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)

Using xtable with summaries of lm objects
Hi all
Suppose I do the following:
set.seed(1000)
library(xtable)
x <- runif( 10 )
y <- 1 + 2*x + rnorm( length(x) )
test.lm <- lm( y ~ x )
summary( test.lm )
xtable ( summary( test.lm ) )
The final xtable output follows:

Sweave - print \n ?
Hi,
this is probably quite stupid but I have no clue
what's wrong. Let's say I write the function
hline <- function() {
cat("\\hline \n")
}
and call hline() from within a Sweave chunk. Why is
there no carriage return after the \hline in the
resulting tex file?
if I call hline() hline() in the chunk, then I get
\hline \hline
in the tex code without a linebreak in

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"

xtable with \begin{tabular} and only.contents
I have found that I like having my captions and labels in my latex document
rather than having them contained in my xtable output file (I haven't fully
gone to sweave yet). I know I can do something like this by using the
'only.contents' argument in xtable. Unfortunately, the only.contents
argument also removes the \begin{tabular}{rrrrrr} & \end{tabular} (in the
example below) of

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:

Problem setting the number of digits in xtable
DEar list members,
I am currently using Sweave with LaTeX which is great.
I can use xtable for formatting outp of tables but I have a problem setting the number of decimals in xtables when used with dataframe.
I have found an example on the net ith matrix and it works.
For example this works :
> > tmp <- matrix(rnorm(9), 3, 3)
> > xtmp <- xtable(tmp)
> > digits(xtmp)

paste in xtable
Dear R help:
I am trying to use paste(), within an ifelse() statement to insert latex
commands into an object that has been created using xtable(). I cannot
make the strings behave as I would like, the '\t' is creating a tab, the
usual method of '\\t' is not working either - nor is any series of
backslashes. The xtable object, I think, automatically alters the
strings. How

How to get '\h' through print() or paste()?
Hello,
[really hoping not to ask something the 1001th time]
I need single backslashes printed for generating TeX-code.
That works:
> print("\begin{tabular}")
[1] "\begin{tabular}"
But \h seems to be interprated in some way:
> print('\hline')
[1] "hline"
Hm, trying to mask the backslash:
> print('\\hline')
[1]
