Files and classes in a package?
...Class("bclass", representation(j="numeric"))
When combining the source files, R seems to generate one new source file
based on alphabetic orders of file names. In this case, loading the "pkg"
package failed with the following error message.
> library(pkg)
Error in methodsPackageMetaName("C", name) :
The name of the object (e.g,. a class or generic function) to find
in the meta-data must be a single string (got an object of class "NULL")

correlation structures in NLME
...n structure with
the function corAR1 in NLME. This example is taken from the book of
Pinheiro and Bates, so it should work. What is going wrong?

S4 methods bug in naming of slots (PR#3665)
...ok", representation(
"A" = "matrix",
"C" = "matrix"))
new("notok",
"A" = diag(4),
"C" = diag(4))
It says
> new("notok",
+ "A" = diag(4),
+ "C" = diag(4))
Error in methodsPackageMetaName("C", name) :
The name of the object (e.g,. a class or generic function) to find in the meta-data must be a single string (got an object of class "matrix")
Can this bug be fixed? It doesn't work in the Windows version either.
Thanks in advance.

slot named C
...a slot in an S4 class (example
below). If this is a known limitation, and not a bug, it would be nice
if it were caught by setClass.

terms.formula
...qss(x), or qss(x,z). I need some
advice about strategy for formula processing. My initial foray
was to use:
terms(formula,specials="qss")
and then modify the components of the resulting
terms.object. But in changing formula at factors to drop the qss
columns and rows, I ran afoul of methodsPackageMetaName
which claimed that it was "being abused" by this.
if(!is.null(attr(formula,"specials"))){
qss.col <- pmatch("qss",attr(formula,"term.labels"))
qss.row <- formula at specials$qss
formula at factors <- formula at factors[-qss.row,...
