fread_folder is broken w.r.t. recent data.table

[MichaelChirico]

Hello, in our efforts to prepare data.table for an update on CRAN (-> v1.11.0), we noticed that recent changes will break your package:

install.packages('data.table', type = 'source', repos = 'http://Rdatatable.github.io/data.table')
pkg = 'easycsv'
install.packages(pkg, dependencies = TRUE)

tools::testInstalledPackage(pkg, outDir = "~/Desktop/dt_revdep")

library(pkg, character.only = TRUE)
fn = 'fread_folder'
example(fn, character.only = TRUE)

Error: isTrueFalse(showProgress) is not TRUE

This is because the default argument of showProgress has changed to be equivalent to the output of interactive(), and the default value of getOption('datatable.showprogress') has been deleted.

Please follow Rdatatable/data.table#2785 and feel free to provide input there if you have strong opinions about how to proceed.

Note that this issue also effects your SIRItoGTFS package; I'll file an official issue there once the aforementioned pull request is resolved, if needed.

@MichaelChirico
just uploaded a fix to the repository here and tagged as a version 1.0.8.
if all tests come back alright and I won't get any more issues in the following week I'll send the new version to CRAN.
won't close this issue yet.
as far a SIRItoGTFS is concerned it'll receive a fix when I have time to debug the entire library.
