Utility functions for safe logarithm transformations and min-max scaling.
safe_log10 and safe_log2 return NA for non-positive values.
scale_0_100 (alias rescale_minmax) scales values to 0-100 range.
Usage
safe_log10(x)
safe_log2(x)
scale_0_100(x)
rescale_minmax(x)
Arguments
- x
Numeric vector
Value
Numeric vector with transformed values
Examples
safe_log10(c(1, 10, 100, 0, -5, NA))
#> Warning: NaNs produced
#> [1] 0 1 2 NA NA NA
safe_log2(c(1, 2, 4, 0, -5, NA))
#> Warning: NaNs produced
#> [1] 0 1 2 NA NA NA
scale_0_100(c(10, 20, 30, 40, 50))
#> [1] 0 25 50 75 100
