Adjust font size in rms:::plot.anova.rms

Question

I am using the rms package for logistic regression using the example titanic dataset, plot() on an anova object can produce a figure like the following

My question is how can I make the text in the plot smaller (column names, chisquare statistic, p-values), I checked the internal function rms:::plot.anova.rms and see no such arguments.

Answer 1

I don't have access to the titanic dataset, so here is a reproducible example using iris :

library(rms)

iris2 <- within(iris, Sepal.Length <- Sepal.Length > 5.5)
model <- Glm(DF2formula(iris2), data = iris2, family = binomial)
plot(anova(model))

The function rms:::plot.anova.rms contains an ellipsis for passing arguments on to plot . Therefore, even though it is not a named argument, you can pass cex to control the text size:

plot(anova(model), cex = 0.7)
