[R] help - "Object is static, operation not allowed" Error

[WeiQiang.Li@seagate.com]

Hello Dirk,
      Thanks for your quick reply.
      They are simple R codes and working well in RGUI. DCOM is also
communicating well with R, the lineStr=StatConn.Evaluate("x
<-matrix(c(1,2,3,4,5,6,7,8,9),3)") return back return correctly. Only
seldom R codes called failed, and I suspect that the static library loaded
failed even there is no error return after call the line
StatConn.EvaluateNoReturn("library (mva)") . I need this problem fixed
urgently. I hope someone may help me.

      Thanks again!

As a general rule, I found it helpful to disentangle matters:

i)  make sure you really do have working R code, e.g. by actually running
    that code in the Gui

ii) make sure you really do talk back and forth between your controlling
    app and R; so send some data over the wire, alter it and see if you
    it back --- also make sure that you cover the data type you intend to
    send in i)

Hope this helps, Dirk
