Due to size limit, I cannot form plots on rstudio.
Do I modify my code? It cannot form any plot. I get the same notification of size limit.
This the line of code:
avg_users <- edx %>%
left_join(avg_movie_rating, by='movieId') %>%
group_by(userId) %>%
filter(n() >= 100) %>%
summarize(b_u = mean(rating - mu - b_i))
avg_users %>% qplot(b_u, geom ="histogram", bins = 30, data = ., color = I("grey"))
