How can I create a frequency table for a categorical variable?

Question

I'm new to R and am working with a dataset that involves the favourite colours of people collected in a survey.

I simply have a list of responses with colours being repeated, and so I want to make a frequency table I can work from (to create stacked bar plots, or pie charts).

I tried just using the 'table' function but I was unable to use the created table any further when it came to making plots.

Here is an example of the data: mostFav

1      Blue
2       Red
3       Red
4     Black
5      Blue
6     Black
7    Purple
8      Blue
9    Orange
10    White
11    Green
12    Green
13     Blue
14     Blue
15     Blue
16     Blue
17    Brown
18     Blue
19     Blue
20    Black

Answer 1

Depending on what you want to do, you can also try using ggplot without transforming the data into a table first.

mostFav <- data.frame("color" = c('Blue', 'Red', 'Red', 'Black', 'Blue', 'Black', 'Purple', 'Blue', 'Orange', 'White', 'Green', 'Green', 'Blue', 'Blue', 'Blue', 'Blue', 'Brown', 'Blue', 'Blue', 'Black'))

library(ggplot2)

ggplot(data = mostFav, aes(x = color)) +
  geom_bar()
