Hi,
I notice that the CRAN binary for the macOS version of RProtoBuf is
built against quite an old version of protocol buffers (from 2014,
before v3 format support was added).
the windows version is (blessedly) kept up-to-date, but I'd like to

Probably something went wrong earlier in the build when compiling the
Matrix package. However it's much easier to install R form the

Hi all,
Is there are base function that I've missed that tests if an object is
a vector in the dimensionality sense, rather than the data structure
sense? i.e. something that checks is.null(dim(x)) ?
is.vector() is trivially disqualified since it also checks for the
presence of non-names

Can you clarify what you mean by dimensionality sense and specifically 1d
here?
You can have a 1d array which is different from what your
Thanks, Hadley for bringing this up:-)
I am teaching R and I can suggest 5 different definitions of 'vector':
a) vector as a collection of homogeneous objects, indexed by [ ] (more
precisely atomic vector). Sometimes you hear that in R, "everything is a
vector", but this is only true for atomic
