R Documentation

Log grid seq

Generates a log grid

seq.log(from = 1, to = 1, length.out = 50, add.zero = FALSE, shifting = 0, ...)

`from`	First value.
`to`	Final value.
`length.out`	Number of values to generate.
`add.zero`	If TRUE, append the value 0 on the smaller end of the result.
`shifting`	Shifting to apply to the log grid. Negative values produce greater bunching up near the minimum, with the reverse for positive values. NOTE: `shifting + from` and `shifting + to` must both be greater than zero.
`...`	Dummy variables for compatibility

A vector of length length.out, plus one if add.zero is TRUE.
