The R package 'ardl.nardl' has some examples that take more than 5

How can this be achieved?
- you can lower the amount of data in the example
- you can use a faster method than your default method
- you can wrap the example in a dontrun tag so it will not run during
checking
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
The "sos" package includes a function "CRAN", which is used for that
purpose. The examples section in "findfn.Rd" includes the following:
# Skip these tests on CRAN,
# because they take more than 5 seconds
if(!CRAN()){
...
}
I know that some on this list do not like this construct, but it has
helped me manage this problem for several years. NOTE: This CRAN
function is NOT maintained by anyone on CRAN, so it is NOT guaranteed to
work. However, the "sos" package is currently on CRAN, and I have not
seen an email asking me to avoid it ;-)

Hope this helps.
