I'm trying to make a histogram in [R], and the normal curve that describes the histogram as follows:
w<-rnorm(1000) hist(w,col="red",freq=F,xlim=c(-5,5)) curve(dnorm(w),-5,5,add=T,col="blue")
But when I try to plot the normal curve by curve function shows me the following error:
Error en curve(dnorm(w), -5, 5, add = T, col = "blue") : 'expr' must be a function, or a call or an expression containing 'x'
What am I doing wrong?
