I have a matrix with 2 columns and n row. I need sort the matrix by the first
column but the second row must be sort in the same order that the first
column. Somebody know how I can sort this matrix.
Thanks very much

Hi all,
I'm interested in doing a multiple density plot on a number of columns in a
dataframe.
DF
lineA.1 lineA.2 lineB.1 lineB.2
r1 5.355354 6.665575 10.288498 11.74750
r2 3.643415 5.427600 11.407112 13.97065
r3 5.813674 6.438502 9.628871 11.57456
r4 5.241340 5.125049 10.456221
Where were you reading about that function?
simple.densityplot seems to be from a user-supplied package called UsingR.
Try
install.packages(UsingR)
library(UsingR)
and then try your simple.densityplot function call.
Best,
Erik Iverson

Howdy,
In SPSS, there are 2 ways to weight a least squares regression:
1. You can do it from the regression menu.
2. You can set a global weight switch from the data menu.
These two options have no, in my experience, been
i'm in the midst of using R for a PVA/matrix project. my math skills are
lousy and programming skills are worse. to deal with an error that i
couldn't solve, i changed a parameter that used a new part of a routine

else if (ES == ParDraw) {
require(MASS)
It works!!!
Thanks a lot Chuck!

Hi Folks,
I'd be grateful for suggestions about approaching the
following kind of data. I'm not sure what general class of
models it is best situated in (that's just my ignorance),
and in particular if anyone could point me to case studies
associated with an R approach that would be most useful.

Hello:
I'm trying to use levels function, but I don't know why it's returning NULL.
For example:
temp[1] 3 5 5 NA levels(temp)NULL
Also, I've tried:
list(temp)[[1]][1] 3 5 5 NA
levels(list(temp))NULL
Is there a specific requirement on the parameter?

It would appear that the SPSS procedure would then give exactly the same
point estimates of the parameters, and change the inference structure by
changing the ``denominator degrees of freedom'' from n-p to sum(w) - p.
This seems to me to make little sense ... But then, it ***is***
SPSS. :-)

Well, if that IS what SPSS
