rnd: Round and format

In gmonette/yscs: Collection of tools used in York University's Statistical Consulting Service

Description

Round to a given number of significant digits to show variability in a vector of numbers.

Usage

rnd(x, digits, ...)

## Default S3 method:
rnd(x, digits = 3, ..., verbose = 0)

Arguments

x	an object to be rounded and formatted
digits	significant digits for variation in x
...	passed on to format function

Details

Instead of rounding to a given number of significant digits, or rounding to a given significance, 'rnd' rounds so that the variability in a set of number is exhibited to a given number of digits. For example, 100.1233, 100.2345, 100.3456, rounded to 3 significant digits would be 100., 100., 100., but rounded to 3 significant digits for variability is 100.123, 100.234, 100.345.
