Examples

# NOT RUN {
library(ggplot2)
library(dplyr)
data(statsbomb)

# normalise data, get non-penalty shots for France, 
# add boolean variable 'goal' for plotting
my_df <- statsbomb %>%
  soccerTransform(method = 'statsbomb') %>% 
  filter(team.name == "France" &
         type.name == "Shot" &
         shot.type.name != 'penalty') %>%
  mutate(goal = as.factor(if_else(shot.outcome.name == "Goal", 1, 0)))
  
soccerPitchHalf(data = my_df, theme = 'light') +
  geom_point(aes(x = location.y, y = location.x,
                 size = shot.statsbomb_xg, colour = goal),
             alpha = 0.7)
