Plot Method for cardiFit Objects
Description
This function is a top-level function to visualize cardinal date objects
fitted with fitweibull4
and fitweibull6
.
Usage
## S3 method for class 'cardiFit'
plot(x, y = NULL, xmin = 0, xmax = 365, quantile = 0.05, symmetric = FALSE, ...)
Arguments
x
object of class cardiFit
resulting from a call to
fitweibull6
or fitweibull4
,
y
not used, for compatibility with plot only,
xmin
left boundary (in day of year) of the integral under the curve,
xmax
right boundary (in day of year) of the integral under the curve,
quantile
two-sided quantile (percentage of integral)
which defines beginning and end of the peak,
symmetric
if (TRUE
), quantiles are calculated for the whole area
under the curve, otherwise for each of the branches separately,
...
other arguments passed to plot.default
.

Examples
## create some test data
set.seed(123)
x <- seq(0, 360, length = 20)
y <- abs(rnorm(20, mean = 1, sd = 0.1))
y[5:10] <- c(2, 4, 7, 3, 4, 2)
## fit Weibull function with 6 free parameters
res <- fitweibull6(x, y)
## see the results
plot(res)
