logScale {ifultools} | R Documentation |
Creates a vector whose values are base-2 logarithmically spaced.
logScale(scale.min, scale.max, scale.ratio=2, scale.res=NULL, coerce=NULL)
scale.min |
an integer denoting the minimum scale. |
scale.max |
an integer denoting the maximum scale. |
coerce |
the coercion function to use on the resulting scale vector. Default: NULL (no coercion). |
scale.ratio |
a numeric value representing the ratio of the next scale over the current scale, i.e., the ratio of successive scales. Default: 2. |
scale.res |
the numeric value denoting scale resolution. This input serves
as an alternative to the scale.ratio input, and is related via
scale.ratio <- 1 / scale.res + 1 or conversely scale.res <- 1/(scale.ratio - 1) .
Default: NULL (scale.ratio is used instead). |
a numeric vector containing the scales.
logScale(scale.min = 1, scale.max=34, scale.ratio=4)
