I am working with R for few weeks and I am trying to use it for my following scenario.

1)I have a java code that is receiving streaming data on a thread
2) am hoping to instantiate R some how (may use one of rjava,jri,rserv; not yet sure which one is right)
3) how can I draw scatter plot with this streaming data. Should I recreate plot with newly created data frame? If so, I am getting data at every second and recreating plots may not be efficient. I would like to have a solution in R, where I will add this new data to existing plots.

I am looking to draw plots in R, because I am going to represent this data in multiple graphs (including the output of regression graphs every 10 mins). I looked into shiny package, but shiny (as I understand) doesn't take external data sets
