Hi all,
A suggestion derived from discussions amongst a number of R users in
my research group: set the default column names produced by aggregate
() equal to the names of the objects in the list passed to the 'by'
object.
ex. it is annoying to type
with(
my.data
,aggregate(
my.dv
,list(
one.iv = one.iv
,another.iv = another.iv
,yet.another.iv = yet.another.iv
)
,some.function
)
)
to yield a data frame with names = c
('one.iv','another.iv','yet.another.iv','x') when this seems more
economical:
with(
my.data
,aggregate(
my.dv
,list(
one.iv
,another.iv
,yet.another.iv
)
,some.function
)
)
