SimIAV(sd = 0.015, range = sd * 
    2, nyears = 30, start = c(1982, 
    1), freq = 12)

`sd`	standard deviation of the annual mean values
`range`	`range` of the annual mean values
`nyears`	number of years
`start`	beginning of the time series (i.e. the time of the first observation). The default is c(1982, 1), i.e. January 1982 which is the usual `start` date to compute trends on long-term series of satellite observations of NDVI. See `ts` for further examples.
`freq`	The frequency of observations. The default is 12 for monthly observations. Use 24 for bi-monthly observations, 365 for daily observations or 1 for annual observations. See `ts` for further examples.
