In short, the answer to your question is how factors are encoded as integers
in R. If you run something similar to this code (except that actually runs)
you'll note that as.numeric(f1) = 1.

How do i get substitute to work on the contents of o.

I have used do.call("substitute", ...) to work around the
fact that substitute does not evaluate its first argument:
R> z <- quote(func(arg))
R> do.call("substitute", list(z, list(func=quote(myFunction),
arg=as.name("myArgument"
myFunction(myArgument)

Hi:
Having just seen your follow-up question, here's how it could be done
in ggplot2 or lattice:
# ggplot2 version:
ggplot(w, aes(x = age, y = outcome)) + geom_line(aes(group = .id)) +
stat_summary(fun.y = 'mean', geom = 'line', color = 'blue', size = 2)
# lattice version:
xyplot(outcome ~ ag

Hi all, thanks very much for sharing your thoughts. and sorry for my describing
the problem not clearly, my fault.
My data is paired, that is 2 different diagnostic tests were performed on the
same individuals. Each individual will have a test results from each of the 2
tests. Then in the end,

Although I sent the mail to Piotr, the author of FSelector, it should be better

Hi Jean,
Thanks for the reply..
Using your suggestion, I end up in in the source code (Fortran 77 i
believe). At first look, it seems a bit more tedious to implement than I
expected.

Hi,
Premises: I have a database which contain the list of events and their time
stamps (This is a Unix time stamps)
What I want to do : I want know how much is the maximum occurrence of this
in any a time period of 7 days or does a event occur es more than "N" (say
5) times in a period of 7 days
Thanks!
That's exactly it.
get gets it ;-)

The get() function should get you where you need.

Hi,
I am using the package ncdf to create netCDF files and I want to mimic the the
header of an exiting netCDF file created outside of R. Below is what the
existing header looks like (part of it that is different):
netcdf ccd1984_05_08 {
dimensions:
lat = 1974 ;
lon = 1894 ;

Yea, I don't know why there is no mean summary line showing up. I requested
it in the interaction.plot statement (fun = mean), and I don't get any
errors. Any ideas?

Hi all,
This seems like a basic problem, but no amount of playing with the code has
solved it. I have a time-series data set like that shown below (only longer)
and am seeking to plot the data with filled, circular points and error bars.
I would like the error bars to be behind the points otherwis
You could phrase this in most dialects of SQL, but you don't say what kind of
database you are using and this is not a SQL help list.
You could also look at the rollapply function in the zoo package.

Add geom_errorbar() before adding geom_point() ?

I think (no promises) roll.apply() from the zoo package with sum can count
occurrences in whatever time period. Then use a logical test to identify
sufficiently active periods.
Hope this helps,

Hi Jeff,
My question is not related with SQL.
I have all the data available in a csv file.
I am looking for R algorithm where can specify a time period and then R
essentially uses this time period as a sliding window for all the event-time
stamps and gives
a significant distribution of occ
Hi, Jesper:
Where "Outside R" do you want to use it?
There are R interfaces to many other software packages, and many
that cannot easily link to R can link to Fortran. You could use
library(sos) to search for R packages to connect to whatever.
Hope this helps.
