Creating a Model Matrix - keeping NAs
I am wanting to create a model matrix and keep the NAs.
stratmat <- model.matrix(myformula,mydata)
Is there any way to do this? model.matrix doesn't have na.action as a
parameter. Elsewhere I have made use of na.keep <- function(x){x}.
Many thanks,
Rachel Cunliffe

Pulling columns out of a data.frame
Hi there
Probably a very simple solution to this problem.
I have a character vector eg c("name1","name2","name3") and I want to pull
out these columns from a data.frame, converting each of these columns into
factors also.
Many thanks
Rachel

Decimals in R/SQL
Hello,
When I am writing in sqldf or RSQLite I lose the decimals in my matrix.
The only way I can get decimals is by multiplying by 1.00000, etc. I
have tried manipulating the options, but it is only effective once I
multiply by 1.0000.
I appreciate any suggestions!
Thanks!
Example:
z <- sqldf ("select ST,
SUM(AGEP*PWGTP)*1.000000000/SUM(PWGTP)*1.00000000000000 as wgtage from

Centos doesn't load or work
I've tried Zorrin, Ubuntu and Centos.
Zorrin and Ubuntu work fine, but Centos doesn't load, or run.
I asked for advice, didn't get any and seem to have been added to all your Centos mailing lists.
Please remove me from your mailing lists.
Sincerely,

Stratified data summaries
Hi All,
I'm trying to automate a data summary using summary or describe from the
HMisc package. I want to stratify my data set by patient_type. I was
hoping to do something like:
Describe(myDataFrame ~ patient_type)
I can create data subsets and run the describe function one at a time,
but there's got to be a better way. Any suggestions?

creating a vector of sums
Hi,
I am trying to create a function for a goodness-of-fit test for the Pareto Distribution for some loss data that I have.
So far I have the following:
function(X=OTOL)
{
n <- length(X)-1 #calculated the number of values (extra as 0 included)
i <- 2:640 #values of i
j <- 1:639 #values of i-1
Y <- (n-j+1)*((X[i])-(X[j])) #First part of GoF model
Y
}
Where OTOL is the ordered loss

subset dataset using factor levels instead of factor names
Hi All,
I have a factor variable with 52 levels -with long, annoying names. I want to keep only rows with some variables. I can do this using this code:
test1 <- subset(nih2009,ic_name %in% c('NATIONAL EYE INSTITUTE','Veterans Affairs'))
dim(test1)
[1] 2396 38
But this doesn't work:
t1 <- subset(nih2009, ic_name %in% c(27,51))

Problem with tick marks in lines.survfit (package survival)
I have attempted to follow posting guidelines but I have failed to find out
what I am doing wrong here.
I am trying to use lines.survfit to plot a second curve onto a survival
curve produced by plot.survfit. In my case this is to be a progression free
survival curve superimposed upon an overall survival curve, but I will

Once I added this HABTM, one of my 'through' relationships, on a non-habtm model, seems to have broke?
I''m a rails newb and have been Googling about this, but I''m still stumped.
Not showing everything here, but basically it should be a pretty common
setup so I''m sure others know what I''m doing wrong.
- A meter can belong to many meter_groups
- A meter_group can have many meters.
- A user can ''subscribe'' to viewing a meter_group (Subscription)

viewing data in something similar to 'R Data Editor'
Hi,
I would like to view matrices I am working with in a clean, easy to read,
separate window.
A friend showed me how to do something like I want with edit(). I can view
the matrix in the 'R Data Editor':
For a sample matrix:
> mat=matrix(1:15,ncol=3)
> mat
[,1] [,2] [,3]
[1,] 1 6 11
[2,] 2 7 12
[3,] 3 8 13

undesired grid in ps/eps outputs generated by filled.contour or image
Hi!
Whenever I save a graphic in ps/eps format generated by filled.contour or
image, an undesired grid is added to it (not visible on the X11 screen). For
example:
postscript("volcano.eps")
filled.contour(volcano,col=gray(seq(0,1,,50)),levels=seq(min(volcano),max(volcano),,50))
dev.off()
Any ideia how to eliminate this grid?
Thanks,

Tick marks in lines.survfit
I posted several months about the problem with adding tick marks to curves
using lines.survfit.
This occurs when lines.survfit is used to add a curve to survival curves
plotted with plot.survfit. The help for this function implies that
mark.time=TRUE thus:
plot(pfsfit,conf.int=FALSE,xscale=365.25,yscale=100,xlab="Years",ylab="%
surviving",lty=2,mark=3)

Newb question about facade columns
Hello,
I am trying to deal with a database table that contains a date in the
form of the number of seconds since epoch. Data is inserted in this
format by an existing script that I can''t change, so a schema change
isn''t realistic.
I would like to allow humans to view and edit this data in the form of
an actual human-readable date. I figured a facade column would be the
