similar to: sum() returns 0 not NA

Dear all! I'd like to do multiple imputation of missing values with s-plus libraries that are provided by Shafer (http://www.stat.psu.edu/~jls/misoftwa.html). I wonder, whether these libraries are compatible or somehow convertible to R (because I don't have S-plus), so that I can use this functions using the R Program. I would be happy if you could tell me, -if it is possible to use

Dear experts, I try not to trouble the list again after this question. I want to print this vector into a file > myvec [1] --Control --Control --Control --Control --Control HBA2 HBA1 [8] HBA1 --Control HBB --Control HBB HBA1 MBP [15] --Control HBA1 HBA2 HBB PTGDS GAPDH UBC [22] --Control GAPDH TPT1 HUWE1 PRM1 CKM

I would like to generate pseudo-random numbers between two numbers using R, up to a given distribution, for instance, rnorm. That is something like rnorm(HowMany,Min,Max,mean,sd) over rnorm(HowMany,mean,sd). I am wondering if dnorm(runif(HowMany, Min, Max), mean, sd) is good. Any idea? Thanks. -james

Dear All, I assume this is an R-devel issue, apologies if I missed something obvious. I have a dataframe where the row names are country codes, based on ISO 3166, something like this: ------------ "v1" "v2" "UK" 1 2 "NA" 2 3 ------------ It happens that "NA" is the country code for "Namibia", and that creates problems on

Hi all! I am new to R and I would like to ask you the following question:How can I substitute the NA values with 0 in a data frame? I cannot find a command to check if a value is NA... Thank you very much! Eleni

Is there any way to "force" 0 * NA to be 0 instead of NA? For example, suppose I have a vector with some valid values, while other values are NA. If I matrix-pre-multiply this by a weight row vector, whose weights that correspond to the NAs are zero, the outcome will still be NA: x <- c(1, NA, 1) wt <- c(2, 0, 1) wt %*% x # NA Alberto Monteiro

Hi Folks, Given a series of n independent Bernoulli trials with outcomes Yi (i=1...n) and Prob[Yi = 1] = Pi, I want P = Prob[sum(Yi) = r] (r = 0,1,...,n) I can certainly find a way to do it: Let p be the vector c(P1,P2,...,Pn). The cases r=0 and r=n are trivial (and also are exceptions for the following routine). For a given value of r in (1:(n-1)), library(combinat) Set <- (1:n)

Dear All, Could someone please suggest how to find the Kronecker sum of two 2x2 matrices, i.e. given two matrices: -A A a -a and -B B b -b I need: -A-B A B 0 a -a-B 0 B b 0 -A-b A 0 b a -a-b Many thanks, Lara [[alternative HTML version deleted]]

Samba List: Is anyone out there using AutoCAD R14 and Eagle Point? One of my clients received the latest version of Eagle Point, and the time to load files has become horrible. It has increased from 1 min to 15 min! All files are on the Linux server and the stations we did the initial tests with are PIII w/128MB RAM. The AutoCAD file loads quick, but once the Eagle Point files begin to load

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

Greetings all! A recent news item got me thinking that a problem stated therein could provide a teasing little exercise in R programming. http://www.bbc.co.uk/news/uk-england-cambridgeshire-17680326 Cambridge University hosts first European 'maths Olympiad' for girls The first European girls-only "mathematical Olympiad" competition is being hosted by Cambridge

Dear R list, What's the best way in R to fill a matrix who's entries depend on some function of the indices? I'm currently doing: Q <- matrix(0, k, k) for (A in 1:k) { for (B in 1:k) { Q[A,B] <- my.function(A,B) } } but I wonder if there is a more terse way.

I second this feature request (it's understandable that this and possibly other parts of the code was left behind / forgotten after the introduction of long vector). I think mean() avoids full copies, so in the meanwhile, you can work around this limitation using: countTRUE <- function(x, na.rm = FALSE) { nx <- length(x) if (nx < .Machine$integer.max) return(sum(x, na.rm =
