I have dataframe in R that contains the the true value of a parameter, and its corresponding lower and upper values for confidence interval. The codes are as follows:
n = 100*c(1:10)
lambda = 0.1
Ilambda = #formula excluded
varI = Ilambda^(-1/2)/sqrt(n)
upper = lambda+1.96*varI
lower = lambda-1.96*varI
index = rep(lambda,length(n))
data = data.frame(n,lower,upper,index)
data = as_tibble(data)
ggplot(data)+
geom_line(aes(n, index),cex = 1)+
geom_ribbon(aes(ymin = lower, ymax = upper), fill = "grey")
Attached figure is how I pictured it with some shading towards the line y = 0.1, like an usual shading for confidence interval. I learned that geom_ribbon can do the shading for confidence interval but there is an error message which is
Error: geom_ribbon requires the following missing aesthetics: x or y, xmin and xmax
I am open to other suggestions.
Also, the ribbon will hide the line - so add ribbon to the plot and then draw the line.
You will have to assign the geom_ribbon where on the x axis to plot ymin and ymax. So, add x=n to your aes for geom_ribbon and it should work.
