\title{Correlogram}
\usage{
correlogram(x, v, dist = 5000, ns = 99, ...)
}
\arguments{
\item{x}{A sf POINT object}

\item{v}{Test variable in x}

\item{dist}{Distance of correlation lags, if latlong=TRUE units are
great circle in kilometers}

\item{ns}{Number of simulations to derive simulation envelope}

\item{...}{Arguments passed to cor ('pearson', 'kendall' or 'spearman')}
}
\value{
Plot of correlogram and a list object containing:
\itemize{
\item autocorrelation is a data.frame object with the following components
\item autocorrelation - Autocorrelation value for each distance lag
\item dist - Value of distance lag
\item lci - Lower confidence interval (p=0.025)
\item uci - Upper confidence interval (p=0.975)
\item CorrPlot recordedplot object to recall plot
}
}
\description{
Calculates and plots a correlogram
