Really supress output from Sweave
Hi,
I am using Sweave for chapters in my thesis that contain results.
In the beginning of each chapter, I use this to load libraries I need.
<<init,echo=FALSE,quiet=TRUE>>=
library(gplots)
library(Hmisc)
library(e1071)
@
What I want is, of course, to supress messages written by this code,
but what I get in the end is X-init.tex with this the contents below.

library(its) problem
Dear R People:
I wanted to use the package "its" this afternoon.
I'm using R Version 2.2.0 for Windows.
I was able to install the package, but ran into trouble at
the "library" command. Here is the output:

describe function in package Hmisc and function format.dates in chron (PR#13087)
Full_Name: Kem Phillips
Version: 2.7.1 (2008-06-23)
OS: Windows Xp professional
Submission from: (NULL) (98.221.200.108)
The Hmisc function describe fails, giving the error message:
Error in formatDateTime(dd, atx, !timeUsed) :
could not find function "format.dates"
Loading the chron package, where function dates apparently resides, does not
fix the problem. Note

Sweave: trouble controlling Design package startup output
Hello, everybody:
I'm experimenting more with Sweave, R, and LyX. There's now an entry
in the LyX wiki on using R, so anybody can do it!
http://wiki.lyx.org/LyX/LyxWithRThroughSweave
Now I notice this frustrating thing. I think I've done everything
possible to make the Design library start up without any fanfare:

without the loop
Can this be re-implemented to run faster (without the loop) ?
r <- list()
n = nrow(prices)
for (i in (w+1):n) {
window <- prices[(i-w):(i-1),]
if (prices[i,]$settle > max(window$high)) r <-
append(r, 1)
else if (prices[i,]$settle < min(window$low)) r <-
append(r, -1)

seq in R
I want to generate a sequence from 1 to x by 1
seq(1,x,by=1)
I want the above to return an empty list if x is zero
In other languages I can do 1:x:1 to force the increment by to be a
positive 1. This syntax does not work in R. In R 1:x gives me
1 0
when x is zero, this is not what I want.
The seq statement above throws an error when x is 0.
How can I generate a sequence where if the

Too many open files
This may be more of an OS question ...
I have this call
r = get.hist.quote(symbol, start= format(start, "%Y-%m-%d"), end=
format(end, "%Y-%m-%d"))
which does a url request
in a loop and my program runs out of file handlers after few hundred
rotations. The error message is: 'Too many open files'. Other than
increasing the file handlers assigned to my process, is there

split number in a vector and then make a chron object out of it
These are date and times in the format YYYYMMDDhhmmss. I would like
to take this column and make a chron object form them. I have tried a
couple of the split family of functions but they need character input
here is the data:
date.time <- c(19851001001500, 19851001003000, 19851001004500, 19851001010000,

precision problem
I have prices that I am finding difficult to compare with ==, > and >,
due to precision. For example: the numbers should match, with '==',
but they differ in the magnitude of 1e-14 due to bunch of calculations
that I run on them. Programming with java, I am used to implementing a
function that compares the difference between the numbers to a pre
determined precision factor. This

how many 7th of the month is there between two dates
This is a eaeir way to ask my prior question:
I want to caculate how many an exact day of the month there is between
two dates.
For example; How many 7th of the month is there between "1998/12/17"
and "2000/1/7". To make the problem simple, the day of the month (7)
is the day in the 2nd date.

HMisc describe -- error with dates
Hello,
I am trying to use HMisc describe on a data frame. I have specified certain
variables as dates using, for example:
df1$aidsdate <- dates(aidsdate,format="day.mon.year", origin=c(month = 1,
day = 1, year = 1960))
When I use describe on the dataframe I get this error:
Error in Ops.dates(weights, x) : * not defined for chron objects
