[datatable-help] svSocket+data.table

[G See]

I saw the svSocket + data.table video on the data.table project home
page.  It looks pretty cool, so I am trying to implement it.  I can
get it to work with a data.table if I save the data.table to a file,
put the file on the server and load it.  However, I cannot figure out
how to create a data.table on the server, or to send a data.table to
the server.

First, I start R and run this:

    > library(svSocket)
    Loading Tcl/Tk interface ... done
    > startSocketServer(port=8888)
    [1] TRUE

In a second instance of R, I run this:

    > library(svSocket)
    Loading Tcl/Tk interface ... done
    > con <- socketConnection(port=8888)
    > evalServer(con, library(data.table))
    [1] "data.table" "svSocket"   "stats"      "graphics"   "grDevices"
    [6] "utils"      "datasets"   "methods"    "base"

    > evalServer(con, "x <- as.data.table(mtcars)")
    Error in source(objcon, local = TRUE, echo = FALSE, verbose = FALSE) :
      objcon:32:67: unexpected '<'
    31: "drat", "wt", "qsec", "vs", "am", "gear", "carb"), row.names = c(NA,
    32: -32L), class = c("data.table", "data.frame"), .internal.selfref = <

                        ^
If I try to create the data.table in the client and send it to the
server, R just hangs and I have to hit Ctrl+c to break.

    > library(data.table)
    data.table 1.8.3  For help type: help("data.table")
    > evalServer(con, x, as.data.table(mtcars))
    ^C
    Warning message:
    In dump("..Last.value", file <- .f) : deparse may be incomplete

Simple things work fine:

    > evalServer(con, x, 1)
    [1] TRUE
    > evalServer(con, x)
    [1] 1

Also, I should mention that I can run `as.data.table(mtcars)` just
fine from either terminal without using `evalServer`

It appears that there may be a problem parsing the .internal.selfref attribute.

What am I doing wrong?  Is this beyond the expected use-case?

Thanks,
Garrett
