I defined three functions:
> fun0 <- function( x=1:5, y=1:5, ... ) xyplot( y ~ x, ... )
> fun1 <- function( x=1:5, y=1:5, ... ) fun2( y ~ x, ... )
> fun2 <- function( ... ) xyplot( ... )
The call of fun0() works as expected.
The call of fun1() causes the following error:
'Error in eval(expr, envir, enclos) : object "y" not found'
How should I define fun2 to avoid the error?
Thanks - Wolfram
