Removing (n=0) from sjplot::plot_xtab

Question

I'm trying to remove zero values from my visual using the plot_xtab function from the sjPlot package. I tried using drop.empty = FALSE , but that didn't seem to help.

I just don't like the way the "n=0 (0%)" looks. Does anyone know if this function still works or if there is an alternative?

Answer 1

You could remove the rows in the data from your plot with zeros. So if you save the plot as an object, you can extract the data. By conditionally removing the rows with zeros, these are gone in the plot. I don't have your data, so I created a reproducible example:

df <- data.frame(x = c(1,1,1,1,2,2,2,2,3,3,3,3,4,4,4,4),
                 y = c(1,0,1,2,3,2,1,0,4,3,1,2,0,2,1, 0))
library(sjPlot)
p <- plot_xtab(df$x, df$y)
p

# remove rows with prc = 0:
p$data <- p$data[p$data$prc != 0, ]
p

As you can see, the "n=0 (0%)" are gone
