tbrf 0.1.7

New features

• incorporate stat_stepribbon() from the ggalt package. This adds a dependency on ggplot, but it is a super useful stat for this type of data.
• adds the Entero example dataset to facilitate examples of analysis using lognormal data.
• new na.pad argument for all tbr_ rolling functions that will pad the results with NA values when the window length is less then argument n.

Bug fixes

• Remove vignette dependency, and DESCRIPTION suggests on ggalt package (#29).

Minor changes

• use usethis_import_from() to document imports under the tbrf-package.R.
• updated vignettes and examples with new example data.
