Format Numbers for Printing

2 Decimal places, otherwise scientific notation

Usage

ddSci(x, decimal_places = 2, hi = 1e+06, as_numeric = FALSE)

Arguments

x

Vector of numbers

decimal_places

Integer: Return this many decimal places.

hi

Float: Threshold at or above which scientific notation is used.

as_numeric

Logical: If TRUE, convert to numeric before returning. This will not force all numbers to print 2 decimal places. For example: 1.2035 becomes "1.20" if as_numeric = FALSE, but 1.2 otherwise This can be helpful if you want to be able to use the output as numbers / not just for printing.

Value

Formatted number

Details

Numbers will be formatted to 2 decimal places, unless this results in 0.00 (e.g. if input was .0032), in which case they will be converted to scientific notation with 2 significant figures. ddSci will return 0.00 if the input is exactly zero. This function can be used to format numbers in plots, on the console, in logs, etc.
