Compute a classical semi-variogram for a single regular time series

1	vario(x, max.dist=length(x)/3, plotit=TRUE, vario.data=NULL)

`x`	a vector or an univariate time series
`max.dist`	the maximum distance to calculate. By default, it is the third of the number of observations
`plotit`	If `plotit=TRUE` then the graph of the semi-variogram is plotted
`vario.data`	data coming from a previous call to `vario()`. Call the function again with these data to plot the corresponding graph

A data frame containing distance and semi-variogram values
