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...
