Depending on constructor
, we construct the object as follows:
"data.frame"
(default): Wrap the column definitions in a data.frame()
call. If some
columns are lists or data frames, we wrap the column definitions in tibble::tibble()
.
then use as.data.frame()
.
"read.table"
: We build the object using read.table()
if possible, or fall
back to data.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"
: Use list()
and treat the class as a regular attribute.
