I am running the following version of R under Windows 7.

```
R version 3.0.1 (2013-05-16) -- "Good Sport"
Copyright (C) 2013 The R Foundation for Statistical Computing
Platform: x86_64-w64-mingw32/x64 (64-bit)

```

Using library(RODBC), 

```
channel <- odbcConnect(dsn = "database")

ProcExec <- "execute LENGTHCOMP(2004)"  
# the procedure returns nothing, but creates a series of Oracle tables needed later in the R function
sqlQuery(channel = channel, query = ProcExec, believeNRows = FALSE)

odbcClose(channel)

```

returns error:

```
[1] "42000 0 [Oracle][ODBC]Syntax error or access violation."               
[2] "[RODBC] ERROR: Could not SQLExecDirect 'execute LENGTHCOMP(2004)'"   .

```

Library ROracle (August 2013) indicates

dbCallProc-methods 
 Call an SQL stored procedure
Description
 Not yet implemented.

Are their other R packages that provide functionality to invoke a stored PL/SQL procedure on Oracle? or is there a way to make sqlQuery do it from the RODBC package?
