On a Windows 10 machine I have, $ sizeof.long : int 4; otherwise the same as on my Mac. ????? Am I correct that $ sizeof.long = 4 means 4 bytes = 32 bits? log2(.Machine$integer.max)

Making iconv portable?
Hello, All: What would it take to make ?iconv? portable? I ask, because I want to convert accented characters to vanilla ASCII, thereby converting, e.g., ?Ra?l? to ?Raul?, and Milan Bouchet-Valet suggested on R-help that I use 'iconv(x, ?", "ASCII//TRANSLIT?)?. This worked under Windows but failed on Linux and Mac. It?s part of the ?subNonStandardCharacters? function

General expression of a unitary matrix
Hi, all, Does anybody got the most general expression of a unitary matrix? I found one in the book, four entries of the matrix are: (cos\theta) exp(j\alpha); -(sin\theta)exp(j(\alpha-\Omega)); (sin\theta)exp(j(\beta+\Omega)); (cos\theta) exp(j\beta); where "j" is for complex. However, since for any two unitary matrices, their product should also be a unitary matrix. When I

[External] Re: rpois(9, 1e10)
Thanks to Luke and Avi for their comments.? I wrapped "round" around the call to "rnorm" inside my "rpois.".? For "lambda" really big, that "round" won't do anything.? However, it appears to give integers in floating point representation that are larger than .Machine$integer.max.? That sounds very much like what someone would want.?

????? This issue arose for me in simulations to estimate confidence, prediction, and tolerance intervals from glm(., family=poisson) fits embedded in a BMA::bic.glm fit using a simulate.bic.glm function I added to the development version of Ecfun, available at "https://github.com/sbgraves237/Ecfun".?

Michael Graves post
Michael Grave just posted a question about surround conferences. http://www.facebook.com/notes.php?id=564633430#/note.php?note_id=5009726 3908&id=564633430&index=0 I didn't see it posted on the ast-list, what do you think? Does something like this have potential? I'd love to listen in on one of these calls to see how it actually sounds if someone builds a trial

optim(…, method=‘L-BFGS-B’) stops with an error message while violating the lower bound
Hi, Mark et al.: Thanks, Mark. Three comments: 1. Rvmmin was one of the methods I tried after Ravi directed me to optimx. It returned NAs for essentially everything. See my email of this subject stamped 4:43 PM Central time = 21:43 UTC. 2. It would be interesting to know if the current algorithm behind optim and optimx with

power of a matrix
Dear all, I have a population with three age-classes, at time t=0 the population is: n.zero <- c(1,0,0) I have a transition matrix A which denotes "fertility" and "survival": A <- matrix(c(0,1,5, 0.3,0,0, 0,0.5,0), ncol=3, byrow=TRUE) To obtain the population at t=1, I calculate: A %*% n.zero To obtain the population t=2, I calculate: A %*% (A %*% n.zero) ... and so

FDR analyses: minimum number of features
Dear List, We are planning a genotyping study to be analyzed using false discovery rates (FDRs) (See Storey and Tibshirani PNAS 2003; 100:9440-5). I am interested in learning if there is any consensus as to how many features (ie. how many P values) need to be studied before reasonably reliable FDRs can be derived. Does anyone know of a citation where this is discussed? Bill Dupont William D.

compositional data: percent values sum up to 1
again, under another subject: sorry, maybe an all too trivial question. But we have power data from J frequency spectra and to have the same range for the data of all our subjects, we just transformed them into % values, pseudo-code: power[i,j]=power[i,j]/sum(power[i,1:J]) of course, now we have a perfect linear relationship in our x design-matrix, since all power-values for each subject sum up

nlme questions
Dear R users; Ive got two questions concerning nlme library 3.1-65 (running on R 2.2.0 / Win XP Pro). The first one is related to augPred function. Ive been working with a nonlinear mixed model with no problems so far. However, when the parameters of the model are specified in terms of some other covariates, say treatment (i.e. phi1~trt1+trt2, etc) the augPred function give me the following

[External] Re: rpois(9, 1e10)
R uses the C 'int' type for its integer data and that is pretty much universally 32 bit these days. In fact R wont' compile if it is not. That means the range for integer data is the integers in [-2^31, +2^31). It would be good to allow for a larger integer range for R integer objects, and several of us are thinking about how me might get there. But it isn't easy to get right, so
