[Rd] "[.data.frame" allows un-named 3rd subscript (PR#989)

[cberry@tajo.ucsd.edu]

Since the Extract page has usage as:

     x[i, j, ... , drop=TRUE]

I would expect that 'drop=' would need to be given to the third 'subscript'

> diag(4)[ , 4 , 4 ] # Forgot 'drop=' or added extra ','
Error in diag(4)[, 4, 4] : incorrect number of dimensions
> 
> as.data.frame( diag(4) )[ , 4 , 4 ] # should return error, right?
[1] 0 0 0 1


Also note:

> diag(4)[ ,  , drop=TRUE ]
     [,1] [,2] [,3] [,4]
[1,]    1    0    0    0
[2,]    0    1    0    0
[3,]    0    0    1    0
[4,]    0    0    0    1
> 
> as.data.frame( diag(4) )[ ,  , drop=TRUE ]
Error in [.data.frame(as.data.frame(diag(4)), , , drop = 4) : 
	Argument "j" is missing, with no default
