anyone wanna give this a shot.. try to figure out how to interpolate this better? http://stackoverflow.com/questions/...ver-volatility-surface-graph-in-r-programming
not sure how R interp works but doesnt it bring back a function that you can pass args to to get an interpolated value? so you could create your own points
good resource.... http://rseek.org/ another good way.. is to subscribe to anything that shows up with the Tag "R" in stackoverflow.. in the console.. RSiteSearch("key phrase")
