Usage
timeSequence(from, to, by, length.out, k.by=1, align.by=FALSE,
extend=FALSE, week.align=NULL, holidays=timeDate(), exceptions,
additions, format, zone )Arguments
from
the starting value of the sequence: a timeDate object (or number or
character string representing one).
to
the ending value of the sequence: a timeDate object (or number or
character string representing one).
by
the spacing between successive values in the sequence. This can be
a timeSpan, timeRelative, or numeric value,
in which case k.by is ignored.
Alternatively, it can be one
of the following characte
length.out
the length of the sequence before additions and exceptions.
k.by
a non-zero integer giving the width of the interval between consecutive
values in the sequence in terms of the units given in by. Ignored if
by is not a character string.
align.by
a logical value. If TRUE, adjusts the sequence so that each element is on a whole number
of the by * k.by units. For example, if the units are 2 months, the sequence is
on only the first of January, March, May, and so on.
Ignor
extend
a logical value. If TRUE and align.by is also TRUE,
instead of making the entire sequence lie between from and to,
make it extend just past from and to
to the nex
week.align
if by is "weeks",
you can supply a character
string (or a number 0 to 6, with 0 being Sunday)
to specify a weekday to use. The character string must
be sufficient to make a unique case-insensitive match to the strings
in
holidays
the holidays for business day sequences (ignored if by is not
a character string).
exceptions
an event object giving time periods when sequence should not have any values.
These are applied after the sequence is created from from/to/by/length.out.
additions
additional times/dates to put in the sequence.
format
the time/date output format for printing.
zone
the time zone for the sequence.
