trimfill {metafor} | R Documentation |
The function trimfill
is generic. It can be used to apply the trim and fill method proposed by Duval and Tweedie (2000a, 2000b; see also Duval, 2005) to specific classes of objects.
trimfill(x, ...)
x |
an object of class "rma.uni" . |
... |
other arguments. |
Currently, there is only a method for objects of class "rma.uni"
created by the rma.uni
function. Accordingly, the corresponding method is called trimfill.rma.uni
. See the documentation for that function for more details.
