[R] How to quieten axis() for Sweave: avoid echoing NULL?
Dear R-community,
I'm using Sweave to produce reports. The reports require the axis
command. When I run axis the program returns NULL as well as creating
the axis.
plot(1:4, rnorm(4), axes=FALSE)
axis(1, 1:4, LETTERS[1:4])
NULL
So, my Sweave tex files have
\begin{Schunk}
\begin{Soutput}
NULL
\end{Soutput}
\end{Schunk}
in front of each graphic that requires axis. I can easily find them
and remove them, but I was wondering: is it something I can avoid? Or
am I doing something foolish and obvious?
Thanks for any assistance,
Andrew

Hi!
The following works for me:
\begin{figure}
\centering
fig1.R,fig=true,echo=false=
plot(1:4, rnorm(4), axes=FALSE)
axis(1, 1:4, LETTERS[1:4])
@
\caption{Plot test}
\label{fig:1}
\end{figure}
I'm using R 2.0.1 on an i686 with GNU/Linux Ubuntu 4.10.

I think this qualifies as a bug along with similar issues with
title(), text(), and mtext(). They all end with .Internal calls
producing NULL. Once upon a time, they did so invisibly, but somehow
this changed.
The simple workaround is to wrap the call in invisible().

[R] Black and white graphics and transparent strip panels with lattice under Sweave
What is the most elegant way to specify that strip panels are to have transparent backgrounds and graphs are to be in black and white when lattice is being used with Sweave? I would prefer a global option that stays in effect for multiple plots. If this is best done with a theme, does anyone have a lattice theme like col.whitebg but that is for black and white? I'm using the following with lattice 0.10-16, grid 2.0.0: platform i586-mandrake-linux-gnu arch i586 os linux-gnu system i586, linux-gnu status major2 minor0.0 year 2004 month10 day 04 language R Thanks, Frank -- Frank E Harrell Jr Professor and Chair School of Medicine Department of Biostatistics Vanderbilt University __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

Re: [R] subsetting within a function
Thankyou for your help with subsetting within a function. I have now tried
to apply the same theory in the framework of an lme as follows:
fit1.lme - eval(substitute(lme(fixed=fixed, data=dataframe,
random=random, correlation=corCAR1(form= corr), na.action=na.omit,
subset=subset),list(subset=subs)))
but I get the following error:
Error in switch(mode(object), name = , numeric = , call = object,
character = as.name(object), :
[[ cannot be of mode logical
I'm not sure why. Can anyone help me with this?
kind regards
Pam

And so my attempt to wrap a simple function around this looks like:
test.fun - function(formula, mydata, sub=NULL){
subs - with(mydata, eval(sub))
fit.glm - glm(formula=formula, data=mydata, family=binomial, subset=subs)
return(fit.glm)
}
But when I tested it out with
test - test.fun(y~x1+x2, mydata=testdata, sub=expression(SEX==0))
I get:
Error in [.data.frame(structure(list(N_ASTHMA = as.integer(c(0, 0, 0, :

I get a different error: it may be that you have an object called `subs`
in the global environment
I'm guessing that it's looking in the global environment for
subs,
More precisely, it is looking in environment where `formula` was created,
which happens to be the global environment.
This is the sort of thing that happens with the fitting functions because
they go to such lengths to break the basic scoping of R.
You probably have to substitute() the evaluated subset into the glm call.
fit.glm - eval(substitute(glm(formula=formula, data=mydata,
family=binomial, subset=subset),list(subset=subs)))

[R] matrix and error in points, plot ?
Hi, Would a specialist of the point or plot functions try the following: mat-matrix(c(1.836767,4.025989,0.6396777,0.376),ncol=2) plot(mat) points(mat[1,],col=red) ..A lag appears on x for mat [1,1] between the two displays. I wonder if this example may be due to a bug or to the mis-use of a matrix in the plot() points() functions. In case of mise-use which kind can it be? I am working with R 2.0.1 and Windows XP.
