Description Usage Arguments Details Value Author(s) See Also Examples

A function to display a graph with the correlations between the reported environmental variables.

1	cor.data(abio, plot = TRUE, method = "pearson", rep = 1000)

`abio`	the rasters. Object of type RasterStack, generated by the function `stack`
`plot`	logic. Plots one of the cut rasters.
`method`	a character string indicating which correlation coefficient (or covariance) is to be computed: "pearson" (default), "kendall", or "spearman".
`rep`	numeric. Number of points generated to extract rater values and use in correlation. The default is 1000.

Graph indicating the correlations

Returns a table with the correlation values between the variables.
