Read the numbers off a summaryByVisit table

Converts a table produced by summaryByVisit() into a data frame with one row per variable, visit, group and (for categorical variables) level, holding the parsed numbers. This is the parser behind plotByVisit().

Usage

tidySummaryByVisit(tbl, stat_cont = NULL)

Arguments

tbl

A table returned by summaryByVisit() with as_flex_table = FALSE (the default TRUE returns a flextable, from which the numbers cannot be read back).

stat_cont

The statistic of continuous variables, as passed to summaryByVisit(). Default is NULL, which reads it from the table footnote; if the footnote is not recognised, plotByVisit() stops and asks for stat_cont rather than guess. A stat_cont that does not fit the printed cells (e.g. "mean_sd" for a median (range) table) is an error too.

Value

A data frame with columns variable (the label of the header row), var_type, visitgroup, visit, visit_id (position of the visit within the variable), group, level (NA for continuous variables), stat (the cell as printed), n (the number of non-missing observations shown in the table's N column), and the parsed numbers centre, lower, upper (continuous) and count (categorical).
