Dear Thomas,
I know the meaning of "error 2042 "&" -2146826246" is "NA".
What confused me is if i execute the command " x<-c(TRUE,FALSE,NA)", the
first returned value is "FALSE" but not "TRUE" in both VB6.0 and C#3.5
this is the test code
Set r = CreateObject("StatConnectorSrv.StatConnector")
r.init "R"
r.Evaluate("x<-c(TRUE,FALSE,NA)")
if i track r.Evaluate("x<-c(TRUE,FALSE,NA)") in "Watches " windows, i will
see the error returned values(in the hyperlink below)

error 2042 is NA. Speaking in COM terms, the VARIANT type is VT_ERROR, the
value is 2042. This is what some apps, e.g., Excel, will send for NA values.
