Hi,
I think I remember it was once suggested on this list that DataFrame
objects with numeric columns could support math/summarization
operations, like data.frame objects do (can't find the thread
to provide the link, sorry).
I'll mention that wrapping a DataFrame object (or any matrix-like or
a
Please be more specific about the desired operations, or, better, submt a
pull request with them. colMeans() in particular was intentionally omitted
because it depends on having homogeneous data, which is better suited for a
matrix, not a data frame.

Good day,
Would it be useful to provide the same operations which can be done to a
data.frame for a DataFrame in a future release of S4Vectors? For example,
dataTable <- data.frame(aFeature = 1:5, anotherFeature = 5:1)
colMeans(dataTable)
# aFeature anotherFeature
# 3 3
