R中具有均匀分布元素的随机向量a

Question

I'm new to R and I'm looking through a book called "Discovering Statistics using R".

Although the book implies you don't need any statistical background, some of the content isn't covered/explained...

I'm wondering how you simulate a random vector a with 200 elements from the uniform distribution on the interval (-50, 50).

Maybe I'm unsure because of the terminology used. For the example I just created a vector with 200 elements that range inbetween -50 and 50... I'm just checking if this is correct.

Or is there a function that generates random values like there is in Java? I haven't found anything on google either regarding R providing random values.

Answer 1

runif(200, -50, 50)
