I too have been studying the book and it is indeed outstanding.
For my purposes the only topic missing is the straightforward drawing of
error bars and bands, for which I've been using Hmisc::xYplot (where error
bands seem to be broken for R)

Hi,
I user barplot2 to make a plot bar with errors bars. In old times I needed to
use a sequence of segments commands to make this.
Now I try to make the same but using lattice. Is possible to use barplot2 in
barchart function?
Hi David,
Putting a print statement around your spplot command solves your
problem. This behaviour is common for trellis graphics plot methods
(such as spplot). This is the command including print:
print(spplot(meuse, c(ffreq),
sp.layout=list(l2,l3,l4,l5),col.regions=black,pch=c(1,2,3),
Since we're on the topic of book reviews, I just received Phil Spector's
new R book called Data Manipulation with R and it is also quite a
nice book. I haven't gone through it all and I won't give a detailed
review but I have gotten a lot out of the first 100 pages that I have
read.
Note
I would like to create a 3d scatterplot that is interactive in the sense
that I can spin it on its axes to better visualize some PCA results I have.
What are the options in R? I've looked at RGL and perhaps it will suffice
but it wasn't apparent from the documentation I found.
Any demo scripts

Dear R users,
I've had no joy finding a solution to this online or in any of my R books.
Many thanks in advance for any help you can give.
I'm seeking to output a data frame (or matrix - it doesn't matter which for
my purposes) to a .txt file, but omit any row or column names. The data
frame
try:
write.table(x, file=/Users/Desktop/Data.txt, row.names= FALSE, col.names=
FALSE, sep=, append=TRUE)
this should do it. If you don't want to append, just turn that opion off.

Hi Mark,
Try using ggobi via Rggobi. ggobi is aimed at higher dimension
multivariate data but it does a very useful service in 3-D projections,
do a manually controlled tour ... I've used this to tweak PCA results
and find fine structure,

Steve,
I think you can use:
write.table(x, file = /Users/Desktop/Data.txt, sep = , append=T,
row.names = F, col.names = F)
I used that for the data

If x is a zoo object note that zoo (and therefore dyn) allows the more compact
form lag(x, -(1:2)) so if we write:
mod.eq - x ~ lag(x, -(1:2))
then mod.eq[[3]][[3]] is the vector -(1:2) or if you like you can define
Lag - function(x, k) lag(x, -k) in which case you can write it:
mod.eq - x ~
Dear list:
I have a problem using the subset function:
dat- data.frame(treatment=c(A, B, A, C, C, D, A, D,
C, D), response=rnorm(10))
I am interested in treatments A, B and D
vec- c(A, B, D)
But I can only obtain what I want with:
subset(dat, treatment==A | treatment==B | treatment==D)
What's
Try %in%
subset(dat, treatment %in% vec)

That is precisely what I was after.
