   If your example involves something like a fitted model object that 
takes a long time to compute, you can pre-compute the model fit and 
store the object in an inst/testdata directory, then use something like

fitted_model <- readRDS(system.file("testdata", "my_example.rds", 
package = "mypackage"))

to retrieve it
