Format numbers using smart scientific notation

Formats numeric values by applying scientific notation only when values fall below a specified threshold, and fixed notation otherwise. This is useful for variables with a wide range of small values where some require scientific notation but others do not, such as p-values. The defaults are designed for p-values.

Usage

smart_fmt_sci(x, threshold = 1e-04, sci_digits = 2, num_digits = 4)

Arguments

x: numeric() A numeric vector to format.
threshold: numeric(1) Values with absolute value below this threshold are formatted in scientific notation. Defaults to 0.0001.
sci_digits: integer(1) Number of significant digits for values formatted in scientific notation. Defaults to 2.
num_digits: integer(1) Number of significant digits for values formatted in fixed notation. Defaults to 4.

Value

character() A character vector of formatted numbers.

Details

Uses formatC() internally with format = "e" for scientific notation and format = "fg" for fixed notation. The "fg" format uses significant digits rather than decimal places, giving consistent precision across values of different magnitudes.

Examples

if (FALSE) { # \dontrun{
x <- c(0.5, 0.0000001, 0.00032, 0.000000000123)

smart_fmt_sci(x)
#> [1] "0.5"      "1.00e-07" "0.00032"  "1.23e-10"

smart_fmt_sci(x, threshold = 0.001, sci_digits = 3, num_digits = 6)
#> [1] "0.5"       "1.000e-07" "3.200e-04" "1.230e-10"
} # }
