How not to get the data squeezed with boxplot? - r

Question

This is an assignment that I have to boxplot() but I somehow got the data squeezed. I'm new to R :(
I guess the problem is because the x axis labels are too long and not placed vertically, so I've tried and failed (based on this Inserting labels in box plot in R on a 45 degree angle?)
examples <- read.csv("mov.development.csv", sep="\t")
library(dplyr)
movies_rated_67_times <- examples %>%
group_by(movie) %>%
summarize(count=n(), avg_rating=mean(rating))%>%
filter(count == 67)
boxplot_data <- examples %>%
filter(movie %in% movies_rated_67_times$movie) %>%
select(title, rating)
boxplot(rating~title,
data=boxplot_data,
xlab="Title",
ylab="Rating",
xaxt = "n"
)
text(seq_along(boxplot_data$title), par("usr")[3] - 0.5, labels = names(boxplot_data$title), srt = 90, adj = 1, xpd = TRUE);
I want to have a plot like this
But I got this
But with a different type of labels that are not too long, normal code would work
Normal code:
examples <- read.csv("mov.development.csv", sep="\t")
library(dplyr)
movies_rated_67_times <- examples %>%
group_by(movie) %>%
summarize(count=n(), avg_rating=mean(rating))%>%
filter(count == 67)
boxplot_data <- examples %>%
filter(movie %in% movies_rated_67_times$movie) %>%
select(movie, rating)
boxplot(rating~movie,
data=boxplot_data,
xlab="Title",
ylab="Rating"
)

Transforming your title column from factor to character seems to fix it. Additionally I would insert line breaks into some of the movies names and reduce the text size so it fit's into the plot
boxplot_data <- examples %>%
filter(movie %in% movies_rated_67_times$movie) %>%
mutate(title = as.character(title)) %>%
select(title, rating)
boxplot_data[boxplot_data$title == "Adventures of Robin Hood, The (1938)",]$title <- "Adventures of Robin Hood,\nThe (1938)"
boxplot_data[boxplot_data$title == "Wallace & Gromit: The Best of Aardman Animation (1996)",]$title <- " Wallace & Gromit: The Best of\nAardman Animation (1996)"
boxplot_data[boxplot_data$title == "Bridges of Madison County, The (1995)",]$title <- "Bridges of Madison County,\nThe (1995)"
par(cex.axis = 0.7)
boxplot(rating~title,
data=boxplot_data,
xlab="Title",
ylab="Rating")
