This function takes the information stored in a formatting list, and converts it to a data frame. The data frame format is useful for storage, editing, saving to a spreadsheet, etc. The data frame shows the name of the formats, their type, and the format expression. For user-defined formats, the data frame populates additional columns for the label and order.
# S3 method for fmt_lst
as.data.frame(x, row.names = NULL, optional = FALSE, ...)The formatting list to convert.
Row names for the returned data frame. Default is NULL.
TRUE or FALSE value indicating whether converting to syntactic variable names is desired. In the case of formats, the resulting data frame will always be returned with syntactic names, and this parameter is ignored.
Any follow-on parameters.
A data frame that contains the values stored in the formatting list.
