[R] so current status of interactive PDF creation isl? trying to explore econometriic convergence thread

[Mike Marchywka]

I think I just saw a thread go by on " how do I make interactive PDF from
rgl output" but I ignored it at the time and can't seem to find consensus result
on google. Essentially I wanted to create pdf or other output to 
share a 3D plot and let viewers interact with it but it still wasn't
clear on easiest way to do this. 
Is this 2009 page the best reference?

Thanks.
Specific case of interest is below, 

I found rgl to be quite useful in regards to this,

http://r.789695.n4.nabble.com/maximum-likelihood-convergence-reproducing-Anderson-Blundell-1982-Econometrica-R-vs-Stata-td3502516.html#a3512807


I generated some data points using this script
( which itself uses this data file http://98.129.232.234/temp/share/em.txt )

http://98.129.232.234/temp/share/em.R.txt

After some editing with sed, the output of the above script
made this data file showing some optimization's
"trjectory" according to my variables of interest,

http://98.129.232.234/temp/share/emx.dat.txt

df<-read.table("emx.dat",header=F,sep=" ")




I subsequently found a few ways to plot the data,
notably,

png("em.png")

plot(log(df$V1),df$V2)

png.off()



http://98.129.232.234/temp/share/em.png



png("em2.png")

plot(log(df$V1),df$V2,cex=1+.2*(log(df$V3)-min(log(df$V3))))

dev.off()


http://98.129.232.234/temp/share/em2.png


But what I'd like to do is publish an interactive 3D
plot of this data similar to the rgl output
of this,

df<-read.table("emx.dat",header=F,sep=" ")
library(rgl)
rgl.points(log(df$V1),df$V2,log(df$V3))

quick google search and ?rgl didn't seem
to provide immediate answer.

Is there a way to publish interactive plots?
Thanks.
