qchar_frame: Build a quoted data.frame.

In WinVector/wrapr: Wrap R Tools for Debugging and Parametric Programming

Build a quoted data.frame.

Description

A convenient way to build a character 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 treated as character types.

Usage

qchar_frame(...)

Arguments

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

Details

qchar_frame() uses bquote() .() quasiquotation escaping notation. Because of this using dot as a name in some places may fail if the dot looks like a function call.

Value

character data.frame

Examples

loss_name <- "loss"
x <- qchar_frame(
   measure,                      training,     validation |
   "minus binary cross entropy", .(loss_name), val_loss   |
   accuracy,                     acc,          val_acc    )
print(x)
str(x)
cat(draw_frame(x))

qchar_frame(
  x |
