Matrices with randomly generated entries
I'm attempting to generate matrices where the entries are randomly generated
numbers of specified distribution.
The following code was an attempt to create a 3 by 3 matrix, where my
entries where randomly generated from a uniform (0,1) distribution.
x = matrix(0,ncol = 3, byrow = T)
for(i in 1:3) {
for(j in 1:3) { x[i,j]= runif(1,0,1) }
}
The problem I get with the above code however is

R in rearranging equations
Hi,
can anyone tell me if R can be used to rearrange very complicated equations
in terms of one of the variables?
I have:
dx/dt = a*b*m*y*(1-x)-r*x
and, having set:
dy/dx = 0,
need to rearrange in terms of x. The problem I have is that I don't know how
to rearrange equations when the variables are not yet defined (I get
messages warning me that x etc can't be found). I'm not sure

Today I ran some 3D demos, just for fun (from
http://www.vividimage.enta.net/electrome/) !!!
When the demo ends and gives me back a gnome desktop all my panels icons had
rearranged and ended up at the right hand corner in a tiny clump.
In windowed mode its fine just full screen.
Any ideas? Should I file a bug report or is this

rearranging data frame rows
Hi All,
I have two data frames. The first contains data about a number of individuals,
coded in the first column with a name, in an order I find convenient.
The second contains different data about the same indivduals, in a different
order. Both data frame have the individual names in the first column.
I need to reorder the second data frame so the rows are rearranged in the same
manner as

Rearranging Data
Hi everyone,
A few days back Jim helped with out, helping me find an automated way of
determining the mean and median of intervals between price changes.
However, a new set of data I have is no longer in the same format.
CDSmod is the file that was used with this code:
x <- read.csv('/cdsmod.csv', as.is=TRUE, check.names=FALSE)
x$Date <- as.Date(x$Date, "%m/%d/%Y")

Resolution changes sometimes rearranging desktop
Sometimes when I play games that use a resolution different from my normal X display, the windows on my workspace get shifted over toward the upper left. It's an issue that's been happening for a long while and I'm not sure if this is more of a general X issue or something specific to wine. As far back as I remember, it only happens with wine (0.x-0.9, 1.0, 1.1) and I've seen it in

heatmap.2() problems with re-ordering of rows and columns
I have a file of the following form
-11 -10 -9 -8

Rearranging subtrees and Eisen Cluster
I am attempting to replicate what Cluster 3.0 and Treeview (both by Mike
Eisen) to cluster both microarray genes and arrays does using R with
hclust. I basically utilized the plot.mat function in sma library with
some layout() and hclust().
1. Can I know if some has already written such a function or available
in some package.
2. If not, would appreciate if someone could take the time to test

Rearranging a data frame for multiple observations
Hi there,
I think I'm struggling with a fairly simple problem but can't seem to solve
it. I have multiple observations for one unique identifier. Ultimately I
want to end up with one line per identifier with multiple observations in
rows. I'm really stuck any help would be really appreciated.

packet rearranging questions
Hello again. If you recall, I am the guy working on enabling Audacity
to losslessly rearrange Ogg Vorbis files for my senior thesis. I have
more or less completed the required modifications to Audacity to support
this. You can read more about the work this entailed by reading my
journal:
