I have got his below code from the internet and trying to understand it. the code is as follows:
f_score_prob_matches <- function( missinggames, matchday30, foot_model, max_goals = 10, N, limit ){
all_final_tables <- data.frame(stringsAsFactors = FALSE)
clubs <- matchday30$club_name
conv <- numeric()
for(i in 1:N){
Goals_team_away <- 0
Goals_team_home <- 0
matchday30 <-
for (m in seq_along(missinggames$club_name_home)){
score_prob <- simulate_score_prob(foot_model = foot_model,
homeTeam = missinggames$club_name_home[m],
awayTeam = missinggames$club_name_away[m],
max_goals = max_goals)
score <- base::sample(x = score_prob, size = 1, prob = score_prob)
Goals_team_home[m] <- which(score_prob == score, arr.ind = T)[1]
Goals_team_away[m] <- which(score_prob == score, arr.ind = T)[2]
}
missinggames <- missinggames %>% mutate(Goals_team_home = Goals_team_home,
Goals_team_away = Goals_team_away,
Goal_diff_home = Goals_team_home - Goals_team_away,
Goal_diff_away = Goals_team_away - Goals_team_home)
missinggames <- map_df(1:nrow(missinggames), ~if(missinggames$Goals_team_home[.x] > missinggames$Goals_team_away[.x])
mutate(missinggames[.x,], points_team_home = 3, points_team_away = 0) else if
(missinggames$Goals_team_home[.x] == missinggames$Goals_team_away[.x])
mutate(missinggames[.x,], points_team_home = 1, points_team_away = 1) else
mutate(missinggames[.x,], points_team_home = 0, points_team_away = 3)
)
final_points <- map(unique(matchday30$club_name), ~ missinggames %>%
filter(club_name_home == .x ) %>%
select(points_team_home) %>%
sum()+ missinggames %>%
filter(club_name_away == .x ) %>%
select(points_team_away) %>%
sum()) %>%
unlist %>%
mutate(matchday30, points_new = .) %>%
mutate(points = points + points_new) %>% select(points)
final_goal_diff <- map(unique(matchday30$club_name), ~ missinggames %>%
filter(club_name_home == .x ) %>%
select(Goal_diff_home) %>%
sum()+ missinggames %>%
filter(club_name_away == .x ) %>%
select(Goal_diff_away) %>%
sum()) %>%
unlist %>%
mutate(matchday30, goal_diff_new = .) %>%
mutate(goal_diff = goal_diff + goal_diff_new ) %>%
select(goal_diff)
final_table <- matchday30 %>%
select(club_name) %>%
mutate(points = final_points$points,
goal_diff = final_goal_diff$goal_diff) %>%
arrange(desc(points), desc(goal_diff)) %>%
mutate(rank = 1:16)%>%
select(rank, everything())
all_final_tables <- bind_rows(all_final_tables,final_table)
average_table <- aggregate(
all_final_tables[1:(length(clubs)*(i-1)),-1],
by = list(all_final_tables$club_name[1:(length(clubs)*(i-1))]),
FUN = "mean"
)
average_table2 <- aggregate(
all_final_tables[,-1],
by = list(all_final_tables$club_name),
FUN = "mean"
)
conv_speed <- sum(abs(average_table$score-average_table2$score))
conv <- c(conv, conv_speed)
if(i %% 10 == 0){
message("convergence speed: ", round(conv_speed, 3), " run ", i, " out of ", N)
}
if(conv_speed < limit){
message("converged!")
break
}
}
if(conv_speed < limit){
conv_plot <- qplot(x=1:length(conv), y=conv, geom = "jitter",
main = paste0("converged to below ", limit,
" after ", length(conv), " runs"))
} else {
conv_plot <- qplot(x=1:length(conv), y=conv, geom = "jitter",
main = paste0("didn't converge below ", limit,
" after ", N, " runs"))
}
return(list(all_final_tables, conv_plot))
}
But I am getting the error telling unmatch bracket in the line 1,29,34,87 only after saving the file. As per my knowledge line number 29-34 might be the hook to the error.
