How to change the axis title font size of a `trellis` object?

I have a trellis object generated by a 3rd-party package. With that being said, I cannot change the attributes by re-creating another trellis object. I have to change its attributes after it has been created.

I have figured out which attributes control the axes' label font sizes, they are: my_trellis$x.scales$cex[1] and my_trellis$y.scales$cex[1]

But what about the axes' title font sizes? It took me some searches and still could not figure it out...

Thanks!

You can change trellis object of lattice package by using trellis.par.get and trellis.par.set function as below:

library(lattice)
# simulation
data("quakes")
Depth <- equal.count(quakes$depth, number=8, overlap=.1)
trellis <- xyplot(lat ~ long | Depth, data = quakes, main = "Large Font Title")


# change title font size
mt = trellis.par.get("par.main.text")
mt$cex = 2
trellis.par.set("par.main.text",mt)
trellis
class(trellis)

Output: library
