R help - Jun 2012 - Websocket example out of the box failing if running at startup from Rprofile.site

Hello,

 

I run websockets 1.1.1  from R 2.15 without any problems.  I would like
to deploy R script running automatically for all users when R is
starting from Rprofile.site like follow:

 

.First <- function()

{

                source("C:\\R\\orig-websockets.R")

}

 

This script is from websockets package distribution.

 

The error is follow:

 

Error in .parse_header(x) : could not find function "tail"

 

And trace:

 

6: .parse_header(x)

5: service(w) at orig-websockets.R#26

4: eval.with.vis(expr, envir, enclos)

3: eval.with.vis(ei, envir)

2: source("C:\\R\\orig-websockets.R")

1: .First()

 

I would appreciate any suggestions on a subject.

 

Ilya

tail is in the utils package that is not available at that time. You can 
try utils::tail to access it.
