Hi all-
I am trying to visually assess the fit of a model. The model produces as
distribution of predictions and the observation is one point. I would like
to overlay the observation onto a violin plot of predictions. For some
reason the observation does not display in this simple example:
using Gadfly,DataFrames,Distributions
df = DataFrame(x = rep("Observation 1",10000),prediction =
rand(Normal(0,1),10000),observation = rep(.5,10000))
plot(df,layer(x = "x",y="prediction",Geom.violin,width = 2),layer(x = "x",y
=
"observation",Geom.point(),Theme(default_color=colorant"black",default_point_size
= 5pt)
))
Any assistance would be appreciated.
