Formatting Extreme Values

Rtables Formatting Functions that handle extreme values.

Usage

h_get_format_threshold(digits = 2L)

h_format_threshold(x, digits = 2L)

format_extreme_values(digits = 2L)

format_extreme_values_ci(digits = 2L)

Arguments

digits

(integer)
number of decimal places to display.

x

(number)
value to format.

Details

For each input, apply a format to the specified number of digits. If the value is below a threshold, it returns "<0.01" e.g. if the number of digits is 2. If the value is above a threshold, it returns ">999.99" e.g. if the number of digits is 2. If it is zero, then returns "0.00".

Functions

• h_get_format_threshold(): Internal helper function to calculate the threshold and create formatted strings used in Formatting Functions. Returns a list with elements threshold and format_string.

• h_format_threshold(): Internal helper function to apply a threshold format to a value. Creates a formatted string to be used in Formatting Functions.

• format_extreme_values(): Create Formatting Function for a single extreme value.

• format_extreme_values_ci(): Create Formatting Function for extreme values part of a confidence interval. Values are formatted as e.g. "(xx.xx, xx.xx)" if if the number of digits is 2.

Examples

h_get_format_threshold(2L)
#> $threshold
#>    low   high 
#>   0.01 999.99 
#> 
#> $format_string
#>       low      high 
#>   "<0.01" ">999.99" 
#> 

h_format_threshold(0.001)
#> [1] "<0.01"
h_format_threshold(1000)
#> [1] ">999.99"

format_fun <- format_extreme_values(2L)
format_fun(x = 0.127)
#> [1] "0.13"
format_fun(x = Inf)
#> [1] ">999.99"
format_fun(x = 0)
#> [1] "0.00"
format_fun(x = 0.009)
#> [1] "<0.01"

format_fun <- format_extreme_values_ci(2L)
format_fun(x = c(0.127, Inf))
#> [1] "(0.13, >999.99)"
format_fun(x = c(0, 0.009))
#> [1] "(0.00, <0.01)"
