Hi, Has anyone had success in building R source with Visual Studio? I followed the instructions in README.packages, but failed on the very first step, where it's looking for R.dll. I looked through R source and couldn't find the file. Can someone point me to where this file is located or generated? Thanks! Sincerely, Jennifer

hello, i want to compute the top k eigenvalues+eigenvectors of a (large) real symmetric matrix. since it doesn't look like any top-level R function does this, i'll call LAPACK from a C shlib and then use .Call. the only LAPACK function i see to do this in R_ext/Lapack.h is dsyevx. however, i know that in LAPACK dsyevr can also return a partial eigendecomposition. why is dsyevr not

I think that this implies that preserving the exact double value in formatC does not follow from C99 standard. Is there some other (e.g. platform specific) documentation that implies this or it has to be used...

...r 'as.character' in R states this in "Details" section. 'as.character' represents real and complex numbers to 15 significant digits (technically the compiler's setting of the ISO C constant 'DBL_DIG', which will be 15 on machines supporting IEC60559 arithmetic according to the C99 standard). This ensures that all the digits in the result will be reliable (and not the result of representation error), but does mean that conversion to character and back to numeric may change the number. If you want to convert numbers to char...

I'm a total newbie at using R, and so there probably is a better way to do this. However, I couldn't find one, and so maybe this will help someone. I was calculating log-likelihoods using a multinomial model, and found that for large n, prod(n:1) wouldn't work to calculate factorials (e.g., prod(200:1) = Inf). The below function calculates the natural log of a factorial (e.g.

Hi, When I run this example code on a G5 the last digit is dropped off on a binary installation of R (R.app), whereas on a linux machine the digit is not removed. # Code: a <- seq(0,1, length=1000)[12] a as.character(a) as.character(as.numeric(as.character(a))) # Results I get: a <- seq(0,1, length=1000)[12] > a [1] 0.01101101 > > as.character(a) [1]

Hi! Does anyone know hot to set number of digits to be printed in function 'paste'? Tine Mla?

Hello, As the author of package cts, I hope somebody on this list can kindly help (perhaps off-list) to resolve the build/check issue with package cts for Mac. The error occurred on Mac machines only: http://cran.r-project.org/web/checks/check_results_cts.html. Here is the error message: At line 10 of file machine.f Fortran runtime error: Range error during floating point read The source

Hello, following functions doesnt work correct with my data: median(), geo.mean(). My datafiles contain more than 10.000 lines and six columns from a flow-cytometer-measurment. I need the arithmetic and geometric mean and median. For the calculation of the geometric mean i wrote following function: fix(geo.mean) function(x) { n<-length(x)

Dear R list, I calculated a two-sided p values according to 2*(1-pnorm(8.104474)), which gives 4.440892e-16. However, it appears to be 5.30E-16 by a colleague and 5.2974E-16 from SAS. I tried to get around with mvtnorm package but it turns out to be using pnorm for univariate case. I should have missed some earlier discussions, but for the moment is there any short answer for a higher

Hello Everyone,   Learning about R and its wonderful array of functions. If it's not obvious, I usually try to find out what a function stands for. I think this helps me remember better.   One function that has me stumped is "sink." Can anyone tell me if this stands for something?   Thanks,   Paul         __________________________________________________ [[alternative HTML
