documenting yoru progress
Hello all:
I have a function that writes a fairly elaborate report based on some
survey data. For documentation and bookkeeping purposes, I'd like to
write out in the report the function call that produced the report, or
at least enough information to help me recreate the steps that led to
that report. I've been generating all the reports with scripts, in
order to be able to recreate

avoiding a loop?
Hi All:
I feel like there must be a slick R-native no-loop way to get the counts
for the entries in a factor, but I'm unable to see how. Right now I'm
doing this:
hn.ent<-data.frame(rep(0,length(levels(hnf))), row.names=levels(hnf))
colnames(hn.ent)<-c("count")
for (lev in levels(hnf)) {
hn.ent[lev,"count"] <- sum(lev == hnf)
}
I'm sure there's a

vector sprintf argument
Hello all:
If I have a vector and a format, I want to do this:
> A <- c(3,4,5)
> F <- "Number: %d, %d, %d"
> sprintf(F,A)
This doesn't work because A isn't three arguments, it's just one. Is
there a way to peel the vector members out of A so that sprintf can get
at them?
I would like to do this because I have a large set of variable-length
data that

curvilinear grid
Hello all:
A question from a new user. I have data on a geo-referenced curvilinear
grid. This is a grid with 75 rows and 51 columns, is not aligned
north-south, and the rows and columns are not straight. (And the
coordinates are in meters.) I want to make image plots of this data,
but where the grid is deformed according to the correct locations of the
grid points, instead of coming out

data shape
Hello:
I have been give a spreadsheet to work with formed as one big table.
What it consists of is a 10-row-by-40-column table for each of about 70
different locations. In other words, the table row names are repeated
70 times, once for each of the locations (whose names also appear in the
same column, where it's talking about the totals for that location), e.g.:

ASR Suggestions for small dictionnary (<1000 entries) lookup in France/french
Hello,
I'm in the early stages of designing an Emergency calling service IVR
application.
The IVR application asks simple one or two questions like "which is the
postal code of the area you are currently calling from ?" "Is the correct
?". The expected values are a 5-digits number like
"twenty-five-thousand-two-hundreds-twelve" or

Max Number of #include statements
What's the maximum number of #include statments I can have in extensions.conf?
I'm getting an error at the 11th one. I tried breaking twelve #include's into 2 different contexts, and still got the same error. These aren't nested includes... they're only one level deep.
Thanks,
Doug.

date.to_s trimming
When I convert a datetime to a string, it prints out something like this
Jan 20 12:00:00 EST 2006
I want to trim off the last twelve characters, i.e.
:00 EST 2006
I tried to do it like so:
@date =
@meeting.date.to_s.chomp.chomp.chomp.chomp.chomp.chomp.chomp.chomp.chomp.chomp.chomp.chomp
but the chomps seem to do nothing. I''d love to use regex, but I don''t

Rails and Lighttpd, hangs?
I know this is kind of a generic question. But, when hitting my
lighttpd/rails site on some of the first hits, the site hangs. I
think it has something with the lighttpd configuration, possibly
something I am missing with rails or ruby? Any ideas or how to track
this down.

R-help Digest, Vol 91, Issue 21
All
Is there a script in R equivalent to the "if then" transforms one can
perform in Systat? For example, I want to create a "Treatment" column
coded either 1 or 2 for twelve field sites in a large data set. Ideally,
I'd be able to tell R to code sites a-f as 1 and sites g-l as 2.
Cheers

non-parametric Anova and tukeyHSD
I have insect data from twelve sites and like most environmental data
it is non-normal mostly. I would like to preform an anova and a means
seperation like tukey's HSD in a nonparametric sense (on some sort of
central tendency measure - median?). I am searching around at this
time on the internet. Any suggestions, books, etc. would be greatly
appreciated.

here are the steps we followed:

Audio Output Timer Utility
We have several CentOS 6.x systems that are incorporated into

Today is the last day of mediocre library call optimizations
To this day, we still do too little when it comes to optimizing well
known library calls.
Given that various libraries, especially the C/C++ standard library, are
relatively clear defined, and LLVM has all the infrastructure already in
place, e.g., SimplifyLibCalls.cpp, it seems odd that we still miss so
many optimization opportunities.
To show how easy it is, and how much impact it can have, I

RODBC & POSIX & Daylight Saving blues
Dear All,
The recent improvement in RODBC to recognize datetimes in tables has
exposed my ongoing confusion.
All my data are obtained from a satellite system (Argos) which tags events
in the GMT time zone. Daylight saving is ignored. To my way of thinking
this means that
1. twelve-o-clock means halfway through the day regardless of season, and
2. the difftime of any two dates where

Problems with "predict" function
Hello,
I am synthesising some sales data over a twelve month period, and then trying to
use the "predict" function, firstly to generate a thirteenth month forecast with
upper and lower 95% confidence limits. So far so good
But what I then want to do is add the upper sales value at the 95th confidence
limit to the vector of thirteen months and their respective sales to create a

na.action in model.tables and TukeyHSD
Hello everybody!
I use R 1.6.2 in Windows, and have a problem controlling the na.action.
In a dataset with twelve trials, one of the trials lack any readings of the variable "STS.SH" (standing power at harvest)
Fitting an aov() object with the call:
led1t7sts.aov <- aov(STS.SH ~ Trial/Block + Treatment + Treatment:Trial, data = led1t7, na.action=na.exclude)
