I wanna make a plot with contour, but i got this warning message \
data34=bkde2D(data[,3:4],bandwidth = sapply(data[,3:4],dpik))
Warning message:
In bkde2D(data[, 3:4], bandwidth = sapply(data[, 3:4], dpik)) :
Binning grid too coarse for current (small) bandwidth: consider increasing 'gridsize'
What should i do?
