Round the numeric columns of a data frame

The validation scripts call this as they write their summaries. Simulation output is quoted to three or four significant figures, so storing fifteen adds size and no information.

Usage

round_sig(x, digits = 6)

Arguments

x

A data frame.

digits

Significant figures, or NULL to return x unchanged, as files that a tolerance is asserted against need.

Value

x with its numeric columns rounded with signif().
