search for: scove

...matplot(n,cbind(coves,es,t),type ='l', col=c("red","blue","black"),xlab='n',ylab='power') I want power curves to be smooth (avoid sawtooth curve), I try the follows, ##Spline library(modreg) st<- smooth.spline(t) ses<- smooth.spline(es) scoves<- smooth.spline(coves) plot(scoves,col='red', type='l') lines(ses, col='blue',type='l') lines(st,col='black',type='l') The shapes are what I want, but I want x-axis consistent to the correspond to n. Does anyone know the solution? Thanks, Kat...
