Plot methods for "timeDate"
objects.
## S4 method for signature 'timeDate' plot(x, y, ...) ## S4 method for signature 'timeDate' lines(x, y, ...) ## S4 method for signature 'timeDate' points(x, y, ...) axis.timeDate(side, x, at, format = NULL, labels = TRUE, ...) ## S3 method for class 'timeDate' pretty(x, n=5, min.n=n%/%3, shrink.sml=0.75, high.u.bias=1.5, u5.bias=0.5+1.5*high.u.bias, eps.correct=0, ...)
x, y, at |
an object of class |
side |
an integer specifying which side of the plot the axis is to be drawn on. The axis is placed as follows: 1=below, 2=left, 3=above and 4=right. |
format |
a POSIX format string, e.g. "%Y-%m-%d". |
labels |
either a logical value specifying whether annotations are to be made at the tickmarks, or a vector of character strings to be placed at the tickpoints. |
n |
an integer giving the desired number of intervals. |
min.n |
a nonnegative integer giving the minimal number of intervals. |
shrink.sml |
a positive numeric by a which a default scale is shrunk in the case when range(x) is very small. |
high.u.bias |
a non-negative numeric, typically > 1. Larger high.u.bias values favor larger units. |
u5.bias |
a non-negative numeric multiplier favoring factor 5 over 2. |
eps.correct |
an integer code, one of 0,1,2. If non-0, a correction is made at the boundaries. |
... |
arguments passed to other methods. |
returns a summary report of the details of a "timeDate"
object. This includes the starting and end date, the number of dates
the format and the financial center in use.
