Sweave issue: quotes in verbatim-like output print incorrectly
Hi all
I love Sweave; use it all the time.
But I recently received a new computer, and ever since I
have had a problem I've never seen before.
For example, I place the following in my Snw file:
<<>>=
sms <-
read.table("http://www.sci.usq.edu.au/staff/dunn/Datasets/applications/popular/smsspeed.dat",
header=TRUE)
attach(sms)

Problem using xtable on an array
Hi all
I know about producing a minimal example to show my problem. But I'm
having trouble producing a minimal example that displays this
behaviour, so please bear with me to begin with.
Observe: I create an array called model.mat. Some details on this:
> str(model.mat)
num [1:18, 1:4] -0.170 -0.304 -2.617 2.025 -1.610 ...
- attr(*, "dimnames")=List of 2

SMA and EMA in package TTR
Hi,
Just wondering for the SMA and EMA in package TTR, is it possible to me to
code it so that, say if I need to calculate SMA (x, n=100), when the sample
size is less than 100, it will give me the SMA (x, k) where k is the sample
size of the data? Right now it only gives me an invalid n error.
Thanks!

mcmapply Core Usage
Hello,
I have a minimal example that shows a problem I'm having with parallel processing.
library(parallel)
mcmapply(function(x, y)
{
print("Running")
Sys.sleep(10)
}, as.list(1:10), as.list(10:1), mc.cores = 16, SIMPLIFY = FALSE)
I see "Running" printed once every ten seconds. I read the documentation for mcmapply, but I don't understand why it wouldn't

Using bquote: question
Hi all
Observe:
x <- c(1,2)
y <- c(1,-1)
phi <- 1
p <- 2
par( mfrow=c(1,2))
plot(x , y, main=bquote( paste( p==.(p)," and ",phi==.(phi)) ) )
plot(y ~ x, main=bquote( paste( p==.(p)," and ",phi==.(phi)) ) )
par( mfrow=c(1,2))
On my system (details below), the first plot is correct (in my
understanding), and produces a title reading "p=2 and phi=1"

Producing a SMA signal when closing price is above the moving average for 3 days
I have loaded price data for GE and then calculated a 50 day simple moving
average. Then I have a created a ifelse statement that produce a 1 when
GE's closing price is above the simple moving average and a 0 when GE
Closing price is below the 50 day simple moving average.
However, what I really want to do is to produce a 1 for when the price is
above the simple moving average for 3 days

Random Count Generation with rnbinom
The documentation states :
An alternative parametrization (often used in ecology) is by the mean ?mu?, and ?size?, the dispersion parameter.
However, this fails :
> rnbinom(10, mu = 100, size = 0)
[1] NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN
Warning message:
In rnbinom(10, mu = 100, size = 0) : NAs produced
For dispersion set to 0, it should work like drawing from a Poisson distribution.

Strange behaviour of methods::slot() when returning a tibble
I have an S4 object class defined in a Bioconductor package which contains multiple slots, some of which are tibbles, whilst others are vectors. If I call
slot(object, name)
where 'name' is an slot that contains a vector, everything works as expected. However, when I call slot(object, name) where 'name' is an slot that contains a tibble I get the following warning:
