prettylog: Pretty Breakpoints on Log Scale

In JVAdams/LW1949: An Automated Approach to Evaluating Dose-Effect Experiments Following Litchfield and Wilcoxon (1949)

Description

Compute a sequence of "round" values which cover the range of x on the log scale.

Usage

prettylog(x, lead = c(1, 5), extra = 5)

Arguments

x	A numeric vector.
lead	An integer vector giving the desired lead digits of pretty values on the log scale, default c(1, 5).
extra	An integer scalar giving the desired number of additional non-log scale values to include, default 5.

Value

A numeric vector of pretty values covering the range of x on the log scale.

Examples

vals <- rlnorm(100, 6)
summary(vals)
prettylog(vals, 1, 0)
prettylog(vals, 1)
prettylog(vals, c(1, 2, 5))
