Hi

there seems to be an error in the documentation of the "merge" function:

Arguments:

    x, y: data frames, or objects to be coerced to one.

  by, by.x, by.y: specifications of the common columns.  See ‘Details’.

     all: logical; ‘all = L’ is shorthand for ‘all.x = L’ and ‘all.y =
          L’.


The "L" should be a T or a TRUE.

Cheers,

Rainer
