Subscripting specified variables in a function
I'm trying to create a function which will allow me to subset a data set
based on values of various specified variables. I also want to then
apply some other function(s) (e.g., summary).
This is what I've tried so far....
> test.fx <- function(dta, expvar, expval) {
+ newdta <- subset(dta, eval(expvar)>expval)
+ summary(newdta$eval(expvar))
+ }

"Program" files
Is there any such thing as a program file in R? That is, is it possible to
compile and save code for performing data management and analytic tasks for
a given project into a single/multiple file(s) (i.e., like a script file
(S-Plus), a do file (STATA), or a *.sas file (SAS))?
Any words of wisdom or a point in the direction of some documentation would
be helpful. If it is not possible to work

Variable Descriptors
Is there a way to associate text descriptions with variables in a
data.frame?
For example...
Let's say that in my data.frame I have a variable named var1. var1
represents the responses to the question "When was the last time you saw
your physician?" When I tabulate the variable var1 I'd like the output to
be a bit more descriptive and contain the more descriptive

Detailed contingency tables
Is there any existing function for creating contingency tables that will
display counts, row, column, and cell percentages in the same
tables....anything similar to crosstabs in S?

Complex Surveys...Specifying Design
I need some guidance from someone who is familiar/has some experience with
the survey package.
The data that I am using is from the Medical Expenditure Panel Survey
(www.meps.ahrq.gov <http://www.meps.ahrq.gov/> ). The STRATA and PSU
variables are varstr01 and varpsu01 respectively. When I try to specify
them with the svydesign function I get an error message. An excerpt of my

Simulation help
I'm trying to simulate trend data over a five year period. I want
different trend profiles...the simplest being a linear trend. I've been
using the following code:
patBdta1 <- NULL
for(i in 1:100)
patBdta1 <- rbind(patBdta1,c(yr1= mean(rbinom(50,1,.50)),
yr2 =mean(rbinom(50,1,.51)),
yr3 =mean(rbinom(50,1,.52)),

R as shell script
Hi,
I am considering if I should invest in learning R. Based on the
language definition and introductory documents, it seems nice. But now
I am faced with a problem: I want to be able to run R programs easily
from the unix shell, and write scripts that can automatically select R
as the interpreter:
#!/usr/bin/R
cat("Hello world.\n")
This of course doesn't work, because /usr/bin/R

Sorting
What is the best way to sort a dataframe?
For example, how would I go about sorting a dataframe (with variables V1-V5)
by ascending V1, V2 and descending V3 while retaining V4 and V5.
Also, is there a relatively easy way by which to re-order my columns?
Thank you for your time.

Stepwise procedures
Is there a function in R which performs stepwise estimation in ways similar
to SAS/STATA (i.e., allows the analyst to specify the significance levels
for removal/addition of terms).
I've been asked to evaluate two final models: one resulting from a
backwards selection in R (stepAIC) and one resulting from a backwards
selection using PROC LOGISTIC in SAS. The final terms are slightly

Making R script to run in a console
Hi,
is possible to make a R script to run under a console without open the R
environment?
Something like this example.R
#!/usr/bin/R
function(name="Put here your name") {
print(name)
}
In a console I make
./example.R name="Ronaldo Reis J?nior"
then program print my name.
It is possible?
Thanks

weighted mean
How do I go about generating a WEIGHTED mean (and standard error) of a
variable (e.g., expenditures) for each level of a categorical variable
(e.g., geographic region)? I'm looking for something comparable to PROC
MEANS in SAS with both a class and weight statement.
Thanks.

Sipura g729 call quality to PSTN
If this has been covered before - I appologize.
We use some Sipura SPA-2000's with the g711 codec and all seems fine
(except for the occasional failure to register errors in my asterisk
logs - but I will save that for another post).
g711 call quality is on par with our Cisco 7960's. However, when
using the g729 codec, the call quality on the Sipura device goes
downhill on the PSTN side

Inefficiency of SAS Programming
If anyone wants to see a prime example of how inefficient it is to
program in SAS, take a look at the SAS programs provided by the US
Agency for Healthcare Research and Quality for risk adjusting and
reporting for hospital outcomes at
http://www.qualityindicators.ahrq.gov/software.htm . The PSSASP3.SAS
program is a prime example. Look at how you do a vector product in the
SAS macro

Forward stepwise procedure w/ stepAIC
I'm attempting to select a model using stepAIC. I want to use a forward
selection procedure. I have specified a "scope" option, but must not be
understanding how this works. My results indicate that the procedure begins

what I expected. Could someone please point out what I'm not

Dynamic visualisation of R data using Adobe FLEX
Hi useRs,
I had posted about Adobe FLEX talking to R for rich visualisation.
Reply from Jeffery Horner contained links to the
revolution-computing.com webpage which had information pertaining to
the Bay Users R group Meetup on Web Dashboards with R.
I have a very specific project that I need to implement.
I wish to use the graphics capabilities provided by Adobe FLEX to
visualise outputs from R.

how to pass user input to a function?
Hi everyone,
I'm building a website (http://yourpsyche.org) using Jeffrey Horner's
awesome Rapache module. I want to take user input, and pass it to an R
script. At first I was simply using if else statements, but after a
while I had so many nested if else's in my code that my head was
spinning. So then I started using cat() and source() to write
temporary files and read them back in
