seqMpfr

"mpfr" Sequence Generation

Description

Generate ‘regular’, i.e., arithmetic sequences. This is in lieu of methods for seq (dispatching on all three of from, to, and by.

Usage

seqMpfr(from = 1, to = 1, by = ((to - from)/(length.out - 1)),
        length.out = NULL, along.with = NULL, ...)

Arguments

`from, to`	the starting and (maximal) end value (numeric or `"mpfr"`) of the sequence.
`by`	number (numeric or `"mpfr"`): increment of the sequence.
`length.out`	desired length of the sequence. A non-negative number, which will be rounded up if fractional.
`along.with`	take the length from the length of this argument.
`...`	arguments passed to or from methods.

Details

see seq (default method in package base), whose semantic we want to replicate (almost).

Value

a ‘vector’ of class "mpfr", when one of the first three arguments was.
