Please answer this using R:

For each part below, give a single R command to complete the goal. Do not use c().

a.) Create a vector called seqvec that repeats the sequence 1 through 6 five times. (Grad students: work with the sequence 1, 3, 6, 10, 15, 21 instead)

b.) Create a 5-row, 6-column matrix from seqvec; each row should contain the sequence seqvec.

c.) Complete the two tasks above in a single step.
