[BioC] missing xy2i and i2xy functions

[Nisha Mulakken]

Hi,

The hgu133acdf package seems to be missing xy2i and
i2xy functions. 

> get("xy2i", "package:hgu133acdf")
Error in get(x, envir, mode, inherits) : variable
"xy2i" was not found

The get method works for another package:

> get("xy2i", "package:hgu95av2cdf")
function (x, y) 
{
    y * 640 + x + 1
}
>

Please let me know if this is a bug or if there is
something else going on.

Thank you,
Nisha
