R-alpha: R-0.50-a3(+) Method despatching bug ?
It is very wierd... Can some of you confirm the following behavior ?
It is a new bug (feature ?) which was not yet in 0.49 ...

Class noquote to matrix
Hi,
I apologize if the solution is right in front of me, but I can't find anything on how to convert a class of 'noquote' to 'matrix'. I've tried as.matrix and I've tried coercing it by 'class(x)<-matrix', but of course that didn't work. I've been using the function 'symnum' which returns an object of class 'noquote'.
Here is an

normality and equal variance testing
I currently have a program that automates 2-way ANOVA on a series of endpoints,
but before the ANOVA is carried out I want the code to test the assumptions of
normality and equal variance and report along with each anova result in the
output file. How can I do this?
I have pasted below the code that I currently use.

Pass character vector to function argument
A bit embarrassed to post this seemingly trivial question, but I can't find anything in the archive that's quite relevant:
a1=1
a2=2
obs=objects(pattern=glob2rx("a?"))
I want to utilize 'obs' as a function argument to produce something like:
sum(a1,a2)
Obviously, sum(obs) doesn't work, but I've tried variations of 'eval', 'parse',

Passing a list object to lapply
Hello,
I'm having difficulty passing an object name to a lapply function. Can
somebody tell me the trick to make this work?

contar casos en un vector
Buenas noches, tengo dos vectores con nombres. El primero es largo,
nombreL, y el segundo corto, nombreC. Quiero contar cuantas veces
aparece alguno de los nombres del vector corto en el largo.
Lo que estoy haciendo es lo siguiente:
cuenta <- 0
topL <- length(nombreL)
topC <- length(nombreC)
for (i in 1:topL) {
for (j in 1:topC) {

c.noquote() weirdness
I haven't been able to get anywhere tracking this down. It seems that c.noquote() does
something strange with its third (and subsequent) parameters:
R-2.7.0 under NetBSD, R-2.6.0 under Solaris, and R-2.8.0 (unstable) (2008-06-10 r45893)
under WinXP, I get:
> c(noquote('z'), 'y', 'x', '*')
[1] z y x * x *

or:
> c(noquote('z'),

write text file as output without quotes
Hi R,
When I use the below to write the text file
try=data.frame(rep("a",5), rep("b",5))
write.table(try,"z:\\try.txt",row.names=F,col.names=F,sep="\t")
the output contains two columns with quotes! Is there a way to write
without quotes?
I tried
try[,1]=noquote(try[,1])
try[,2]=noquote(try[,2])
Thank you,
Regards,

selections using text strings (result of noquote)
G'day all,
I am trying to use a string as an argument in a selection but things are
not working as I expect, seems the selection is not seeing the expanded
string and I do not know how to make it. Perhaps the noquote class value
that is returned is the problem.
Here is an example.
> selection #this is my string
[1] "attackprogress$Se=='Toona ciliata [19825: JMM35]'"

Quotation marks hinder for loop
Dear mailing list members,
My question is maybe very basic, but I could not find the solution.
I would like to do the following things
1)
colnames(V1)[2] <- par$V2[1]
colnames(V2)[2] <- par$V2[2]
colnames(V3)[2] <- par$V2[3]
...
colnames(V37)[2] <- par$V2[37]
2)
V1 <- V1[,-1]
V2 <- V2[,-1]
V3 <- V3[,-1]
...
V37 <- V37[,-1]
3)
ms <- merge(V1,V2)
ms <- merge(ms,V3)

Can I improve the next program?

for (i in 1:topL) {
for (j in 1:topC) {

Looping of read.table and assignment
Dear all,
I am trying to read in and assign data from 50 tables in an automated fashion. I have the following code, which I created with the help of textbooks and the internet, but it only seems to read in the final data file over and over again. For example, when I type:> table_1951 I get the same values in the table as when I type> table_2000 despite the values in the source tables

R-alpha: (minor?) S-R inconsistency: NULL =~= list() -- useful is.ALL function
In S,
NULL
and
list()
are not the same.
In R they are (I think).
---------------------------------------------------
At least,
is.list(NULL) #-> 'F' in S; 'TRUE' in R
Yes: I had an instance where this broke correct S code:
match(c("xlab","ylab"), names(list(...)))
when '...' is empty,
gives an error in R,
but gives
c(NA,NA)
in S.

Using paste to create and evaluate a variable expression
Is it possible to use "paste" to write out an expression and evaluate it?
Suppose I want to add two vectors X1 and X2, defined as follows:
X1 <- 1:6
X2 <- 6:1
If I write the following it looks like what I want but is a character:
noquote(paste(paste("X", 1, sep = ""), paste("X", 2, sep = ""), sep = "+"))
Is there a way to tell R
