[R] Cumsum with a max and min value

I have a vector of values -1, 0, 1, say a - c(0, 1, 0, 1, 1, -1, -1, -1, 0, -1, -1) I want to create a vector of the cumulative sum of this, but I need to set a maximum and minimum value for the cumsum, for example: max_value - 2 min_value - -2 the expected result would be (0, 1,

Re: [R] Cumsum with a max and min value

Try this: ac - cumsum(a) ifelse(ac 2, max_value, ifelse(ac -2, min_value, ac)) On Thu, Nov 25, 2010 at 6:44 PM, henrique henri...@allianceasset.com.brwrote: I have a vector of values -1, 0, 1, say a - c(0, 1, 0, 1, 1, -1, -1, -1, 0, -1, -1) I want to create a vector of the

Re: [R] Cumsum with a max and min value

Does this do it; pmin(2, pmax(-2, cumsum(a))) [1] 0 1 1 2 2 2 1 0 0 -1 -2 On Thu, Nov 25, 2010 at 3:44 PM, henrique henri...@allianceasset.com.br wrote: I have a vector of values -1, 0, 1, say a - c(0, 1, 0, 1, 1, -1, -1, -1, 0, -1, -1) I want to create a vector of the
