Re: the z-scores providing it's normally distributed, you can simply calculate them with pnorm and qnorm:

z<-c(0.67,1,1.64,1.96,2.58)
p<-1-2*(1-pnorm(z))
print(p,digits=2)
# and back
qnorm((p+1)/2)

@ChrisL Do you know if there is a z-value lookup function in R anywhere (I can’t find it)? It could be then used to generalise the funnel plot function further, and allow the user to specify the confidence values that are plotter?

@ChrisL Re: colour and transparency – I’ll try that… I still haven’t got my head round colour palettes etc in ggplot at all yet… there’s a few things I want to try out with heatmaps as soon as I crack it:-)
PS thanks for the feedback:-)

Sorry, I meant “to get the transparency and both the fill and colour options working”. I wanted the shape to be an orange disk with a black circle.
