You really don't have to do that, but just RTFM instead. ?boot says:
statistic A function which when applied to data returns a vector
containing the statistic(s) of interest. [...]
In all other cases statistic must take at least two
arguments. The first argument passed will always be
the original data. The second will be a vector of
indices, frequencies or weights which define the
bootstrap sample. [...]
Your "myFun" clearly does not fit that description. boot() tried to call
"myFun" with a second argument, but "myFun" doesn't know what to do with a
second argument, and that's where you get the error.
