scagnostics {scagnostics} | R Documentation |
Scagnostics summarise potentially interesting patterns in 2d scatterplot
scagnostics(x, ...)
x |
object to calculate scagnostics on: a vector, a matrix or a data.frame |

Current scagnostics are:
These are described in more detail in: Graph-Theoretic Scagnostics, Leland Wilkinson, Anushka Anand, Robert Grossman. http://www.ncdm.uic.edu/publications/files/proc-094.pdf
You can call the function with two 1d vectors to get a single vector of scagnostics, or with a 2d structure (matrix or data frame) to get scagnostics for every combination of the variables.
