Basic Question on Keys/Values
As a java programmer, I'm having issue conceptualizing the following use case: Given an value, passed into a function, how do I pull out the lookup? Ie. A list of keys (key1, key2, key3) A list of values (val1,val2,val3) I want to write a function (or is there something built in?) such that Callit <- (thekey) { (magic happens here) Return value } Any ideas? Thanks a bunch!

Width of text displayed in R
All, I think this is pretty basic but I couldn't find the answer in any source. I have just built my own R for Linux (amd 64). It runs well, but R thinks that it only has 80 characters or so of screen width. I log on with Putty to the box and can stretch it as large as I want. Is there a simple way to tell R to use more screen width when displaying? From whatami: OS RELEASE :

Java to R interface
I am developing an application that uses Eclipse framework on Windows. I have to call R from Java. I downloaded rJava package and installed it. I set the classpath in the Run Dialog in Eclipse to the directory where the JRI.jar is. I set the Path environmental variable to the directory where R.dll and jri.dll are. Yet when I run the rtest example (in jri/examples directory), I get the

Displaying Grahics to the X Window when calling R from command line
Hi, I am running an R script from the command line by calling: > R --vanilla < test.R My terminal is part of the Xwin (Xterm) and there is a plot(1:10) command in the test.R script. This will not produce a grahic though. When I start R by calling R then plotting from the R command in the same xterm, I do get a graphic display. How do I create a xwin plot by calling R from the command

"open-ended" plot limits?
Hi Folks, Maybe I've missed it already being available somehow, but if the following isn't available I'd like to suggest it. If you're happy to let plot() choose its own limits, then of course plot(x,y) will do it. If you know what limits you want, then plot(x,y,xlim=c(x0,x1),ylim(y0,y1) will do it. But sometimes one would like to a) make sure that (e.g.) the y-axis has a

? extended rep()
Hi Folks, I'm wondering if there's a compact way to achieve the following. The "dream" is that, by analogy with rep(c(0,1),times=c(3,4)) # [1] 0 0 0 1 1 1 1 one could write rep(c(0,1),times=c(3,4,5,6)) which would produce # [1] 0 0 0 1 1 1 1 0 0 0 0 0 1 1 1 1 1 1 in effect "recycling" x through 'times'. The objective is to produce a vector of

A primitive OO in R -- where next?
Greetings All, Out of curiosity, I've just done a very primitive experiment: Obj <- list(Fun=sum, Dat=c(1,2,3,4)) Obj$Fun(Obj$Dat) # [1] 10 That sort of thing (much more sophisticated) must be documented mind-blowingly somewhere. Where? Where I stand right now: The above (and its immediately obvious generalisations, like Obj$Fun<-cos) is all I know about it so far. Ted.

'par mfrow' and not filling horizontally
Greetings, Folks. I'd appreciate being shown the way out of this one! I've been round the documentation in ever-drecreasing circles, and along other paths, without stumbling on the answer. The background to the question can be exemplified by the example (no graphics window open to start with): set.seed(54321) X0 <- rnorm(50) ; Y0 <- rnorm(50)

Output of binary representation
I am interested in studying the binary representation of numerics (doubles) in R, so am looking for possibilities of output of the internal binary representations. sprintf() with format "a" or "A" is halfway there: sprintf("%A",pi) # [1] "0X1.921FB54442D18P+1" but it is in hex. The following illustrate the sort of thing I want: 1.1001 0010 0001 1111

Understanding R Hist() Results...
Think I'm missing something to understand what is going on with hist(...) http://n2.nabble.com/What-is-going-on-with-Histogram-Plots-td3022645.html For my example I count 7 unique years, however, on the histogram there only 6. It looks like the bin to the left of the tic mark on the x-axis represents the number of entries for that year, i.e. Frequency. I guess it looks like the bin for

[follow-up] "Longitudinal" with binary covariates and outcome
Hi again! Following up my previous posting below (to which no response as yet), I have located a report which situates this type of question in a longitudinal modelling context. http://www4.stat.ncsu.edu/~dzhang2/paper/glm.ps Generalized Linear Models with Longitudinal Covariates Daowen Zhang & Xihong Lin (This work seems to originally date from around 1999). They consider an outcome Y,

Deb-4.0 Etch and sources.list for R
Hi Folks, I'm running Debian-4.0 Etch, installed last September from a DVD, and regularly updated as things arise. I have R version 2.4.0 Patched (2006-11-25 r39997) installed (initially at the time of first installation of Debian, as provided by Debian), along with a variety of packages. I'd like to be able to connect to the CRAN repositories for Debian R, for updates etc. When I visit

R vs SPSS contrasts
Hi Folks, I'm comparing some output from R with output from SPSS. The coefficients of the independent variables (which are all factors, each at 2 levels) are identical. However, R's Intercept (using default contr.treatment) differs from SPSS's 'constant'. It seems that the contrasts were set in SPSS using /CONTRAST (varname)=Simple(1) I can get R's Intercept to match

Unspecified [upper] xlim/ylim?
Greetings! I would like to be able to specify a fixed (say) lower limit for plotting, while leaving the upper limit "floating, when plotting. The context is that the maximum in the data to be plotted is unpredictable, being the consequence of a simulation, whereas I know that it cannot be less than (say) 0; and I want to fix the lower limit at 0 in any plot, leaving the upper limit to be

Re flect Back to Back Histograms in x-axis?
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

Organising tick-marks in plot()
Hi Folks, I'm advising someone who's a beginner with R, and therefore wants the simplest answer possible. The issue is to produce a plot using plot(x,y,...) where, on the X-axis, the tick-marks should be on the lines of: -- Range of X-axis: 0:1000 -- tick-marks labelled "0","200",...,"800","1000" -- unlabelled tick-marks every 50 from 0 to

Adding info from summary(lm(...)) to plot
Hi Folks, Say I have 2 continuous variables X,Y. I can of course plot (X,Y) with plot(X,Y,pch="+",col="blue") say, and add the regression line from lm(Y~X) by extracting the coefficients 'a' of Intercept and 'b' of X from Y.lm <- lm(Y~X). Now, however, I want to have not only a general explanatory title such as main="Plot of Y against X"
