Newbie q. need some help understanding this code.
dear all.
Would someone be kind and willing to explain the code
below for a person who has never used R? ( that is if
one has enough time and inclination)
It implements gillepsie's stochastic algorithm for
Lotka Volterra model.
What would help me tremendously is to see the
breakdown of the line by line code into plain english.
thanks for any insights or other comments.

Converting POSIXct vales to real values
I have a dataframe that contains time values in the form of yyyy-mm-dd hh:mm i.e. 2010-07-14 13:00. When I convert this to numeric via tvec <- as.numeric(Time) I get a number that is in seconds. So far so good. When I then divide the numeric value by the number of seconds in a day eg tvec/(60*60*24) I only get integer values and not fraction of a day which is what I want.

How to vectorize a function to handle two vectors
Dear R-users
I am trying to "vectorize" a function so that it can handle two vectors of
inputs. I want the function to use phi (a function), k[1] and t[1] for the
first price, and so on for the second, third and fourth price. I tried to do
the mapply, but I dont know how to specify to R what input I want to be
vectors (k and t)(see in the bottom what I tried). I have read the help

Likelihood returning inf values to optim(L-BFGS-B) other options?
Dear R-help list,
I am working on an optimization with R by evaluating a likelihood
function that contains lots of Gamma calculations (BGNBD: Hardie Fader
Lee 2005 Management Science). Since I am forced to implement lower
bounds for the four parameters included in the model, I chose the
optim() function mith L-BFGS-B as method. But the likelihood often
returns inf-values which L-BFGS-B

Having trouble using data returned by Ajax.request
Hello everyone, I''m new here.
I''ve been working with prototype and plotr for about a month now, off

nls - can't get published AICc and parameters
Hi
I'm trying to replicate Smith et al.'s
(http://www.sciencemag.org/content/330/6008/1216.abstract) findings by
fitting their Gompertz and logistic models to their data (given in
their supplement). I'm doing this as I want to then apply the
equations to my own data.
Try as a might, I can't quite replicate them. Any thoughts why are
much appreciated. I've tried contacting the

Convenience-at-the-expense-of-clarity (was: quantmod's addTA plotting functions)
Thanks, Writing plot(addTA()) worked fine.
I find myself with such mixed feelings about R. After finding that addTA
worked fine at the command line but not in a function, I puzzled for a long
time about what kind of virtual machine structure could possibly account for
that. I couldn't think of any.
It turns out that this isn't due to an R virtual machine structure. The
reason addTA adds

quantmod's addTA plotting functions
Hi,
I'm having trouble with quantmod's addTA plotting functions. They seem to
work fine when run from the command line. But when run inside a function,
only the last one run is visible. Here's an example.
test.addTA <- function(from = "2010-06-01") {
getSymbols("^GSPC", from = from)
GSPC.close <- GSPC[,"GSPC.Close"]

adding a dummy variable...
Hi all,
I have a dataset of individuals where the variable ID corresponds to the
identification of the household where the individual lives. rel.head stands
for the relationship with the household head. so rel.head=1 is the household
head, rel.head=2 is the spouse, rel.head=3 is the children.
Here is an example to see how it looks like:

Working with quantmod chartSeries and plot.zoo
Hi all,
I'm a newbie to R and it has been very helpful to use your website.
Unfortunately I've been struggling with my code now for two days so I wanted
to ask few questions. I've been trying to create nice graphs to put into a
pdf sheet but I'm having little problems with all the packages I've been
using. So what I want to accomplish is create one pdf sheet with three

[LLVMdev] gcc like attributes and annotations
hi all,
out of a matter of fact I am still using llvm version 1.5. I don't know
how 1.6 works in this matter.
When translating a complex c application to llvm bytecodes, some
semantics are lost:
Take for isntance the interesting attribute to put a variable in the
thread local data section (.tdata), this would be interesting to have in
llvm.
like in GCC you write:

abline(h=whatever) not working in candleChart() (in quantmod)?
Hello, all--
I am having some fun playing with the graphing in quantmod-- very nice! I am
writing a function to calculate (and hopefully plot) support and resistance
lines, but the usual plot call of "abline(h=value)" does not seem to work.
Here's my code:

ogg dirac granulepos in oggz tools
Hi,
I'm wondering if the Dirac granulepos parsing in liboggz and display
in the oggz tools is currently correct, as I'd like to do a release of
these soon.
A couple of days ago David Schleef mentioned there were some problems.
David, is that currently true (ie. since David Flynn's recent updates
to support Dirac), and if so could you please explain what the
problems are, or point me
