hi all, I have a plot to which i would like to add text labels. And i cant find a way...here is the code : enaD2<-idw(D2~1, loca=dva, newdata=grd) pts = list("sp.points", dva, pch = 20, cex=1.5, col = "darkred spplot(enaD2, "var1.pred",sp.layout=pts, main = "globina 60 cm", sub="D2",

...art attr_reader :items attr_reader :total_price def initialize @items = [] @total_price = 0.0 end def add_product(product) @items << LineItem.for_product(product) @total_price += product.price end end [CODE] What is the problem that it gives me that float error? Eeverything seems to be in order. -- Posted via http://www.ruby-forum.com/.
