Converting the row of a data.table to a vector

I want to turn data.table rows into vectors. Here's what worked for me:

unlist(dt[row_num])

But is there a more native solution? I also don't like that the above retains the name when really I want a pure numeric vector instead, which then leads to:

as.numeric(unlist(dt[row_num]))

Seems like there should be a better option.

The problem with extracting rows as vectors is that vectors are homogeneous while rows of data frames or data tables are not.

However, you can convert the data to a matrix then extract the row:

> x <- iris[1:10,1:4]
> as.matrix(x)[1,]
Sepal.Length  Sepal.Width Petal.Length  Petal.Width 
         5.1          3.5          1.4          0.2
