[R] Reshape:cast; error using "..." in formula expression.

[misterbray]

Whenever I use "..." in the formula of the cast function, from the reshape
package, I get the following error:

Error in `[.data.frame`(data, , variables, drop = FALSE) : 
  undefined columns selected


For example:

data(french_fries) #available in the reshape package
> head(french_fries)
   time treatment subject rep potato buttery grassy rancid painty
61    1         1       3   1    2.9     0.0    0.0    0.0    5.5
25    1         1       3   2   14.0     0.0    0.0    1.1    0.0
62    1         1      10   1   11.0     6.4    0.0    0.0    0.0
26    1         1      10   2    9.9     5.9    2.9    2.2    0.0
63    1         1      15   1    1.2     0.1    0.0    1.1    5.1
27    1         1      15   2    8.8     3.0    3.6    1.5    2.3

>cast(french_fries, ...~ subject)
