Plot a frequency table in R

Question

I have a table with the results of a survey. I mean, I don't have the full survey data, only the frequency tables, Likert scale counts. Is it possible to graph this table in R?

The table looks like this: Question 1: (response is a factor)

response count
1        5
2        6
3        2
4        2
5        1

It's very easy to do it in Excel, but i can't in R. The only thing I could think of was to repeat the table values ​​based on the count, but there must be a simpler way...

Answer 1

A histogram-like chart from plot

plot(df,type = "h")

Answer 2

If we wanted to do this without having to install any package, use the base R methods with either a named vector in a single-line

barplot(setNames(df$count, df$response))

Or with the formula method for data.frame

barplot(count ~ response, df)

-output

data

df <- structure(list(response = 1:5, count = c(5L, 6L, 2L, 2L, 1L)),
  class = "data.frame", row.names = c(NA, 
 -5L))

Answer 3

Try this ggplot2 approach. You can set your response as x variable and count as y variable and use geom_col() in order to display bars. Here the code:

library(ggplot2)
#Plot
ggplot(df,aes(x=factor(response),y=count))+
  geom_col(color='black',fill='cyan3')+
  xlab('Response')

Output:

Some data used:

#Data
df <- structure(list(response = 1:5, count = c(5L, 6L, 2L, 2L, 1L)), class = "data.frame", row.names = c(NA, 
-5L))
