Hi Benilton
I actually tried "names(df) <- NULL" before I asked for help. Please see below
how it looks like
> names(df) <- NULL
> df
structure(c("chr1", "chr2", "chr3"), class = "AsIs") structure(c("1", "2",
"3"), class = "AsIs")
1 chr1
1
2 chr2
2
3 chr3
3
structure(c("4", "5", "6"), class = "AsIs") structure(c("7", "8", "9"), class
= "AsIs")
1 4
7
2 5
8
3 6
9

Subject: Re: [R] remove column names from a data frame
apparently
you
want
to
check
the
"Introduction
to
R"
document....
I
found
it
very
useful
when
I
started
working
with
R:
http://cran.r-project.org/doc/manuals/R-intro.pdf
try:
names(df)
<-
NULL
b
ps:
"df"
is
the
name
of
the
function
to
get
the
density
for
an
F
distribution...
