将一列的框 plot 与另一列的值显示为 x 轴

Question

I have data that looks as follows

"","Speaker","Total"
"1","David",19
"2","Grimes",29

I am looking to create a box plot in R as follows

I am able to create a box plot as follows

df = read.csv('C:\\abovefile.csv')
barplot(df$Total, main="Total v/s Speaker",xlab="Speaker name")

However, I wasn't able to figure out how to show the name of the speaker at the bottom of each bar. How can I do this in R?

My graph currently looks like this

Answer 1

Use the names argument in barplot:

df <- tibble(
    x = c("1","2"),
    Speaker = c("David", "Grimes"),
    Total = c(19,29)
)

barplot(df$Total, main="Total v/s Speaker",xlab="Speaker name",
        names = df$Speaker)

Answer 2

You can try this:

library(ggplot2)
#Plot
ggplot(data,aes(x=Speaker,y=Total))+
  geom_bar(stat = 'identity',color='black',fill='blue')
