Good day,
Why do I get a debug message and a change in browser level when I inspect the
title variable ? For the comparison variable, it simply prints its value and
remains at level 1.
aFunction <- function(comparison = c("within", "classifier", "selection"),
title = if(comparison[1] == "within") "Internal" else
"Between")
{
browser()
require(ggplot2)
comparison <- match.arg(comparison)
ggplot(mtcars, aes(wt, mpg)) + geom_point() + ggtitle(title)
}
aFunction()
Browse[1]> title
debug at #4: [1] "Internal"
Browse[3]>
