[R] Vector of string

Hi all. Suppose I have a vector of strings ie: [12384, TYU123123, AVC3939, hhr1919, TYU0029] Is there an efficient method that would allow me to return a vector of the position of strings that start with TYU? So essentially, I would like to get back in return [2, 5]. Anyways, any help with be
