This new package aims to fit into the tidyverse and grammar of graphics suite to support and facilitate temporal-context data analysis and visualisation. A new class tbl_ts will be defined and provided for representing regular time series in a tidy data structure. Some common verbs from the dplyr package, such as filter, summarise, and mutate, will be inherited to transform temporal data more easily and intuitively. New calendar-based arrangements created using linear algebra tools will be developed to display temporal data in a format that captures people’s daily schedules. A new faceting system that attempts to reflect a nested structure will be experimented, which would provide a visualisation framework for hierarchical and grouped time series data.
