Bivariate Normal Distribution Plots
R-Help
I am attempting to create a series of bivariate normal distributions. So using the mvtnorm library I have created the following code ...
# Standard deviations and correlation
sig_x <- 1
sig_y <- 1
rho_xy <- 0.0
# Covariance between X and Y
sig_xy <- rho_xy * sig_x *sig_y
# Covariance matrix
Sigma_xy <- matrix(c(sig_x ^ 2, sig_xy, sig_xy, sig_y ^ 2), nrow = 2, ncol = 2)

ggplot2 = bar size
Hi,
i am newbie into ggplot and i thow that i have to learn a lot about this package.

Starcraft Patch
I've done some work getting the patches from
http://starcraft-wine.sourceforge.net/ working with CVS wine. Using the
patch I'm including, starcraft works perfectly on my machine, run as
root using DGA on a 640x480 XF86 layout.
In particular the changes to event.c enable the mouse and keyboard with
DGA. The changes to input.c make the mouse acceleration work the same
in all directions.

[LLVMdev] Structure Alignment
Hi,
I have a problem using structs, when calling a function written in C from
a LLVM function or calling a LLVM function from a C one.
I noticed that the LLVM align double with 4 bytes and our run time routines
use 8, in MS Windows.
If a use #pragma pack(4) in my C programs, the routines run fine, but
I must ensure that all external call should use the #pragma directive.
If I change the llvm

I had not applied the layout at run time, only during the emission of the .bc.
Now it's running ok when I allocate the structure point at LLVM side, but, when I allocate the structure pointer in the C

Diagonal population density
Dear all. I have to plot a the marginal population density for a heat map that represents the population density of a city. I have been able to plot the heat map in the lower left corner, the marginal density in x in the upper left corner and the marginal density in y in the lower left corner. What I need is to change this plot to include the marginal density in the diagonal direction of 135

sample consecutive integers efficiently
Hi all,
I have some rough code to sample consecutive integers with length
according to a vector of lengths
#sample space (representing positions)
pos<-c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20)
#sample lengths
lengths<-c(2,3,2)
From these two vectors I need a vector of sampled positions.
the sampling is without replacement, making things tough as the sampled
integers need

Missing ids in documentation
I notice some link that didn''t work in the documentation.
By closer inspection I found that some of the headlines missed
id-tags.
The following grep sequence find them.
grep ''<h3'' *.html | grep ''#'' | grep -v ''id=''
Here is the output

Ternaryplot as an inset graph
Hello
I am trying to add a ternary plot as a corner inset graph to a larger
main ternary plot. I have successfully used add.scatter in the past for
different kinds of plots but It doesn't seem to work for this particular
function. It overlays the old plot rather than plotting as an inset.
Here is a simple version of what I'm trying. Note that if I change the
inset plot to be an ordinary

R function for computing Simultaneous confidence intervals for multinomial proportions
Dear all,
Does someone know an R function implementing the method of Sison and
Glaz (1995) (see full ref below) for computing Simultaneous confidence
intervals for multinomial proportions?
As alternative method, I think to boostrap the mean of each proportion
and get in that way confidence interval of the mean.
I observed 21 times a response that could be one out of 8 categories

reverse lexicographic order
Hi all,
I have some email addresses that I would like to sort in reverse
lexicographic order so that addresses from the same domain will be
grouped together. How might that be done?

Single plot multiple levels in x?
Plotting with 2 x axis?
One axis inside another, for example salary within state,
1-50 | 50 ? 100 | 100+ | 1- 50 | 50 -100 | 100+ | ? repeated bins for salary
AL ! AR ?? more states
The values are all stored with a single data frame. I have tried different things with the axis function and done many

Fitting distribution in range
Hello.
I am trying to fit my data sample x with different distributions such that
the integral from min(x) to max(x) of the fitted distribution will be one.
Therefore I have wrote my own log-likelihood functions and then I am using
mle {stats4}. So, for example:
ll_gamma <- function(a,b) {
integrand <- function(y){dgamma(y, shape=a, rate=b)}

mca id numbers
Is it possible to make disappear the id numbers from scatter.dudi (mc

a <- as.factor(c(1, 2, 3, 2, 1))
b <- as.factor(c(3, 2, 3, 1, 1))
x <- as.factor(c(1, 2, 2, 1, 3))
y <- as.factor(c(2, 2, 3, 1, 1))
dat <- data.frame(a=a, b=b,x=x,y=y)
summary(dat)
dat
require(ade4)
dat.acm <- dudi.acm(dat, scann = FALSE, nf = 2)

Thank you very much !

plotting other axes for PCA
Hi R-community,
I am doing a PCA and I need plots for different combinations of axes (e.g.,
PC1 vs PC3, and PC2 vs PC3) with the arrows indicating the loadings of each
variables. What I need is exactly what I get using biplot (pca.object) but
for other axes.
I have plotted PC2 and 3 using the scores of the cases, but I don't get the
arrows proportional to the loadings of each variables on
