How to create a joint frequency table?

[jesussmariscal]

Hello,

I have to create a joint frequency table with this information:

And I tried to use the command x=c(rep(x,ni)...) as I use to do with the normal frequency tables But this is different and i have no clue how to do it.

Knows someone how to do it?

Thank you.

Welcome. Here is an example with the penguins dataset from the palmerpenguins package.

library(palmerpenguins)
table(penguins[, c("species", "island")])

           island
species     Biscoe Dream Torgersen
  Adelie        44    56        52
  Chinstrap      0    68         0
  Gentoo       124     0         0

The point is that I only have that table. I mean, I can’t open it from a library

Can you provide a reproducible example?

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
