The reasons are
1. x might be the result of an expression. Without value=
one
Try redefining quantile.default:
environment(quantile.default) - .GlobalEnv
For example, if you run the following in a fresh session it should
print out X showing that the newly defined sort was invoked:
environment(quantile.default) - .GlobalEnv
sort - function(x, ...)

yourself.

One final question ...

See the help desk article in R News 4/1 for more about the main
date classes.

I found a web page that said to upload using ftp to cran.r-

Can you upload things into incoming? Perhaps there is simply
something funny about my ftp client? I will try from my MacOSX box
once more just to check.

The key issue is inheritance. If you use a data frame with attributes then
you can inherit data frame methods without further definition,
e.g.
x - structure(data.frame(a = 1:10), my.attr = 33,
class = c(myclass, data.frame))
dim(x) # inherit dim method
but if you do it this way

On Windows XP either of these work under R. Here echo and findstr
are builtin Windows commands but you could substitute others:
system(cmd /c echo abc | findstr a, intern = TRUE)
shell(echo abc | findstr a, intern = TRUE)
If its necessary to special case it then note that the

As others have mentioned its not really a good idea
to modify the namespace of a package and writing
a wrapper as Duncan suggested is much preferable.
An intermediate approach that
is not as good as the wrapper but better than modifying
the namespace is to copy the objects of interest
