pairsrp

Produces a matrix with scatterplot, regression line and a loess smooth in the upper right panel;
 correlation coefficient (Pearson, Spearman or Kendall) and the probability of Ho in the lower left panel

 hplot

Set of tools for reading, writing and transforming spatial and seasonal data, model selection and specific statistical tests for ecologists. It includes functions to interpolate regular positions of points between landmarks, to discretize polylines into regular point positions, link distant observations to points and convert a bounding box in a spatial object. It also provides miscellaneous functions for field ecologists such as spatial statistics and inference on diversity indexes, writing data.frame with Chinese characters.
