plot.multiFunData | R Documentation |
This function plots observations of multivariate functional data on their domain. The graphic
device is split in a number of subplots (specified by dim
) via mfrow
(par
) and the univariate elements are plotted using plot
.
## S3 method for class 'multiFunData'
plot(
x,
y,
obs = seq_len(nObs(x)),
dim = seq_len(length(x)),
par.plot = NULL,
main = names(x),
xlab = "argvals",
ylab = "",
log = "",
ylim = NULL,
...
)
## S4 method for signature 'multiFunData,missing'
plot(x, y, ...)
x |
An object of class |
y |
Missing. |
obs |
A vector of numerics giving the observations to plot. Defaults to
all observations in |
dim |
The dimensions to plot. Defaults to |
par.plot |
Graphic parameters to be passed to the plotting regions. The
option |
main |
A string vector, giving the title of the plot. Can have the same
length as |
xlab , ylab |
The titles for x- and y-axis. Defaults to |
log |
A character string, specifying the axis that is to be logarithmic.
Can be |
ylim |
Specifies the limits of the y-Axis. Can be either |
