Hi,
sadly it does not work either, because my index (x axis) is an atomic
vector.
Error Message: $ operator is invalid for atomic vectors
I think I have to stick to displaying the confidence intervals with
straight lines (ablines) , instead of a shaded area (polygon)
Thank you so much for your he
Hang on, maybe you mean something like this:
erupt_dens<-density(faithful$eruptions)
plot(erupt_dens,ylim=c(0,0.65))
dispersion(erupt_dens$x,erupt_dens$y,ulim=erupt_dens$y/5,
type="l",fill="lightgray",interval=TRUE)
lines(erupt_dens)

In order to display a polygon, you need x/y pairs for each point. If
you just want a rectangle, you only need four x/y pairs, e.g.:
plot(0,xlim=x(2.44,2.57),ylim=c(0,1),type="n")
polygon(c(2.44,2.57,2.57,2.44),c(0,0,1,1),col="lightgray")
Now if you have a series of x values and want to display a
Thank you,
this seems to work, but it is not exactly what I need (it indeed looks
great, but a bit beyond my understanding)
I just need a shaded area between 2.44 to 2.57 along the x-axis - a
polygon inserted into my density plot (and not a confidence line along a
scatter plot like your suggeste
Hi Elysa,
I think you are going a bit off course in your example. Try this and
see if it is close to what you want:
data<-rnorm(100)+runif(100,0,15)
smu_data<-supsmu(1:100,data)
rollfun<-function(x,window=10,FUN=sd) {
xlen<-length(x)
xout<-NA
forward<-window%/%2
backward<-window-forward
for(i
Hi, thank you!
I've constructed the upper and lower bounds with
a <- 2.505766
s <- 0.7789832
n <- 607
error <- qnorm(0.975)*s/sqrt(n)
left <- a-error
right <- a+error
left
right
Now, I have the numbers I need, but I have no idea how to plot them. I was
thinking of using a polygon, but som
