[R] sqlSave()

[Felipe Carrillo]

Sorry, I'am resending it because I forgot to send my system info(below)

Hi all: 
I have created a MS Access table named 'PredictedValues' through the statement below:
myDB <- odbcConnectAccess("C:/Documents and Settings/Owner/Desktop/Rpond Farming.mdb",uid="admin",pwd="")    
sqlSave(myDB,PredictedValues,rownames=FALSE)
  close(myDB) 

But if I run the code again with new values I get the message below:
Error in sqlSave(myDB, PredictedValues, rownames = FALSE) : 
  table ‘PredictedValues’ already exists
and my new records don't get updated.

I was under the impression that 'sqlSave' would copy new data on top of the existing one or if the table didn't exist it would create one with the new values. I tried 'sqlUpdate' but my existing 'PredictedValues' didn't update. What am I doing wrong.
?
