set linetype with plotCI
Dear R-list,
I'm iterating several calls to plotCI [gplots], like so:
plotCI(
x = xvals.f[sorted],
y = yvals.f[sorted],
xlim = c(xmin, xmax), ylim = c(ymin, ymax),
pch = plot_symbols[graph_idx], type = "b",
lty = plot_linetypes[1],
col = plot_colors[graph_idx],
barcol = plot_colors[graph_idx], uiw = NA,
xlab = "", ylab = "",

density ellipses?
Hello,
has anybody written a function to plot density ellipses (95%, 99% or
anything) in a scatterplot? I found nothing in any package, nor in the list
archives.
There does seem to be a contributed package "ellipse" for S-Plus (on
S-Archive), but it does a lot more than what I would need. Still, if anybody
ported it to R, I'd be grateful for a link. I'm a bit afraid to try the

Why can't I figure this out? :S
Hi, so I don't speak computer and I have no idea what this code is telling
the program to do, but I apparently need to be able to find and isolate
influencial observations. Problem, I have no idea what the error means and
where it may be from in the code.
error I get is below the code

Creating a new table from a set of constraints
Hi Everyone,
Here's a silly newbie question. How do I remove unwanted rows from an
R table? Say that I read my data as:
X <- read.table("mydata.txt")
and say that there are columns for age and gender. Call these X[5] and
X[10], respectively.
Here, X[5] is a column of positive integers and X[10] is binary valued
i.e., zero (for male) and one (for female)
Now, say that I

Basic Dummy Variable Creation
Hi There,
While looking through the mailing list archive, I did not come across a
simple minded example regarding the creation of dummy variables. The
Gauss language provides the command "y = dummydn(x,v,p)" for creating
dummy variables.
Here:
x = Nx1 vector of data to be broken up into dummy variables.
v = Kx1 vector specifying the K-1 breakpoints
p = positive integer in the range

save at relative directory
Dear all,
I have a variable called thres and before I run a script I set it to a value
like
thres<- -10
at the end of the execution I am issuing a save(variablename,file='Results')
which will end up with a file saved at the current directory with the name Results
I would like though to use thres value and do the followingg

Sample size calculations for one sided binomial exact test
I'm trying to compute sample size requirements for a binomial exact test.
we want to show that the proportion is at least 90% assuming that it is
95%, with 80% power so any asymptotic approximations are out of the
questions. I was planning on using binom.test to perform the simple test
against a prespecified value, but cannot find any functions for computing
sample size. do any exist?

[LLVMdev] Loop transformations using LLVM
Hi
I am trying to write up a transformation for the following code where
instead of incrementing the loop variable by 1, I increment it by 2 ie.
for (i=0; i < THRES; *i++*) {
//do something
}
gets transformed to
for (i=0; i < THRES; *i+=2*) {
//do something
}
I am thinking of transforming the llvm bit-code in the following way.

Conditional error bars
How can I condition any error bar function that use the arrows() function,
such as 'CI.plot' (see example below) or 'error.bars', to draw only upper
error bar (upper CI) if the bar value (mean) is positive and the lower
error bar (lower CI) if bar value is negative?
CI.plot <- function(mean, se,length, ylim=c(-5, max(CI.H)), ...) {
CI.H <- mean+se
CI.L <- mean-se

A plotting question - how to get error bars?
Dear R list,
Can anyone help with a plotting question? I'm trying to display some data
on a plot and I've almost got the format I need (see code below), but 2
things I can't get:
1. How to get "Jan","Feb","Mar" on the x=axis instead of 1:3?
2. How to get "T"s on the end of my error bars like you have in standard
scientific plots?

How to avoid the NaN errors in dnbinom?
Hi, The code below is giving me this error message:
Error in while (err > eps) { : missing value where TRUE/FALSE needed
In addition: Warning messages:

2: In dnbinom(x, size, prob, log) : NaNs produced
I know from the help files that for dnbinom "Invalid size or prob will

Replacing elements of a list over a certain threshold
Dear List,
I have a list of length ~1000 filled with numerics. I need to replace
the elements of this list that are above a certain numerical threshold
with the value of the threshold.
e.g
example=list(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1)

From Java to R OOP
Hi, I'm new to OOP in R so please forgive the naiveness of some of the questions. Here are a couple of them. It would be great if you can contrast to OOP in Java.
1. R's S4 appears to centered around a dispatch mechanism which in my understanding is just a way to implement polymorphism. Now, here's the snag, I thought polymorphism was an aspect of OOP not by itself the definition of

help with bivariate density plot question
Dear R users:
I have a dataset with two variables (>20000 observations, two samples from same subject) and I used "kernSur" from library(Genkern) to
get a estimated bivariate density and corresponding plots as follows:
new.data.normal<-data.normal[!is.na(data.normal[,2]),]
x<-new.data.normal[,2]
y<-new.data.normal[,3]

bar plot with non-zero starting level
Hi,
I want to plot grouped bars to compare 95% confidence interval estimates
from two models. Each bar represents a 95% confidence interval estimate
of a coefficient from one of the two models. Each group represents
confidence interval estimates of the same coefficient from the two models.
I think such a bar plot will nicely present whether 95% confidence

resolution of windows metafiles
I am having trouble getting smooth-appearing curves in figures produced as
windows metafiles using R (R-1.1.1 on Windows 98). When I import them into
a word processor (either MS Word 97, or WordPerfect 9.0), the figures
appear only slightly bumpy on screen, but when printed, there is a clear
jaggedness reminiscent of aliasing. Is there a fix for this (if the answer
is "upgrade to 1.2",

ggplot2 geom_rect(): What am I missing here
Hi R fans,
As a newbie following the five-hour rule (after hitting my head against
the wall for five hours, post to this list), I am appealing for some
help understanding geom_rect() in ggplot2.
What I want to do is very simple. I want to generate a plot of
rectangles. Each one represents a business cycle. The x-values will be
pairs representing the start and end of each cycle. The y-values

lineplot.CI problem
Hi List,
I have a problem plotting data using the lineplot.CI command in the sciplot package.
I want to plot the data of 2 experimental cases using different lines (traces). Time is on the X-axis. The tricky thing is that the data collection in the second case started later than for the first case. This is to say: the first n data points for the second case are missing.
So far so good. However,

Help in Overlaying of 2 Plots on the same Device.
I'm trying to overlay a density plot on a previously plotted histogram. However, i need to use the same axis as of the 1st(histogram) plot to plot the second. My second plot is creating its own axis and causing my plot to extend the entire histogram instead of getting a subplot on a portion of the histogram. I tried 'fig' and 'new' parameters with no luck.
Thanks in advance.

[LLVMdev] Loop transformations using LLVM
Malveeka,
You can use the LoopInfo analysis to find the induction variable.
