| data | (ANY) the variable data. Can be any data object for which is.rectangular is TRUE, such as a data.frame, matrix, or atomic vector. | 
| positions. | (positions) the x values for the variables. Must be of type positionsCalendar. If not given, then the positions are computed using the timeSeq function with the from, by, k.by, align, and week.align arguments. | 
| units. | (character) the units for the data. | 
| from | the starting value of the sequence. A timeDate object (or number or character string representing one). | 
| by | the spacing between successive values in the sequence. Can be
    a timeSpan, timeRelative, or numeric value,
    in which case k.by is ignored. Alternatively, it can be one of the following character strings: 
 | 
| 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 only on the first of January, March, and so on. Ignored if by is not a character string. | 
| 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 timeDateOptions("time.day.name").)
