I would like to make readline's command history in R-0.63.1 substantially larger than it is by default (seems like around only 50 commands). How do I change the size? Thanks! -- Russell Senior seniorr at teleport.com...

I am interested in making a random sample from a uniform distribution of points over the surface of the earth, using the WGS84 ellipsoid as a model for the earth. I know how to do this for a sphere, but...

I am a relative neophyte to R and am faced with a problem of constructing a reduced data set from a diversity of separate sources. What operations are available in R for combining and matching attributes from separate data.frames...

I know how to pull a copy of the current R release sources using rsync. How do I do the same thing for the current add-on packages? Thanks. -- Russell Senior ``The two chiefs turned to each other. seniorr at...

I've got a set of data that are weighted by a largish integer (ranging from about 50K to 1.5 million). I'd like to plot CDF's for this data taking into account the weighting. What do you...

Compiled on Debian Linux 2.0: Three of the contrib packages (event, repeated and rmutil) contain a src/inthaz.c file with an include file ../../../include/Mathlib.h, where (at least in R 0.63) just a plain Mathlib.h...

Suppose I have a set of binned data, counts exceeding a series of arbitrary thresholds, a total N, a minimum and maximum, those sorts of things. Is there a "standard" method for estimating arbitrary quantiles from this? My initial thought...

Given a set of data: > names(data) [1] "city" "house" "visit" "value" I am looking for a way to compute the variance components of the nested model (ie, visit 1 at house 2 at city 3 isn't related to...

I want to write a function to take an argument as the response variable of a linear model, e.g. to do anova's across a list of variables, something like the following (except, of course, this doesn't work...

I am getting ready to load a bunch of data into R. The data is all numeric, but some of the numbers are integer codes representing non-numeric semantics. What is the best way to "fix" the data frames so...

I am generating some graphs (on GNU/Linux using R 1.5.x) for a PowerPoint presentation my boss is giving next week. He just tried cut/pasted a plot off of a PDF file I had created, but he...

I"ve got a data frame with a selection of columns I want to compute a rank-order correlation matrix from without disturbing the original data frame. foo[,c("a","b","d","f","g")] What I wanted to do, intuitively...

I am writing a little abstraction for a series of tests. For example, I am running an anova and kruskal.test on a one-factor model. That isn't a particular problem, I have an interface like: my.function <- function...

I am writing some R code that generates some figures. I am primarily developing on GNU/Linux, but will ultimately run the code on Windows in order to get WMF files I can integrate in an existing document. The win...
