?rbinom
Each probability distribution in R has an r*** function (for “random”), a d***
function (for “density”), a p*** (for “probability”), and q*** (for
“quantile”). We are most interested in the r*** functions in this lesson, but
I encourage you to explore the others on your own. | |

R_base_all/index.html6_27_0.txt | The above code will set ` rand_number_1 ` to a randomly selected value, in
this case 3. Because we have not specified a probability vector ` prob ` , the
function assumes that every element in ` 1:10 ` is sampled with equal
probability. We can increase the ` size ` of the sample to ` 10 ` below.

then bind them together via ` data.frame() ` .
Notice there is no need to use ` cbind() ` here, which is commonly done by R
beginners (I know I did!). Instead we can use ` data.frame() ` directly. | |
