show0 {PBSmodelling}

Convert Numbers into Text with Specified Decimal Places

Description

Return a character representation of a number with added zeroes out to a specified number of decimal places.

Usage

show0(x, n, add2int=FALSE, round2n=FALSE)

Arguments

x

numeric data (scalar, vector, or matrix).

n

number of decimal places to show, including zeroes.

add2int

if TRUE, add zeroes to integers after the decimal.

round2n

if TRUE, round x first to n decimal places.

Value

A scalar/vector of strings representing numbers. Useful for labelling purposes.

Note

By default, this function does not round or truncate numbers. It simply adds zeroes if n is greater than the available digits in the decimal part of a number. The user can choose to round the numbers first by setting argument round2n = TRUE.
