This is unfortunately reinforced by the "(Not So) Short Introduction

document to learn about S4.

The problem is you can't lump together multiple S3 methods. Instead of:
> S3method(latex, anova.rms, bj, cph, Glm, Gls, lrm, naprint.delete, ols,

You need

S3method(latex, bj)
S3method(latex, cph)

Hi all,
In preparation for teaching a class next week, I've been reviewing R's
standard modelling algebra. I've used it for a long time and have a
pretty good intuitive feel for how it works, but would like to
understand more of the technical details. The best (online) reference
I've found so far

Ooops, missed that. So b %in% a = a:b, and that's what's meant by
"different coding".

So I guess my question then is how do data sets and namespaces

This is possible in ggplot2, but it's an not appropriate use of a bar
chart - because length is used to convey value, chopping the bottoms
of the bars of will give a misleading impression of the data.
Instead, use a dot plot:
data$Q <- unlist(lapply(data$Q, function(x) paste(strwrap(x, 20),

Hi Mark,
Try this to get you started:
table(roe1 > median(roe1), roe0 > median(roe0))

And the profr package for an alternative display.

ggplot2 is a plotting system for R, based on the grammar of graphics,
which tries to take the good parts of base and lattice graphics and
avoid bad parts. It takes care of many of the fiddly details
that make plotting a hassle (l

Hi Ian,
Have a look at the examples in http://had.co.nz/ggplot2/geom_tile.html
for some ideas on how to do this with ggplot2.

strings <- replicate(1e5, paste(sample(letters, 100, rep = T), collapse = ""))
system.time(strings[-1] == strings[-1e5])
# user system elapsed
# 0.016 0.000 0.017
So it takes ~1/100 of a second to do ~100,000 string comparisons. You
need to provide a reproducible example that illustrates

For a quick fix, you probably need to reinstall plyr.

However (as far as I am aware), note that this option is checked at
package build time, not at load time.
