Hi, When R generates density plots and these are exported to postscript( a=matrix(1:100,10,10);image(a,col=rainbow(100);dev.copy2eps(file="image.eps") ) The result often looks bad when rendered on screen. The help page states that this is because programs use anti-aliasing. That seems to be true - turning off anti-aliasing for gs (-dGraphicsAlphaBits=1) of in OSX's preview makes

Dear R users -- I think this question was asked before but there was no reply to it. I would appreciate any suggestion any of you might have. I am interested in plotting several "implicit functions" (F(x,y,z)=0) on the same fig. Is there anyone who has an example code of how to do this? Thank you Yihsu

Hello, I am dealing with numeric vectors 10^5 to 10^6 elements long. The values are sorted (with duplicates) in the vector (v). I am obtaining the length of vectors such as (v < c) or (v > c1 & v < c2), where c, c1, c2 are some scalar variables. What is the most efficient way to do this? I am using sum(v < c) since TRUE's are 1's and FALSE's are 0's. This

Dear All, I am using fexact.c on a C++ program I wrote. To minimize dependencies on other files (e.g., to not need to include R.h and ctest.h ---now I only include the R files Boolean.h, Constants.h, and Memory.h), I have re-written all declarations of Sints as ints and, what is potentially more serious, I have re-written the line (lines 329 and 330, in fexact.c on R-1.6.1) /* IMAX is the

I've noticed that LLVM does a bad job of optimizing array indexing code for FORTRAN arrays declared using the ALLOCATABLE keyword. For example if you have something like the following: DOUBLE PRECISION,ALLOCATABLE,DIMENSION(:,:,:,:) :: QAV ... ALLOCATE( QAV( -2:IMAX+2,-2:JMAX+2,-2:KMAX+2,ND) ) ... DO L = 1, 5 DO K = K1, K2 DO J = J1, J2 DO I = I1, I2 II = I +

Hi everyone! I already posted http://r.789695.n4.nabble.com/Declaring-a-density-function-with-for-loop-td4635699.html a question on finding density values of a new Binomial like distribution which has the following pmf: http://r.789695.n4.nabble.com/file/n4636134/kb.png Thank fully http://r.789695.n4.nabble.com/template/NamlServlet.jtp?macro=user_nodes&user=124474 Berend Hasselman and

Duncan, Do a quick check here on x86_64-apple-darwin10 with svn llvm and svn dragon-egg against release gcc 4.5.0, the results from the himenoBMTxpa benchmark compiled at -O3 look pretty good. With stock gcc-4.5.0, we get... Grid-size = M mimax = 128 mjmax = 128 mkmax = 256 imax = 127 jmax = 127 kmax =255 Start rehearsal measurement process. Measure the performance in 3 times. MFLOPS:

Hi, The following distribution is known as Kumaraswamy binomial Distribution. http://r.789695.n4.nabble.com/file/n4636782/kb.png For a given data I need to estimate the paramters (alpha and beta) of this distribution(Known as Kumaraswamy binomial Distribution, A Binomial Like Distribution). For that, in order to use *optim()*, I first declared the Negative Log-likelihood of this distribution as

K-means recluster data with given cluster centers Dear R user, I have several large data sets. Over time additional new data sets will be created. I want to cluster all the data in a similar/ identical way with the k-means algorithm. With the first data set I will find my cluster centers and save the cluster centers to a file [1]. This first data set is huge, it is guarantied that cluster

Hi, We are facing a problem on AIX 5.3 (latest patch) where the following behavior happens. Reproduced with versions of samba from 3.0.23 to 3.0.26a. # Normal behavior : # id and id username should return the same info # root@srv1:/# id uid=0(root) gid=0(system) groups=2(bin),3(sys),7(security),8(cron),10(audit),11(lp) root@srv1:/# id root uid=0(root) gid=0(system)

Hi! Since I started to use Debian kernel 2.6.10 (in unstable), the problem disappeared. Fedora Core 3 uses 2.6.10 too so I don't know

Came across this page... intended to showcase the high-end capabilities of WMV9... http://www.microsoft.com/windows/windowsmedia/content_provider/film/ContentShowcase.aspx Just thought some people might be interested in it to make some comparisons... and it's also probably some of the highest quality sample material i've found on the net... so it's also useful for me to use as

This is probably a trivial question, but I did not see it in the FAQs. Perhaps I simply need to be pointed to some URLs. In any case, I have some sampled data that has peaks, and I would like to extract peak height, location, and width, according to almost any statistical model. Gaussian would seem to make the most sense. There can also be "steps" increasing the amplitude over a

plot.hclust: Setting up a window for a dendrogram assumes the first link is the shortest and the last is the longest. This is not always the case when the clustering was done with hclust, method="median" or method="centroid", and the dendrogram sometimes doesn't fit within the window.

Hello, some misc. cleanup patches for speexdsp, nothing big I'm not sure about how to submit patches, so this is a test balloon :) ultimately, I'd like to fix the FIXED_POINT issue, see http://lists.xiph.org/pipermail/speex-dev/2013-December/008465.html currently, I think the only way to find out how speexdsp has been compiled is to resample some bytes and observe the output; which is
