Examples


# very simple KDE (adapted from example in Cairo())
openGraphCairo(type = "png", fileDirectory = tempdir())
plot(rnorm(4000), rnorm(4000), col = "#ff000018", pch = 19, cex = 2)
# save file 'norm.png' in directory specified in fileDirectory
saveGraphVisstat("norm", type = "png", fileDirectory = tempdir())
file.remove(file.path(tempdir(), "norm.png")) # remove file 'norm.png'
#> [1] TRUE
