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

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.

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.
