Build a quoted data.frame.

Source: R/cf.R

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.

qchar_frame(...)

Arguments

...

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

Value

character data.frame

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.

Examples


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

#>                      measure training validation
#> 1 minus binary cross entropy     loss   val_loss
#> 2                   accuracy      acc    val_acc
str(x)
