[R] Dataframe with different lengths

[Ulrik Stervbo]

Hi Pedro,

I see you use dplyr and ggplot2. Are you looking for something like 
this:

```
library(ggplot2)
library(dplyr)

test_data <- data.frame(
   year = c(rep("2018", 10), rep("2019", 8), rep("2020", 6)),
   value = sample(c(1:100), 24)
)

test_data <- test_data %>%
   group_by(year) %>%
   mutate(cumsum_value = cumsum(value),
          x_pos = 1:n())

ggplot(test_data) +
   aes(x = x_pos, y = cumsum_value, colour = year) +
   geom_point()
```

Best,
Ulrik
