logical(0) response from lrm
What causes the error report:
logical(0)
to arise in the rms function lrm?
Here's my data:
But both the dependent and the independent variable seem fine...

Regular expressions: offsets of groups
Dear list!
> gregexpr("a+(b+)", "abcdaabbc")
[[1]]
[1] 1 5
attr(,"match.length")
[1] 2 4
What I want is the offsets of the matches for the group (b+), i.e. 2
and 7, not the offsets of the complete matches. Is there a way in R
to get that?
I know about gsubgn and strapply, but they only give me the strings
matched by groups not their offsets.

Validating alignment of NTFS/VMDK/ZFS blocks
Good evening,
I understand that NTFS & VMDK do not relate to Solaris or ZFS, but I was wondering if anyone has any experience of checking the alignment of data blocks through that stack?
I have a VMware ESX 4.0 host using storage presented over NFS from ZFS filesystems (recordsize 4KB). Within virtual machine VMDK files, I have formatted NTFS filesystems, block size 4KB. Dedup is turned on.

deparse operators in expressions
Hi,
I observed a slight problem in deparse(): it will add spaces around
most operators except /. I wonder if this is easy to fix. I know this
is quite trivial, but I will appreciate if / is not treated as an
exception. Examples:
> deparse(expression(1/1))
[1] "expression(1/1)"
> deparse(expression(1+1))
[1] "expression(1 + 1)"
> deparse(expression(1%in%1))

How to pass a character argument which contains expressions to arg.names in barplot?
Hi all
Can anybody help me with this? I am trying to include in an automatic way
the argument in arg.names in a barplot. I generate the labels I want to
appear below the bars with a for loop, and they contain subscripts, so I
need to use expression
anch<-0.05
esp<-4
for (i in 1:dim(Ntot)[1])
{
naux<-Ntot[i,]
naux2<-naux[naux>0]

combining mathematical notation and value substitution
Dear People,
I need to make a label which both contains math notation as well as
substitutes a value for an object. In the following label, len and theta
are one dim variables, and I am substituting their values appropriately.
This label looks fine except that I want the greek symbol for theta to
appear instead of the word `theta'. How can I do so most easily? I don't
understand the

Reconstruction of a "valid" expression within a function
Hello all,
I have some trouble in reconstructing a valid expression within a
function,
here is my question.
I am building a function :
SUB<-function(DF,subset=TRUE) {
#where DF is a data frame, with Var1, Var2, Fact1, Fact2, Fact3
#and subset would be an expression, eg. Fact3 == 1
#in a first time I want to build a subset from DF
#I managed to, with an expression like eg. DF$Fact3,

Expressions and Functions
Dear R People:
When the D function is used for a symbolic derivative,
an expression is returned, which is fine.
How do you change that expression to a function, please?
I've been experimenting with substitute and deparse, but no success
yet.
This is R 1.8.0 for Windows.
thanks in advance for the help!
Sincerely,

missing symbols for mathplot
Hi all,
I'm trying to write an axis label
that sounds P( X | K and Xb ) (probability of X given K and Xb )
but I need the intersection symbol
(the "\cap" in latex)
Actually I did'nt find any "cap" symbol
in plotmath, the only one is
intersect(A[i],i==1,n)
but is not my case because subscripts and arguments are mandatory.
Anyone knows how to do?
Thanks

Detailed legend in mathplot ...
Hello,
Recently, I have asked for a help with building graphs, and I got few
great advices. Now, my appetite is growing :) and I wander how to add
legend for two (or more) lines in following example:

+ pch=c(21,22), col="black", lty=c("dashed","solid"), xlab="",

variable value in mathplot
I'm putting a title over different plots, where 'that'

linebreaks in mathplot
Dear HelpeRs,
I would like to do sg similar to:
plot(c(0,100), c(0,100), xaxs="i", yaxs="i", type="n")
txt <- paste("a =", a, "%\n b =", b, " km2", sep="")
text(95, 95, txt, adj=c(1,1))
just with the "km2" formatted with 2 in a superscript.
I thought
txt <- substitute("a = "*a*" %\n b

ssh -R limitations?
Hi there!
I've a couple of questions on -R feature:
Here is my situation:
PC_A has a private IP, ssh client and has a service I want to see from the
internet.
PC_B is a linux firewall (public IP) where there is an open port that
forwards all traffic to PC_C (ssh server on port 22) which is in PC_B LAN.
I want to create a tunnel from PC_A to PC_C to access a service on PC_A from

formula argument evaluation
%=>% would have precendence ('order of operations') problems also.
A + B %=>% C
is equivalent to
A + ( B %=>% C)
and I don't think that is what you want.
as.list(quote(A + B %=>% C)) shows the first branch in the parse tree. The
following function, str.language, shows the entire parse tree, as in

cbind(deparse.level=2,...) problems
Should the deparse.level=2 argument to cbind
and rbind be abandoned? It is minimally documented,
not used in any CRAN package, and causes some problems.
E.g.,
(a) If a matrix input has row names but not column names
cbind(deparse.level=2,...) stops.

can non-owner change file group setup?
We are tried to count how many files belong to certain group. Our system administrator told us "non-owner" can easy change file group name to another. I have been tried several combination and never successful (only ROOT can change file group to other name).
Does anyone know how "no-owner" can change file group name?
Thanks.
