Print a Calendar Time Series

DESCRIPTION:

Formats and prints a calendar time series. This method is automatically called by print when given a time series of class cts.

USAGE:

print.cts(x, max.freq = 12, labels = NULL, abb = T, 
        quote = F, ...) 

REQUIRED ARGUMENTS:

x
a univariate or multivariate calendar time series (class "cts").

OPTIONAL ARGUMENTS:

max.freq
(univariate time series only): number compared with integer frequencies. If frequency(x) is less than or equal to max.freq, then the special printing format described in DETAILS is used. Default is 12
labels
a character vector of length frequency, If the special printing format is used, labelsare used as column labels for the output.
abb
logical flag: if TRUE, abbreviations of the month names are used as column lables when appropriate, if FALSE the month names are written out in full. Default is TRUE.
quote
logical flag: if TRUE, character strings are surrounded by quotes. Default is FALSE.

VALUE:

x, with the invisible flag set to prevent reprinting.

SIDE EFFECTS:

formats and prints x as a calendar time series.

DETAILS:

For univariate series with sufficiently small integer frequencies, the time series parameters, tspar(x), are used to ensure that either each line contains a full cycle or that a full cycle occupies an integral number of lines. Month abbreviations are used for column labels if frequency(x) is 12, and quarter abbreviations are used if frequency(x) is 4. Otherwise the observation number within the current cycle is used.

After each page of output, the column labels are printed again, so that there should always be a copy of the column labels on the screen at any time. To avoid multiple copies of the column labels, execute options(length=10000) to specify a very long page. A new format may be chosen at the end of each page.

The time parameters are written at the bottom.
