[R] dnorm

["Sibylle Stöckli"]

Dear R-users

Idea:
Plot a dnorm line using specific mean/sd to complete a histogram (skewed). xs:range of y-values, ys: dnorm function

Problem:
I expected to multiply the ys function with the sample size (n=250-300). I was wondering about a factor between 12'000 and 30'000 to match the size of the dnorm line with the specific histogram.

Thanks
Sibylle

hist(Biotree[Ld,]$Height2008, main="Larix decidua", ylim=c(0,50), xlab="Tree Height 2008 (cm)",col="aquamarine", font.main=3, cex.axis=0.8)
xs<-0:650
ys<-dnorm(xs, mean=397.8, sd=97.6)
lines(xs,ys*12000)
