Time Series Plotting Functions
integerspecifying 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.
numericvector giving the points at which tick-marks are to be drawn. If
NULL, tickmark locations are computed.
characterstring specifying the prefix. It should be one of "
Ma" or "
TRUE, a good guess for an appropriate format is made.
## Create a time-series of 300 observations ## Sampled every two years starting from 2000 BP X <- series( object = rnorm(300), time = seq(2000, by = -2, length.out = 300), calendar = BP() ) ## Axis plot(X, axes = FALSE, calendar = BP()) # Remove axes year_axis(side = 1) # Same calendar as last plot year_axis(side = 3, calendar = CE()) # Specific calendar mtext(format(CE()), side = 3, line = 3) ## Grid plot(X, panel.first = graphics::grid())
