How do you normalize the local extremum?

R=[3	14	34	63	94	123	145	162	176	185	193	197	198	193	187	180	169	155
   138	120	100	78	55	34	14	2	0	0	0	1	2	1	0	0	2	23
   55	92	123	148	170	185	198	204	200	186	158	121	81	42	14	0	0	0
   0	1	6	14	20	26	38	61	91	123	147	164	172	171	165	143	101	54

I want to know how to get the peak-to-peak values to be the same.

How to normalize curves with multiple peaks such that each peak will be 1 and each valley will be -1 ？

%%%% y is original data
%%%% max(i) is local maximum;min(i) is local minimum

This is a formula I found. This is a challenge for me and I haven't overcome it yet.
