Arguments

x

A vector of proportions.

digits

The number of digits to use. Defaults to 1. Can be set globally via: options(numformdigits = n) where n is the number of digits beyond the decimal point to include.

less.than.replace

logical. If TRUE values lower than lowest place value, specified by digits, will be replaced with a less than sign followed by the double representation of the place value specified by digits. For example, if digits = 0 then replacement will be "<1%" or if digits = 2 then replacement will be "<.01%".

s

A string to paste at the end of the output from f_num. Defaults to percent sign. This could be useful, for example, to turn a single percent sign into an escaped version for LaTeX output.

...

Other values passed to f_num.

Value

Returns a string of publication ready digits.

f_percent(c(30, 33.45, .1), digits = 0, less.than.replace = TRUE)
## Escaped for LaTeX:
f_percent(c(30, 33.45, .1), digits = 0, less.than.replace = TRUE, s = '\\%')
f_prop2percent(c(.30, 1, 1.01, .33, .222, .01, .0001, NA), digits = 0,
    less.than.replace = TRUE)
