I copied and pasted the code for Shiny app, but it doesn't update the FX quotes
every 750 ms. I tried it on Firefox and Chrome.

[sorry for the previous HTML e-mail. Gmail seems to think that's what
I meant to do]

Hello all,

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:
http://rpubs.com/gsee/TFX

The shiny package (http://www.rstudio.com/shiny/) has made the TFX
package more relevant (at least to me). You can see a demo of using
TFX with shiny by running the following code which will open a browser
window and display FX quotes that update every 750 milliseconds:

# install.packages('shiny', repos=c('http://rstudio.org/_packages',
# getOption('repos'))
library(shiny)
runGist("4122626")
#--
The code for the above shiny app can be viewed or downloaded from
https://gist.github.com/4122626

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.

Finally, TrueFX provides historical tick data for 15 currency pairs
going back to May 2009 (http://truefx.com/?page=downloads). There is a
script in the inst/parser directory of the FinancialInstrument package
(www.tinyurl.com/DownloadTrueFX) that can be used to download all of
that data to disk in a format that FinancialInstrument::getSymbols.FI
can easily read. This script is not intended to be used on Windows.

I have no affiliation with TrueFX.

Hope it's useful,
Garrett

P.S. The RPub (http://rpubs.com/gsee/TFX) is also included as a
vignette in the R-Forge version (installable with
install.packages("TFX", repos="http://r-forge.r-project.org";). As
outlined in the NEWS file, the only updates in the R-Forge version are
aesthetic: there are better error messages, a print.TFXsession method,
and Reconnect and Disconnect no longer print the returned TFXsession
object.

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

"I copied and paste" ? Maybe you did that the wrong way?  

What happens when you install the shiny and TFX packages, and execute

library(shiny)
runGist("4122626")

which has been very reliable for me on different machine 
(home/work/netbook/...) ?

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

[Dennis Lee]

I am running it on Windows, maybe you didn't understand what I said.

I did get the first quote displayed correctly, so it is not because of the 
library.

My problem is that it doesn't update periodically. I will try to figure it out
when I have time, just too late now (its past midnight here) to solve this.

> sessionInfo() R version 2.15.1 (2012-06-22)

It could be because of my R version (maybe not), but then again I have 

installed the CRAN version of shiny (and not the dev version on Github).

If the backend is using websockets, that is very new ground in the land of
HTML.  M$ prides itself typically on being off by a decade w.r.t. adoption
of such 'shiny' things.

So... that may indeed be your issue.

Another possibililty, of course, is that you checked the "Pause
updates" check box at the bottom of the page.  When that is checked,
the quotes don't update.

I did get this warning when I ran the code:

> was built under R version 2.15.2 

I have checked websockets:

I have checked pause updates:

So, Windows is not the issue, I have to update R to version 2.15.2 then
seems logical to me.

But, I ran it on R 2.15.1 and it worked fine.  See my sessionInfo in
the previous message.

So, I'm not sure what's not working for you.  Maybe some local
security settings?

websockets are _incredibly_ browser sensitive, as I noted before.  I worked
on/with the websockets package back when Bryan Lewis first wrote it, and to
say getting the pieces aligned is tricky is an understatement.

I don't know the current browser status, but you may need to update those
as well.

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

[rex]

G See  [2012-12-03 04:57]:

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:
http://rpubs.com/gsee/TFX


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.


sessionInfo()

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,

Try typing that command.  Your single quote is a weird character.  Try this:

id <- ConnectTrueFX('EUR/USD,GBP/USD', username='veepsirtt',
  password='veeps203')

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

[G See]

Because you've pasted a right single quote unicode symbol instead of
typing an apostrophe.

When I copy/paste from the command you entered, I get

R> charToRaw("’")
[1] e2 80 99

When I type an apostrophe using the keyboard, I get

R> charToRaw("'")
[1] 27

Try typing your command instead of copy/pasting it.

Hope this helps,
Garrett

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

[G See]

you entered a less than sign instead of an assignment operator.

instead of
  id < ConnectTrueFX(...
it should be
  id <- ConnectTrueFX(...
