seqlog: Log-scale equidistant sequences

In NMcalc: Basic Calculations for PK/PD Modeling

Log-scale equidistant sequences

Description

Useful for generating sequences to be plotted on log scale. This is really simple - seq is run on from and to after log transformation, then the exponential is reported.

Usage

seqlog(from, to, length.out)

Arguments

from	start of sequence
to	end of sequence
length.out	length of sequence

Value

A numeric vector.

Examples

df <- data.frame(x=seqlog(1,100,100))
df <- transform(df, y=x/(10+x))
## Not run: 
library(ggplot2)
## the points are equidistant on the log x scale
ggplot(df,aes(x,y))+geom_point()+scale_x_log10()

## End(Not run)
