These options will be used on objects of class 'data.frame'.
Usage
opts_data.frame(
constructor = c("data.frame", "read.table", "next", "list"),
...,
recycle = TRUE
)Details
Depending on constructor, we construct the object as follows:
"data.frame"(default): Wrap the column definitions in adata.frame()call. If some columns are lists or data frames, we wrap the column definitions intibble::tibble(). then useas.data.frame()."read.table": We build the object usingread.table()if possible, or fall back todata.frame()."next": Use the constructor for the next supported class. Call.class2()on the object to see in which order the methods will be tried."list": Uselist()and treat the class as a regular attribute.
