Parameter plots in R

I am trying to produce a plot using ggplot2 on the UNvotes data. I am trying to parameterize the plot in Rmarkdown but getting the following error:

Error: Problem with `summarise()` input `perc_yes`. x non-numeric argument to binary operator i Input `perc_yes` is `sum(vote == "yes")/n`. i The error occurred in group 1: yr = 1991.

Code:

single_country %>% 
  inner_join(un_roll_calls %>% select(rcid, date), by = "rcid") %>%
  mutate(yr = year(date)) %>%
  group_by(yr) %>%
  summarize(perc_yes = sum(vote == "yes") / n) %>%
  ggplot(aes(x = yr, y = perc_yes)) + 
  geom_point() +
  geom_line() + 
  labs(title = plot_title)

Not sure if it is lacking some recoding issues or so.

Change this line before ggplot

summarise(perc_yes = sum(vote == "yes") / n) %>%

with this line:

summarise(n = n(), perc_yes = sum(vote == "yes") / n) %>%

Actually you are missing n = n()
