Hi All, I am looking into the feasability of using Samba/LDAP for domain control across several schools in my area, and would be interested to hear of anyone who has any experience/thoughts on how this could work. The schools share a community learning resource centre, and I am looking for ways for all users to be able to log in at their own schools, and also at the learning resource

Apologies for the novice question, but this is likely beyond my google searching range.. I am trying to create a table from the summaries of a file. The 2 column data table looks like; Harry 335/335 Harry 124/506 Harry 124/506 Dick 133 Tom 335/335 Tom 335/335 with 1000 unique values in col 1, 300 unique in col 2. The 'summary' doesn't seem

I've looked long and hard for this, but maybe I am missing something... There is a nice module that displays histograms reflected in the y axis, i.e. http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=136 but is it possible to reflect in the x-axis, so to have two datasets, one pointing up and one down rather than left and right? I haven't been able to find a way to plot this

I am receiving this error running a command on a multi-row data-frame. The data is strings of text (each with new line separator, no spaces, no numerical characters). Error in FUN(X[[1L]], ...) : STRING_ELT() can only be applied to a 'character vector', not a 'integer' I can run single text string into the same command, and so the issue seems to be how the package deals with the

This may be a simple problem, but I am looking to select a subset of rows from a dataframe that will have the same parameters as all the rows in another dataframe. e.g. I have a 500 row dataframe with 20 columns. I want to select a subset of rows from a larger dataframe that match the distribution of values for one or more of the columns within the 500 row dataframe (i.e. within same range, but

Hi guys I've just had a thought about something we do with our search on ReportBuyer.com: we cater for both American and British English in our searches and we have had plans for a while now to implement something that allows users to find 'colour' and 'color', 'tap' and 'faucet' by doing some clever programming. Looking at the Xapian docs, though, it appears

Hi folks, how does this look? http://wiki.winehq.org/PlatinumRegressionHunt I hope to publicise this once wine-1.0.0-rc1 is released. Let me know if the instructions are hard to follow. Thanks, Dan

Let's say that I have a bunch of matrices. They look like this (pardon using fruit for examples, my actual data tables are far too enormous): Matrix1 Apples Oranges Pears A 5 6 7 B 5 3 4 C 8 9 10 D 11 13 14 E 15 3 8 F 1 4 5

This is a very simple question, so I apologize I couldn't find it online: I want to shorten the string 'apples.pears' to 'apples'. string='apples.pears' string1=substr(string,0,x) For x above, I would like to have a command like charAt(string,"."), i.e. the position of the period in the word, but I can't seem to find a charAt command in R. Thank you.

Hi all, I'm trying to find something like the "==" operator that will work on vectors or something equivalent to SQL's "IN" function. For e.g., if I have: x <- c(1,2,3,4,5) y <- c("apples", "oranges", "grapes", "bananas", "pears") z <- data.frame (x,y) w <- c(2,4,5) I want R to return the values

Hi all, I have a very simple problem that I cannot seem to find the answer to. Consider the following toy dataset: x <- read.table(textConnection("V1 apples bananas cherries indv.1 7 8 4 3 indv.2 7 7 4 9"), header = TRUE) How would I change the column name of ONLY the first column, not the others? Surely I should not have to re-specify the names of ALL the columns -- e.g.,

[Apologies if this gets posted twice] Hi, I can't seem to get flush-behind to flush behind and I was wondering if anyone would be kind enough to lend some brain cells to help me see what I'm missing. I'm using glusterfs 2.0.1 on Debian/x86. I've got a "cluster/ replicate" volume replicated between two servers that are connected (over a VPN) over a slooooow

Hi, I am considering using R to integrate with a Java application. However, before deciding upon R I need to understand if R is capable of dealing with multiple requests simulataneously. Is a single instance of R capable of dealing with multiple simulataneous requests or does a new instance of R have to be started for each request? I have read Luke Tierney's 2001 notes on threading at

df=data.frame(country=c("A","A","A","B","B","B"), food=rep(c("Apples","Pears","Bananas"),2), X2000=c(4,5,6,7,6,8), X2001=c(4,5,6,7,6,8), X2002=c(4,5,6,7,6,8), X2003=c(4,5,6,7,6,8)); I have data in the above form trying to get a plot of each fruit over time year conditioned on country and

what does this mean in R-1.8.1 release notes? o median() no longer `works' for odd-length factor variables.

This is what I refer to as "ab uno disce omnes"-thinking: -- from one example all is revealed -- but this is the antithesis of statistical thinking. Here is an example function, others can probably do better. On a vector of length 300 it takes .018 seconds on my aging G5 ppc mac: pears <- function(x){ n <- length(x) A <- combos(n,2) rbind(x[A[1,]],x[A[2,]]) } This is

Hi, I am interested in integrating R with a Java front end. Before deciding to use R I am concerned about multi-threading. I have been investigating R's capability of dealing with multiple requests simultaneously (multi-threading) and have looked at Luke Tierney's 2001 notes for ideas for future releases of R at http://www.stat.uiowa.edu/~luke/R/thrgui/thrgui.pdf Is a single instance

Hi. I uses rpart to build a regression tree. Y is continuous. Now, I try to predict on a new set of data. In the new set of data, one of my x (call Incoterm, a factor) has a new level. I wonder why the error below appears as the guide says "For factor predictors, if an observation contains a level not used to grow the tree, it is left at the deepest possible node and
