Build a data.frame from the user's description.

Source: R/cf.R

A convenient way to build a data.frame in legible transposed form. Position of first "|" (or other infix operator) determines number of columns (all other infix operators are aliases for ","). Names are de-referenced.

build_frame(..., cf_eval_environment = parent.frame())

Arguments

...

cell names, first infix operator denotes end of header row of column names.
cf_eval_environment

environment to evaluate names in.

Value

character data.frame
