missing factor levels in a lattice barchart panel cause unexpected failure
Hi all - I'm trying to generate lattice barchart graphs with missing
values, and came across the following:
This does not run. I would expect it to:
library(lattice)
D = data.frame(X=1, Y=factor(letters[2], letters[1:2]))
barchart(~ X, D, groups=Y)
Error in grid.Call.graphics("L_rect", x$x, x$y, x$width, x$height,

libFLAC bitbuffer optimizations
Pulled from my Arch archive, this following patch seems to have made
quite a difference in getting my ARM7TDMI chip to play FLAC (compression
levels 0-2) on my ipod. I don't have benchmarks with hard numbers, but
playing with skips vs playing without skips is a fairly noticeable
difference.
memcpy and memset on uClibc are optimized in asm for the ARM7TDMI in
uClibc. Other hardware/libc

Ok, here is a patch waiting for new CVS :). It works fine for me, but
please check it before commiting...

Lattice: arbitrary abline in multiple histograms
Dear list.
I have three histograms and I want to add a vertical abline in a different
place in each plot. The next example will plot a vertical line at x=5.5 in
the three plots:
rnorm(100,5,3) -> A
rnorm(100,7,3) -> B
rnorm(100,4,1) -> C
rep(c("A","B","C"),each=100) -> grp
data.frame(G=grp,D=c(A,B,C)) -> data
histogram(~ D | G, data=data,

bitreader optimizations
Hi,
attached are patches that improve decoding speed a bit. The first
patch improves the bit scan macro used for decoding unary values, the
second one adds a GCC inline assembly for bswap and the third patch
replaces the read_rice_block function.
In my testing it turned out to be even faster than the _ia32_bswap
function. If the code produced by MSVC is faster as well, I'd suggest
to remove

barchart (lattice) with text labels
I would like to place the value for each bar in barchart (lattice) at
the top of each bar. Something like the following code produces.

panel.barchart(x, y, ...)
panel.text(x, y, labels=as.character(round(x,2)), ...)

MATLAB vrs. R
I need to find the area under a trapezoid for a research-related project. I was able to find the area under the trapezoid in MATLAB using the code:
function [int] = myquadrature(f,a,b)
% user-defined quadrature function
% integrate data f from x=a to x=b assuming f is equally spaced over the interval
% use type

histogram method for S4 class.
Hi,
I'm trying to develop an histogram method for a class called "FLQuant"
which is used by the package FLCore (http://flr-project.org). FLQuant is
an extension to "array". There is an as.data.frame method that coerces
flquant into a data.frame suitable for lattice plotting. The problem is
that when I coerce the object and plot it after it works but if the

Draw a nomogram after glm
Hi all R users
I did a logistic regression with my binary variable Y (0/1) and 2
explanatory variables.
Now I try to draw my nomogram with predictive value. I visited the help of R
but I have problem to understand well the example. When I use glm fonction,
I have a problem, thus I use lrm. My code is:
modele<-lrm(Y~L+P,data=donnee)
fun<- function(x) plogis(x-modele$coef[1]+modele$coef[2])

(I sent this earlier, but it seems not to have come through, due to
problems witkh my system)
The following command from appendix A, "a sample session", isnt correct:

when used R protests:
Warning message:
parameter "nint" couldn't be set in high-level plot() function
it should probably be nlevels, as used a few lines before.

lattice histogram problem with integers values and nint
been puzzling over this for a day.
Summary
integer variable to use with histogram, 170,000 rows. Value is day of
year. Hist works, lattice histogram with nint does not work (spurious
spikes in display), lattice histogram using breaks=c(0:365) works
fine. Spike values appear to be sum of two adjacent bins. Want to
know if this is a familiar problem, and what the recommended
work-around is.

Dropping 'empty' panels from lattice
I have 8 cofactors possibly affecting one and only one variable.
I make conditional histograms:

Groups in histograms?
Dear list,
I would like to create histograms for up to three groups, with
distincive colour/pattern, in a trellis panel. However, I have not
been able to find a way to do this. histogram does not seem to have a
group argument.
Please help.

Trapezoid Rule
Dear R Users,
I've never used R before and my professor has asked us to do some
pretty intense programming (or it's intense to me at least). Here is
the question: Modify the function myquadrature inside the script so
that it returns the quadrature of descrete data using the trapezoidal
rule. Modify the call to the function at the bottom of the script so
that is uses your modifies
