Generate a sequence over the range of a vector

Description

Stolen from here

Usage

seq_range(x, n, by, trim = NULL, expand = NULL, pretty = FALSE)

Arguments

x	A numeric vector
n, by	Specify the output sequence either by supplying the length of the sequence with n, or the spacing between value with by. Specifying both is an error. I recommend that you name these arguments in order to make it clear to the reader.
trim	Optionally, trim values off the tails. trim / 2 * length(x) values are removed from each tail.
expand	Optionally, expand the range by expand * (1 + range(x) (computed after trimming).
pretty	If TRUE, will generate a pretty sequence. If n is supplied, this will use pretty() instead of seq(). If by is supplied, it will round the first value to a multiple of by.

Examples

x <- rcauchy(100)
seq_range(x, n = 10)
seq_range(x, n = 10, trim = 0.1)
seq_range(x, by = 1, trim = 0.1)

# Make pretty sequences
y <- runif (100)
seq_range(y, n = 10)
seq_range(y, n = 10, pretty = TRUE)
seq_range(y, n = 10, expand = 0.5, pretty = TRUE)

seq_range(y, by = 0.1)
seq_range(y, by = 0.1, pretty = TRUE)
