Interprets a character vector as names of logarithms

linear_scale.Rd

The values in x are possibly given in a logarithmic space. The parameter str_scale gives this logarithmic scale (provided in a language agnostic form), by a human. An empty string causes no transformations. Similarly, providing no scale at all causes no transformations.

Usage

linear_scale(x, str_scale = attr(x, "scale"))

Arguments

x

values

str_scale

character vector

Value

a copy of x, transformed in to linear space

Details

The words in str_scale name a logarithm, e.g. "log10". Currently understood scales:

  • log10

  • log2, ld

  • ln, log

Examples

if (FALSE) {
x <- c(1,2,3)
attr(x,"scale") <- c("log10","log2","log")
print(linear_scale(x))
}
