Font size in likert plots (HH package)

Question

How can I control the size of labels and legend text?

This example is taken right of the HH documentation:

require(HH)
data(ProfChal)  ## ProfChal is a data.frame.
likert(Question ~ . , ProfChal[ProfChal$Subtable=="Employment sector",],
   main='Is your job professionally challenging?', ylab=NULL)

To be more specifically, I would like to increase the size of the five labels on the left side of the figure.

Answer 1

HH generates lattice plots, so lattice commands should work. To change the text size for the y-axis labels, add this line to your code: scales = list(y = list(cex = 1.2)), where cex in the multiplier to control the text size.

    library(HH)

    data(ProfChal)  ## ProfChal is a data.frame.

    likert(Question ~ . , ProfChal[ProfChal$Subtable=="Employment sector",],
       main='Is your job professionally challenging?', 
       ylab=NULL, 
       scales = list(y = list(cex = 1.2)))
