I got this data, but when i use mutate(acc_growth_p1 = accumulate(1+port1, '*')), I am not getting the cumulative figure.

I tried to use mutate and them the accumulate, but I keep getting only the 1+port figure.

mutate(acc_growth_p1 = accumulate(1+port1, '*'))

mutate(acc_growth_p1 = cumprod(port1 + 1))

For example:

data.frame(rates = seq(0, 0.5, by = 0.1)) %>%
  mutate(growth = cumprod(rates + 1))

  rates growth
1   0.0 1.0000
2   0.1 1.1000
3   0.2 1.3200
4   0.3 1.7160
5   0.4 2.4024
6   0.5 3.6036
