In dewittpe/qwraps2: Quick Wraps 2

The object returned by summary_table is a character matrix with the additional S3 class qwraps2_summary_table. The rowgroup names Value1 and Group are not part of the character matrix explicitly, they are part attributes. The print method for the qwraps2_summary_table object builds the table as need for the appropriate markup language, LaTeX or markdown.

Two edits the the example posted to get the table you are looking for:

1. Add options(qwraps2_markup = "markdown") to your script. The default mark up language is LaTeX, setting this option changes the default to markdown.

2. Do not wrap summary_table inside of knitr::kable: this prevents the needed print method from being called.

options(qwraps2_markup = "markdown")
