There is a further option within the Mat constructor, which when used
should prevent this error.
Specifically, we have:

Here is a simple fix: just _join_ the matrix and the col vector.
Result first (now with set.seed(42), so rngs different)

That is not a method I've used, I think, so I will defer comments.

Hello,
I had a problem this afternoon with an arma::mat constructor and the
mat::insert_col method. Since I got the example from Dirk, I thought I would
point out the problem I had and a solution. See

All right! I think I have it figured out, at least for the toy

What wasn't compiling wasn't my functions, it was RcppExports.cpp.
sourceCpp (and hence also the knit example) have been working for me all
along. The only issue (apparently) was that RcppExports.cpp was not

Good.

Alex,
Thanks to Mike, we do have one public, posted, working example of Rcpp and
bigmemory in the Rcpp Gallery:

So before we go any further with this, can you please confirm that you manage
to re-build that example (once you grab t
Hello again,
Thank you for looking over my issue and sorry for not giving reproducible
code. I guess assumed that I was doing something obviously wrong but just
didn't see it.
I did add an entry for bigmemory (and Rcpp) in the DESCRIPTION file for
both the Depends and LinkingTo fields.

Hi to all,
I was investigating a way to write with Rcpp a function that removes all
the NA values in the input vector.
And before doing so, I was playing with Rcpp, writing this function:
