Can't access to data sets using `::`

[jbkunst]

Hi,

Thanks for this package and all the work put in tmwr!

I noted I can't access a data set using ::. There is a particular reason why datasets cannot be accessed using this way like other data packages?

library(modeldata)

modeldata::ames
#> Error: 'ames' is not an exported object from 'namespace:modeldata'
modeldata::credit_data
#> Error: 'credit_data' is not an exported object from 'namespace:modeldata'

Thanks so much in advance. Kinkd regrads,

I think this is because we have:

@topepo is there a reason why this package has LazyData: false?

If I just change the package to LazyData: true then I see this:

❯ checking LazyData ... WARNING
    LazyData DB of 5.2 MB without LazyDataCompression set
    See §1.1.6 of 'Writing R Extensions'

I think the datasets would need to be resaved with compression, maybe with tools::resaveRdaFiles().

I have a feeling we should be using LazyData: true. https://github.com/tidymodels/modeldata/issues/4

[topepo]

TBH I've never seen any code that uses package::data and I believe the proper idiom to use is data().

If someone wants to make a PR with LazyData: true, go ahead.
