...program which does a 'monte-carlo' type simulation. However, it is written in a way which seems a bit un-natural in R. Could someone help me make this a bit more R-ish please?

Hi all, Thanks to Dr Paul Murrell in New Zealand to remind me of security consideration. I am releasing version 0.2 with security fix. This version will allow you to add banned R function names in a list. R_PHP_Online is a PHP CGI web interface to run R programs online, with the capability to show graphics online. You can get current version of R_PHP_Online from http://steve-chen.net/R_PHP/

Is there a function in R to calculate the generalized determinant of a singular matrix? - similar to the ginv() used to compute the generalized inverse. I can't seem to find any R related posts at all.

Good evening, Spotted a very minor spelling mistake in the source for the grep help. And thanks to R-Core for all their work - it's a tribute to R-Core, that these sort of "problems" are rare indeed.

Good morning, I've searched high and low and I've tried many different ways of doing this, but I can't seem to get it to work. I'm looking for a way of vectorising a "running balance"; i.e. the value in the first row of the dataframe is zero, and following rows add to this running balance. This is easy to write in a loop, but I can't seem to get it working in

Hi, when mixing newline and backspace characters I get the following output (see below). In the second call, the backspace character is simply not applied. Is this normal behaviour? Thank you. > cat("abc\b") ab> cat("abc\b\n") abc > [[alternative HTML version deleted]]

Good afternoon, A strange one - library(rJava) works for root but not for user sean On 64-bit Ubuntu 9.10, using R as root (sudo -i), I can say library(rJava) and it works fine with no error message of any kind.

Good morning, I have currently 63 .csv files most of which have lines which look like 01/06/05,23445 Though some files have two numbers beside each date. There are missing values, and currently the longest file has 318 rows. (merge() is losing the head and doing runaway memory allocation - but thats another question - I'm still trying to pin that issue down and make a small repeatable

Good morning, I wonder could somebody help me bridge the gap? I want to try and simulate a "factory" type environment with an object moving between stages of production with errors and re-work. The intent of this is to demonstrate the effect of error rates and re-work at various stages in the 'factory' on the total volumes of work at each stage of the factory - in order to

Good afternoon, As a clarification does it make sense to remove the second 'not' in the 'See Also' documentation for file_test ?

Good morning, Is there a way to get table() to default to including NAs - as in... table(..., useNA='ifany') or table(..., useNA='always') or table(..., exclude=NULL) ? I can't see a way under table() or options() or searching the archives (probably using the wrong keyword?). > t1 <- c(1,2,3,3,3,2,NA,NA,NA,NA) > table(t1) t1 1 2 3 1 2 3 I keep forgetting to

Working on Windows I have had to deal with CSV files that, unfortunately, contain embedded Control-Zs, i.e. ASCII character 26 in decimal, and the readLines() function in R on Windows (2.15.2 and 3.0.0) appears to truncate at the control-Z. There is no problem at all on Ubuntu Linux with R 3.0.0. Am I mistaken or is this genuine? # Create a small file with embedded Control-Z h3 <-

Good morning, I'm trying to concisely generate a single integer from 0 to n inclusive, where n might be of the order of hundreds of millions. This will however be used many times during the general procedure, so it must be "reasonably efficient" in both memory and time... (at some later stage in the development I hope to go vectorized) The examples I've found through searching

Good morning! I've searched the docs etc... Am I doing something wrong or is this a bug? I'm doing a merge of two dataframes and getting extra rows in the resulting dataframe - the dataframes being merged might have NAs... count <- 10 nacount <- 3 a1 <- as.data.frame(as.Date("2005-06-01")+0:(count-1)) names(a1) <- "mdate" a1$value <- runif(count)
