Hello,
What about an `invert` argument in grep, to return elements that are
*not* matching a regular expression :
R> grep("pink", colors(), invert = TRUE, value = TRUE)
would essentially return the same as :
R> colors() [ - grep("pink", colors()) ]
I'm attaching the files that I modified (

Hi everyone,
Firstly, I'm sorry for the cross-post. I re-read the posting guide
and it appears my question is more related to r-devel (i think :-) )
I downloaded the source code available at:
http://cran.fhcrc.org/src/base/R-2/R-2.4.0.tar.gz
to a linux machine (Linux 2.6.11-1.1369_FC4smp

probably you're looking for:
f <- function(FUN, x){
list(funName = deparse(substitute(FUN)), value = FUN(x))
}
f(mean, rnorm(10))
f(median, rnorm(10))
I hope it helps.

Hi,
Does anyone know how I can retrieve a function name, for example
If I have a function f as follows:
f <- function( myfunc ) {
print( name_of(myfunc) );
}
I want to know what I should have as "name_of" such that I could call this
with :
f( median )
and it would print "media
Hi,
When x is a data frame, sample(x) is not really sensible :
R> sample(iris) # sends back all the iris data set.
What about a generic sample function (from R-devel/src/library/base/R)
with a method for class `data.frame` that would sample the row indexes
and then do the subset. See the code
