[R] Average value in a particular range of a matrix

Hi I have a matrix with values of size 1*500 i have to find the avg value of first 1 to 100 ,avg value of 100 - 200 and so on up to 400-500. is there any function to find the average of 1 -100 and 100 - 200, 200 - 300,300 - 400,400 - 500 ?? Thanks
