random - How do I create a column with two values (or names) at a given weight in R

Question

I'm trying to create a column in my data in .dbf. I need to create a column in which 70% is 0 (or TRUE) and 30% is 1 (or FALSE), only at random.

How can I do this?

If you need for example 100 values, try this:

sample(c(0,1), size = 100, replace = TRUE, prob = c(0.7, 0.3))
