It is just a number. The OP function works fine, the error was generated by wireframe because of the "partial" data passed to formula - OptionPrice is a matrix, not a column in the grid data.frame which only holds the scales. Anna, Replace call to wireframe in your function with wireframe(OptionPrice,main="3D Option", drape=T, col.regions=heat.colors(100), scales = list(arrows=F,x=list(at=1:length(t),labels=t),y=list(at=1:length(s),labels=s))) Then: plotbs(16) Note, the first value is always NaN but that's from your calculations - look at the OptionPrice matrix.
