[Rcom-l] LoadLibrary Error

[ddyudd]

Hi,
   Plentiful  packages are the most charming resources in 
R environment. But I met some questions in application.When loading some 
packages , its function couldn't return result,but 
IStatConnectorCharacterDevice can receive information. This has resulted in 
constructing  a complex function on the basis of loaded package is 
difficult. Code as follow:  
               
 R myR=new R();
               
 myR.loadLibrary("fCalendar");
              
 
               
 string tet= myR.evaluateAsText("x=search()");
               
 string tet2 = myR.evaluateAsText("x<- Sys.timeDate()");
&nbsp;# test2&nbsp;received&nbsp;as : 2008-09-20 23:11:10&nbsp; ;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
 object tet3 = myR.GetSymbol("x");&nbsp; # occur Error!
----------------------------------------------------
public string evaluateAsText(string cmd)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; string 
cmdprint = cmd.StartsWith("print") ? cmd : "print(" + cmd + ")";
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
Output.Clear();&nbsp; # &nbsp; public RCharDev Output { get { return 
_characterDevice; } }

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; try
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
 EvaluateNoReturn(cmdprint);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; catch { }
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; string txt = 
Output.Text;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if 
(txt.ToLower().IndexOf("error") >= 0)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
 throw new Exception("evaluateAsTextException:" + txt);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
Output.Clear();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return txt;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
----------------------- ( Thanks everyone observed advance
