You could try rescaler in the reshape package. It currently suppor
Hi,
I'm working on producing a simple cumulative frequency

Thanks to the help of the good people on this list I
now have four vectors that I'd like to join/relate
into a table. e.g.

v2 <- myHistogram$counts # freqs

I have a dataframe where I would like to order first
by variable, year, and then within that variable by
month.
So far the only way that I have seen to do this is to
order by year and then subset year and sort by month
and then do an rbind to get things back together.
Is this the right approac

try the following:
mdf <- data.frame(us.state, count, year, month)
mdf[order(mdf$year, mdf$month), ]
I hope it helps.

Have you considered the 'nlme' package, well documented in Pinheiro
and Bates (2000) Mixed-Effects Models in S and S-Plus (Springer)?
Hope this helps.

Hello,
How do I split a y-axis to plot data on different scales?
Eg:
x <- 1:10
y <- c(-0.01,0.79,0.74,0.55,-0.67,0.32,-0.47,-0.05,723,759)
plot(x,y)
I'd like to show these data on the same plot, but the way it's written, all
contrast in the first 8 data points is lost. Can R split a y-axis for
> How do I split a y-axis to plot data on different scales?
The short answer: you shouldn't. The whole point of plotting the data
is so that you can compare them visually on the same scale. As soon
as you split the scales you can no longer do this, and you effectively
have two separate graphs.

The source of the problem is that lmeSplines requires a set of iid random
effects corresponding to a transformed smoothing spline basis (`pdIdent'
structure in nlme) i.e. pdIdent(~Zs -1), where Zs is the transformed set of
spline basis functions. Kevin's model does not work because each of his

Ok, I had a look at it. It seems like awefully far to dig for the main point
which is easily
summarized in a few sentences.
If we super-impose the pre-image and image spaces (plot the input and output in
the same
picture), then in 1 dimension, a linear function, say 'a x', takes its input,

Hi: I have a large data set that I'm testing and I'm finding that
preplot.gam is taking a very long amount of time to compute (like, more
than 20 minutes). My machine is 32-bit, Debian unstable, 4GB memory,
dual Xeon 3GHz. While the data set is very large, the gam() procedure is
able to compute
