[R-SIG-Finance] Introducing TFX: An R Interface to the TrueFX Web API

[G See]

Aw. That's a shame.  What version of shiny and websockets are you using?

Maybe try:
   devtools::install_github('shiny', 'rstudio')

It works for me on linux with the following sessionInfo

> sessionInfo()
R version 2.15.2 (2012-10-26)
Platform: x86_64-pc-linux-gnu (64-bit)

locale:
 [1] LC_CTYPE=en_US.UTF-8       LC_NUMERIC=C
 [3] LC_TIME=en_US.UTF-8        LC_COLLATE=en_US.UTF-8
 [5] LC_MONETARY=en_US.UTF-8    LC_MESSAGES=en_US.UTF-8
 [7] LC_PAPER=C                 LC_NAME=C
 [9] LC_ADDRESS=C               LC_TELEPHONE=C
[11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base

other attached packages:
[1] bitops_1.0-4.1 TFX_0.1.1      shiny_0.1.12
