library(tidyr)

# data into tidy format for plotting
df0 <- sweden1993 %>%
  select(age, Nx_m, Nx_f) %>%
  gather(key = gender, value = pop, -age) %>%
  mutate(gender = gsub("Nx_", "", gender))
df0

# plot
pyramid(data = df0,
        gender_lab = c("f","m"),
        age_col = "age", gender_col = "gender", pop_col = "pop")
