[R] Converting from density to cumulative distribution

Hello I'm trying to do the following vector operation: given vector x = c(x1,x2,x3,x4...xn), produce vector y = c(x1,x1+x2,x1+x2+x3,...x1+...+xn). E.g., from x = c(1,3,2,2,5), produce y = c(1,4,6,8,13). The underlying problem is finding the cumulative distribution function given the em
