someone help me figure out where the problem is? 2. the jpeg generated (attached) seems to be off on some of the data, is there a better way
