Binning or grouping data
Newbie here. Many apologies in advance for using the incorrect lingo. I'm
new to statistics and VERY new to R.
I'm attempting to "group" or "bin" data together in order to analyze them as
a combined group rather than as discrete set. I'll provide a simple example
of the data for illustrative purposes.

Please help with legend command
Hi R-ers:
I'm drawing a plot and have used different line types (lty) for
different race/ethnicity groups. I want a legend that explains what line
types correspond to the different race/ethnicity groups. I used the
following code:
legend( 1992 , 42 , c("Hispanic" , "non-Hispanic white (NHW)" ,
"non-Hispanic black" , "AI/AN" , "Asian" ) ,

dotchart {graphics} 2.11.1 vs. 2.12.1
I have a factor vector of subject races (Asian, Black, Hispanic, White; n=30) that I want to plot with a Cleveland dotplot or dotchart.
I tried the following in R2.12.1 :
> dotchart(table(school$Race))
Error in plot.xy(xy.coords(x, y), type = type, ...) : invalid plot type
Using the same data set in R2.11.1 the operation succeeded (I tried several variations to be sure):

recode() function results in logical output, not factor output
Dear R Users:
I have race-ethnicity groups identified in the factor variable Ethnic_G.
I need to collapse Ethnic_G into a new variable with only two factors, 1 (White, non-Hispanic) and 2 (Minority).
As seen in the code and output below, the recoded race-ethnicity variable is put into logical format, not factor format.
I've used library(car) and the package was updated.

Successive Graphs
Hello! I have written an R script on a Windows platform where I
calculate eight result matrices I plot using matplot. I would like to
display the resulting plots successively, rather than simultaneously,
and I was wondering if anyone could point me in the right direction as
to how to do this. The graphs pop up in this manner by default when I
run my script in S-PLUS, with tabs separating them so I

manipulating multiply imputed data sets
Hi folks,
I have five imputed data sets and would like to apply the same
recoding routines to each. I could do this sort of thing pretty
easily in Stata using MIM, but I've decided to go cold turkey on other
stats packages as a incentive for learning more about R. Most of the
recoding is for nominal variables, like race, religion, urbanicity,
and the like. So, for example, to recode race

Non-Parametric Adventures in R
I just started using R and I'm having all sorts of "fun" trying different
things.
I'm going to document the different things I'm doing here as a kind of case
study. I'm hoping that I'll get help from the community so that I can use R
properly.
Anyways, in this study, I have demographic data, drug usage data, and side
effect data. All of this is loaded into a csv

tree problem
I am trying to use tree to partition a data set. The data set has 3924
observations. Partitioning seems to work for small subsets of the data,
but when I use the entire data set, no partitioning occurs. The
variables are:
RESP respondent to a survey (0 = not a respondent, 1 =
respondent)
AGE_P Age (continuous)
ORIGIN_I Hispanic Ethnicity (1 = Hispanic, 2 = non-Hispanic)

Tabulating using arbitrary numbers of factors
Dear R-help,
First of all, thank you VERY much for any help you have time to offer. I
greatly appreciate it.
I would like to write a function that, given an arbitrary number of factors
from a data frame, tabulates the number of occurrences of each unique
combination of the factors. Cleary, this works:

different output with fast-math flag
Why the output is different for this below program when compiled using
clang with fast-math optimization
#include<stdio.h>
int main() {
double d = 1.0;
double max = 1.79769e+308;
d /= max;
printf("d:%e:\n", d);
d *= max;
printf("d:%e:\n", d);
return 0;
}
prints 0 with fast math but 1 without fast math.

OT: Recommendation for a good Internationalized terminal software
Hi all,
We've got server-based application that runs on CentOS. Until now,
most of our customer's end-users have accessed the application using
either PuTTY or Teraterm. I was asked yesterday to try and find
internationalized add ons or alternatives for our new Asian customers
(Japan, Korea and China atm).
I figured if anyone would be able to recommend terminal emulation
