\title{Adds the \code{CPPALLY_CHECK_DATA_FRAMES} flag to Makevars}
\usage{
use_check_data_frames()
}
\value{
Invisibly adds the \code{CPPALLY_CHECK_DATA_FRAMES} flag to Makevars.
}
\description{
Adds a flag to Makevars which enables stricter validation on data frames
at the point of \code{r_df} construction. This ensures that column lengths are
always valid, avoiding potential R crashes downstream.

The default behaviour is NOT to validate column lengths, enabling faster
\code{r_df} creating from \code{SEXP}.
