Hello, I am working with two datasets with ~5,200 observations. Apparently, neither the correlog function (ncf package) nor the mantel function (ecodist package) can handle these datasets. Does anyone have any experience about the maximum number of observations these functions can handle? I am considering partitioning them into smaller subsets. This would not be an ideal solution as it changes the sampling space and its spatial dependence, so other suggestions for being able to create cross-correlograms are most welcome.... I am relatively new at doing this type of analysis in R. Thanks. Regards, Will.
