n

Integer number of random numbers to return.

fit

Data frame defining the emprical distribution (see details).

A numeric vector.

The distribution function is defined by fit, which must be a dataframe containing (at least) columns named: x: a regular sequence of values from which to draw; y: corresponding pdf values.

Examples

# NOT RUN {
data(BCItime)
tm <- 2*pi*subset(BCItime, species=="paca")$time
mod <- fitact(tm)
rn <- redf(1000, as.data.frame(mod@pdf))
# }
