I'd like to introduce the TFX package which I recently published to CRAN.
It is a simple R interface to the free TrueFX Web API. You can use it
to get real-time quotes with millisecond resolution and fractional-pip
bid/ask spreads for 26 currency pairs.
There is an RPub overview of the TFX package available here:

Wow, this looks _very_ cool! Thank you for all the R work you do.
# install.packages('shiny', repos=c('http://rstudio.org/_packages',
# getOption('repos'))
library(shiny)
runGist("4122626")
Runs with no problems here. Starts a Chrome session on localhost:8100.
#--------------------------
The code for the above shiny app can be viewed or downloaded from
https://gist.github.com/4122626
Did that, pasted server.R and ui.R into ~/R/gsee/, then within
an interactive R session, did:
runApp(appDir = '~/R/gsee', port = 8100L)
It runs as before, and after opening up port 8100, the world can see
it. Amazing. Firefox 16.x and Chrome 20.0.1132.57 both work.

I've also had a little bit of success creating real-time streaming
charts using svSockets, following the video
(http://www.youtube.com/watch?v=rvT8XThGA8o) on the data.table
homepage (http://datatable.r-forge.r-project.org/) as a template and
using TFX as the data source.
Love to see this in action.
Hope it's useful,
Looks as if it will be very useful indeed. :)
Thanks again,
