Convert data frame into vector

I have a one row/column dataframe that I would like to convert into a value. 

df <- data.table(x=c(300))
>#     x
># 1: 300

I've managed to do it by doing this:

b <- as.list(df)[[1]]
># [1] 300

so that identical(b, 300) == T

Is there a simpler way to achieve this? I understand this is a very simple question but I couldn't find a solution. Help?

Instead of using unlist, you can also simply do:

x <- df$x

the result is a normal vector with the values from x:

> x
[1] 300

Basically, data frames are lists, so that you can invoke unlist(df).
