For example 0 will be selected with probability 0.4 and 1 with 0.6. I could use sample function i.e. sample(c(0,1), 30, T) to get this, however here, selection of either 0 or 1 has equal probability here. I am looking for a function which can do the same thing but with different probabilities.

either ?sample (see "prob" argument), or ?rbinom
