If this helps, here is what I have currently mean.p<- .5 contrast<-1 amp<- contrast*mean.p freq<- 3 n<- 100 p<-amp*cos(2*pi*freq*(1:n)/n ) + mean.p plot(p) dens<-as.numeric(runif(1:n)<p) plot(p, type="l") points(dens, col="red")
I would like some dots having y-value=0.5 in the middle of the plot. These will reduce the error of approximation. Thanks for any help.
