Convert a numeric vector to a percent

Usage

make_percent(x, digits = 2, scale = 100)

Arguments

x: A numeric vector you want to convert to percentages
digits: How many decimals should the value be rounded to. Default is 2 which means it will show two decimal places, or the hundredth decimal.
scale: A scaling factor: x will be multiplied by scale before formatting. This is useful if the underlying data is very small or very large. Default is 100.

Examples

# here's the default scale of 100
x <- c(0.0163, 0.95, 0.0008, 0.002)
make_percent(x)
#> [1] "1.63%" "95%"   "0.08%" "0.2%" 

# if the values have already been multiplied by 100 and you don't need to
# transform them, then make the scale 1
x <- c(1.63, 95, 0.08, 0.2)
make_percent(x, scale = 1)
#> [1] "1.63%" "95%"   "0.08%" "0.2%" 

# And if we want to round to the closest whole number set the digits to 0
x <- c(0.0163, 0.95, 0.0008, 0.002)
make_percent(x, digits = 0)
#> [1] "2%"  "95%" "0%"  "0%"
