example of geom_contour() with function argument
library(mvtnorm) # you were misusing "require"... only use require if
you plan to
library(ggplot2) # test the return value and fail gracefully when the
package is missing
set.seed( 1234 )
xx <- data.frame( rmvt( 100, df = c( 13, 13 ) ) )
xx2 <- expand.grid( X1 = seq( -5, 5, 0.1 ) # all combinations... could
be used to fill a matrix
, X2 = seq( -5, 5, 0.1 )

xx <- data.frame(rmvt(100, df = c(13, 13)))
v <- ggplot(data = xx,
