boxplot across multiple columns in R

Question

I'm new to R and having next to nothing experience with it I'm struggling with what may be a pretty easy problem. I have a dataset of acceptability judgments provided by a group of 30 participants on 7 different verbs. I need to plot the verbs on the x-axis and the scores on the y-axis, so every single verb must have 30 data points.

I've tried to change a sample code which seemed to be close to what I was intending to do:

library(ggplot2)
data <- data.frame(y=abs(rnorm(16)), x=rep(c(0,100,200,300,400,500,600,700), each=2)) 
ggplot(data, aes(x, y, group=x)) + 
geom_boxplot(fill="green") +
xlab("x-axis") +
ylab("y-axis") +
ggtitle("Continuous Box plot ")

I obviously changed the random dataset part inserting my own data:

data_frame<-data.frame(
arrivare=9,8,9,9,9,9,9,9,9,9,9,9,7,9,9,9,9,9,9,9,9,9,9,9,5,9,9,9,9,8,9,
tornare=9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,8,8,
cambiare=9,8,9,9,9,9,9,8,9,9,9,9,9,8,9,7,9,9,9,9,9,9,9,9,9,9,9,9,9,9,8,
continuare=8,8,6,9,8,5,2,7,7,9,1,2,7,8,1,9,9,9,8,9,6,9,1,6,9,1,8,9,8,9,
vivere=9,3,7,1,9,9,2,8,5,6,3,2,9,6,9,2,9,9,5,1,9,1,9,1,1,1,1,9,9,8,7,
abitare=1,1,1,1,1,7,1,1,2,7,1,2,3,1,1,1,1,1,5,1,1,1,1,1,1,1,1,1,1,1,3,
suonare=7,1,8,1,7,7,1,9,8,8,1,1,9,6,1,9,1,9,3,3,2,9,1,7,5,1,9,9,8,9)

But I definitely got this part wrong:

Do you have any suggestions on how to solve this issue?

Thank you!

Answer 1

I guess you can simply run boxplot

boxplot(df)

or fancier with ggplot

df %>%
  pivot_longer(everything()) %>%
  ggplot(aes(x = factor(name, levels = unique(name)), y = value)) +
  geom_boxplot(fill = "green") +
  xlab("x-axis") +
  ylab("y-axis") +
  ggtitle("Continuous Box plot ")

data

df <- data.frame(
  arrivare = c(9, 8, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 7, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 5, 9, 9, 9, 9, 8, 9),
  tornare = c(9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 8, 8),
  cambiare = c(9, 8, 9, 9, 9, 9, 9, 8, 9, 9, 9, 9, 9, 8, 9, 7, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 8),
  continuare = c(8, 8, 6, 9, 8, 5, 2, 7, 7, 9, 1, 2, 7, 8, 1, 9, 9, 9, 8, 9, 6, 9, 1, 6, 9, 1, 8, 9, 8, 9, 9),
  vivere = c(9, 3, 7, 1, 9, 9, 2, 8, 5, 6, 3, 2, 9, 6, 9, 2, 9, 9, 5, 1, 9, 1, 9, 1, 1, 1, 1, 9, 9, 8, 7),
  abitare = c(1, 1, 1, 1, 1, 7, 1, 1, 2, 7, 1, 2, 3, 1, 1, 1, 1, 1, 5, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 3),
  suonare = c(7, 1, 8, 1, 7, 7, 1, 9, 8, 8, 1, 1, 9, 6, 1, 9, 1, 9, 3, 3, 2, 9, 1, 7, 5, 1, 9, 9, 8, 9, 9)
