Given this data:
data <- read.table(text="
age married house income gender class
1 22 0 0 28 1 0
2 46 0 1 32 0 0
3 24 1 1 24 1 0
4 23 0 1 40 0 1
5 50 1 1 28 0 1
")
Whenever I take a section of more than one value I also get the row and/or col names, eg:
> data[1, 1:2]
age married
1 22 0
Is there some way to drop any names and make this nameless (no labels) without explicitly setting anything to NULL beforehand (or loading in a file with row.names=F
etc.)?
The goal is just to be certain nothing is attached when something like nameless(..) is called.
# Not OK
colnames(data) <- NULL
data[1, 1:2]
# OK
nameless(data[1, 1:2])
[1] 22 0
Example:
output
[[1]]
income
4 36 2 3 NA
[[2]]
age
1 48 4 5 NA
Looks a bit silly, but what about:
unname(unlist(data[1, 1:2]))
#[1] 22 0
unlist()
has a use.names
argument that will drop the names.
unlist(data[1, 1:2], use.names = FALSE)
Or if everything being returned is of the same type you can use eg as.integer()
on it:
as.integer(data[1, 1:2])
Borrowing unname
from @alexwhan
unname(c(data1[1,1:2]))
[1] 22 0
