Replacing plot symbols w/ subject IDs in xyplot()
All,
How does one replace plot symbols with say subject IDs when using xyplot? Or
superimpose them next to plot symbols? I searched the archives under
various key words but haven't had much. Any suggestions or links much
appreciated. Sample code below.
David
junk.frm = data.frame(ID = rep(1:16, each = 2), x, y, z = rep(c("D", "P"),
16))
y = c( 0.4, 0.6, -0.1,

"symbol print-name too long"
All,
I've coded a function and it works manually if I copy it line by line into R.
However, when I try to "load" (copy and paste) the entire function into
R, I get the following error after the listed line of code:
+ N.j.list = lapply(rej.hyp, length)
Error: symbol print-name too long
Does anyone you know what this error means? Strangely, when I copy the
same line verbatim

Subsetting within xyplot()
All,
I'm having problems w/ a simple attempt to subset an xyplot.
The first plot below is a plot of y versus x for certain values of a third
categorical variable z. Now I'd like to further restrict this to certain
values of variable y. Neither of the two attempts below work. Any
suggestions much appreciated. (note: I don't want to merely use ylim since

Adding points on top of lines in xyplot

I'm trying to make a basic plot: data points superimposed upon the a line

[LLVMdev] Problem with missing support for non-zero contant initializers.
Hi all.
I'm working on a LLVM based compiler for the D programming language by
Walter Bright.
D allows static arrays up to 16MB in size. I'm initializing global
static arrays with a constant initializer. But D requires that (per
default) static arrays are initialized with the default initializer
for the element type. For float this happens to be NaN, so I cannot

plot of all.effects object
All,
I'm trying to plot an all.effects() object, as shown in the help for
all.effects and also Crawley's R book (p.178, 2007). The data has a repeated

Below is a reproducible example that yields the error message.

Basic plot question: Figure 1.1 Pinheiro & Bates
All,
Sorry for overly simplistic question, but I can't seem to remember how to
create the basic plot shown in Figure 1.1 of Pinheiro & Bates (2004; p.4).
The y-axis delineates a factor (Rail) while the x-axis displays the
distribution of a continuous variable (time) according to each level of the
factor. Didn't see it in archives but perhaps I'm not searching on correct
key words,

Summary statistics across factor levels
R users,
I intention is to calculate some summary statistics across factor
levels. I know that in Hmisc package there is a summary function which
produces neat summary statistics when using "cross" option. I would
like to produce similar output with N and Missing columns but produce
a data.frame. Is there any built-in function for that?

this?

Wireframe graph: black and white shading instead of color
All,
The code below produces a color 3D graph. I'd like to make it black and
white shading. I tried setting col.regions to FALSE but this just made it
completely white. I want the graph to look exactly as is, except black (or
grey) and white shading. Is this possible?

Lattice scales question: using "at" when log = TRUE
All,
I have a simple lattice plot where I have set log = TRUE for the y scale.
When I attempt to change the tick locations via the "at" argument within
scales, the supplied numeric vector is not followed. Any suggestions much
appreciated for the example below:
y = c(10^1.5, 10^2, 10^3, 10^2)
t = c(1,2,3,4)

Domain login delays w2k8 R2
Hello!
We have a w2k8 R2 64-bit machine in a Samba 3.4.4 controlled domain.
When logging in as a domain user there is a ~30 sec delay waiting
for the User Profile Service. This has nothing to do with the size
of the user profile. Looking at the network traffic I can see 2
gaps, the first about 11 sek and the second about 19 sek with
no packets sent except one TCP ACK (from the client) in each

how to control significant digits(?) on axis labels
Dear R mailing list
I would like some help on how to get R to display the same number of significant digits (?) for *all* tick marks on axis labels (yet be flexible enough to handle different data sets that vary by 10-1000X).
Consider this simple example:

2 significant digits
Hi,
How to represent a rounded number ending with 0 with 2-significant digits? If I have for ex, 0.8031 and I use signif or round with digits = 2, I'll get 0.8. If I use format, I get character type (even if I pass number as parameter) and if I convert with as.numeric, I'll lose one significant digit (0):
> format(13.7, nsmall = 2)
[1] "13.70"
> as.numeric( format(13.7,
