SummaryTOTbyVar

This is a function that reports the number of students and a summary of time
on task aggregated by a specific variable.

Enables users to handle the dataset cleaning for conducting
specific analyses with the log files from two international educational
assessments: the Programme for International Student Assessment (PISA,
<https://www.oecd.org/pisa/>) and the Programme for the International
Assessment of Adult Competencies (PIAAC,
<https://www.oecd.org/skills/piaac/>). An illustration of the analyses can be
found on the LOGAN Shiny app (<https://loganpackage.shinyapps.io/shiny/>) on
your browser.
