Quick question: Which function do you use to calculate partial derivatives from a model equation? I've looked at deriv(), but think it gives derivatives, not partial derivatives. Of course my equation isn't this simple, but as an example, I'm looking for something that let's you control whether it's a partial or not, such as: somefunction(y~a+bx, with respect to x,

There are multiple marketing models in place to predict individual-level probabilities of whether or not someone would respond to a solicitation, whether or not they would become a customer, and if they did become a customer, how much money the company is likely to make. Each individual receives a score from each model, and the final goal is to rank all individuals based on a final score. As

Hi, I am plotting scatterplots of horsepower by torque, conditional on brand (I'm just making up the variables for this example), and the goal is to see both the scatterplot points as well as the smoothed line. When I do the following code, I get the same color for the points and line, and would like the colors to be different, such as black points and a red smoothed line. How do I do that?

This weekend I noticed that my R2WinBUGS connection was no longer working on my Windows computer at work AND my Ubuntu linux computer at home. As soon as WinBUGS opens, the message reads Index Out Of Range. I have un-installed and re-installed R on both computers and the problem remains the same. At first I thought it was the new version of R, but I was able to overcome the problem (on Windows

Hi, I'm not used to thinking along these lines, and wanted to ask your advice: Suppose you have a sample of around 100, consisting of patients according to doctors, in which patients and doctors are given a questionnaire with categorical responses. Each patient somehow has roughly 3 doctors, or 3 rows of data. The goal is to assess by category of each question or DV the agreement between

This seems pretty basic, but I can't get any data to work except for the documented examples. When the goal is to get to SpatialPixels, here is what I see... > x <- runif(10,1,10) > y <- runif(10,1,10) > z <- rnorm(10,0,1) > MyData <- as.data.frame(cbind(x,y,z)) > library(gstat) > coordinates(MyData) <- ~x + y > gridded(MyData) <- TRUE suggested

I'm new to spatial analysis and am exploring numerous packages, mostly enjoying sp, gstat, and spBayes. Is there a function that allows the user to dedup a data set with multiple values at the same coordinates and replace those duplicated values with the mean at those coordinates? I've written some cumbersome code that works, but would prefer an efficient R function if it exists.

Hi, Here is a step-by-step guide to exactly how I've installed R in Ubuntu: http://www.nabble.com/installing-R-on-Ubuntu-td10025949.html#a21894865 Regarding rjags, here is what happened: This webpage (http://yusung.blogspot.com/2009/01/install-jags-and-rjags-in-fedora.html) recommends logging into R as sudo R, and then typing: install.packages("rjags",

I'm interested in easing my way into learning VIM by first using the Cream text editor, liking the idea that it will work on both my Linux and Windows computers. I've installed Cream on my Linux machine, but can't figure out how to make Cream talk to R? Does anybody know? I'm using Ubuntu if it makes a difference. Thanks. -- View this message in context:

Hi all, I've managed to get JAGS working on my Ubuntu Hardy Linux with a 32-bit computer and AMD processors using R 2.8.1. JAGS is great. I've read that JAGS is the fastest, but that hasn't been my experience. At any rate, I have more experience with WinBUGS under Windows and would like a version of that working as well. It seems like I've read a lot on the subject and tried a

I'm trying to code more R-like and avoid loops. Here is an example I'm having a hard time getting away from loops with, and the real matrices are rather large, and the computation is too time-consuming. ### Dimensions N <- 2 M <- 3 P <- 4 ### Array and Matrices nu <- array(NA,dim=c(N,M,P)) Lambda <- matrix(1:12,P,M) F <- matrix(1:8,N,P) ### Loop to avoid for (i in 1:N)

There is certainly a trivial solution for my question, but I can't find the answer in the documentation. I need a platform independent method to obtain the file path of the current R script. My working group uses R on several machines with different operating systems including Mac OS X, Windows and Linux, and for obvious reasons the file hierarchies are very different. Therefore, it

Dear All, I came across a really strange behaviour when using winbind on solaris 8. Normally "nscd" should be turned off because it's causing problems in the username resolution etc. When I turn it off I can login e.g. using ssh as an AD users but when i start a command like "ls" it gets put in the background immediately? When "nscd" is turn on and login again I

Dear helpeRs, a colleague of mine would like to give R a try. He uses econometric models which typically involve a large number of variables, esp. time series. Having no experience with handling very large data sets myself I turn to you. 1. Could you please describe your experiences to cope with these situations? 2. What kind of difficulties will he have to face? Are there special

Dear HelpeRs, I'm very fond of Sweave and I use it as often as possible. It'a a pity I can't use it for larger projects or can I? For instance suppose I have three files file1.rnw, file2.rnw and file3.rnw with Sweave code. Working on file2.rnw I whould like to exclude file1.rnw and file3.rnw temporarily and joining all of them later. This amounts to a mechanism similar to using

Dear HelpeRs, I wonder if anyone knows of ways to read EViews file types. I did not find a function in the package 'foreign' and a search query submitted to http://search.r-project.org was not successful. Any hint is very much welcome.
