R help - Sep 2006 - Checking a package: "Foreign function calls without 'PACKAGE' argument:" - what must I do??

In the process of checking a package, I get the warning
 
Foreign function calls without 'PACKAGE' argument:
.Call("tr", ...)
.Call("trProd", ...)
See section 'System and foreign language interfaces' of the 'Writing
R..
 
These functions are called using the wrappers

trX <- function(x, package="gRcox") {  .Call("tr", x,
package="gRcox") }
trXY <- function(x, y, package="gRcox") { 
.Call("trProd", x, y, package="gRcox") }
 
I can't figure out what I am supposed to - and reading the specific section
of "writing R extensions.." does not help me.
 
Can anyone help?
Thanks 
Søren

Get rid of old DOS habit, and realize that R is case-sensitive....
