Dear R-experts I would like to read all files from a directory, the files have names "myname0001.txt" etc. I paste the directory plus file names and use "read.delim()". My problem is that some file names are missing, so I get an error and my program stops. Is there a way to check for a null pointer analogous to C, so that I can simply skip non-existent filenames? Please do

Hi, I have a problem executing "library(ROracle)" in R: OS/Software: Redhat 8.0, all available patches applied Oracle 9i v9.2.0.1.0 R v1.7.0 ROracle v0.5-0 DBI v0.1-5 The compilation and installation of ROracle went fine. However when I try to load ROracle I get the following: >> library(ROracle) >Error in dyn.load(x, as.logical(local), as.logical(now)) : > unable

Dear R users, I have a problem computing time differences using R. I have a date that are given using the following format: 20080620.00, where the 4 first digits represent the year, the next 2 ones the month and the last 2 ones the day. I would need to compute time differences between two vectors of this given format. I tried around trying to change this format into any type of time serie

I'm on R 2.1.0. In the "source" function there is a bug preventing the proper use of the chdir option (which simply doesn't work). The problem is that in the function the following line occurs: file <- file(file, "r", encoding = encoding) This overwrites the variable "file" and later causes the check if (chdir && is.character(file)

Dear all Just for fun, I have just downloaded the paper mentioned below and checked it with R-1.6.1. Everything is ok with exception of Table 2b, where I get always 1 instead of 0.5: > pbinom(1e15,2e15,0.5) [1] 1 Which value should be correct?

hi all, i would like insert a fucntion call at the end of each basic bloc the fucntion i have defined and declared at the begining of the module ie i have written a pass derived from a module pass virtual bool runOnModule(Module & M){ // i declared the fucntion and defined it for (Module::iterator a = M.begin(), b = M.end(); a != b; for (Function::iterator i = a->begin(), e =

You can then link with an object file that defines it. This is

I intend to port an R project from Linux to Windows. It involves C code that is loaded via dyn.load(). I could manage to produce a 'dll' File using cygwin which seems to be o.k. Now, using dyn.load("pcr.dll") i get: Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "c:/cygwin/home/pingu/rt-pcr/pcr.dll": LoadLibrary

Hi Nabila, > i would like insert a fucntion call at the end of each basic bloc you can't, because only terminators are allowed at the end of a basic block.

Dear All, I wonderif there is a simple way to draw a regression line in the xyplot: more specifically, let: age <- c(20:30, 31:40 ) age.cut <- cut(age, breaks = 2 ) y<- rnorm(20) x <- rnorm(20,4,1) xyplot(y ~ x| age.cut, xlab="x", ylab="y") How to draw (in the plot given by xyplot) the two regression lines (y ~ x) corresponding to the two category

My problem is as follows: i is a list of integers of variable length. Now I want to compute a new vector/array that contains 1's at the positions indicated in i. For example: c(2, 4) -> c(0, 1, 0, 1) Using something like i = i - c(0, i[2:length(i) - 1]); sapply(i, function(x) c(rep(0, x - 1), 1))); faces me with the problem of concatenating the result, which I could somehow not find a

Dear all, I have the following problem with the uniroot function. I want to find roots for the fucntion "Fp2" which is defined as below. Fz <- function(z){0.8*pnorm(z)+p1*pnorm(z-u1)+(0.2-p1)*pnorm(z-u2)} Fp <- function(t){(1-Fz(abs(qnorm(1-(t/2)))))+(Fz(-abs(qnorm(1-(t/2)))))} Fp2 <- function(t) {Fp(t)-0.8*t/alpha} th <- uniroot(Fp2, lower =0, upper =1,

Hi there, I want to generate a large amount of functions, say f=function(x,t) exp(-t[1]-t[2]*g_1(x)-t[3]*g_2(1+x)) where g_1(x) and g_2(x) are from a long list of moments, such as x, x^2, log(x), log(1+x) .. and so on. Any suggestions on how to do this efficiently? thanks a lot. x.w
