Rcpp integration for the Armadillo templated linear algebra library
Hi, I'm working on a MCMC estimation algorithm by using "RcppArmadillo", but got the error message "warning: chol(): given matrix is not symmetric" and the algorithm stops due to this...
Issue https://github.com/RcppCore/RcppArmadillo/issues/263, opened quite some time ago by @coatless, demonstrated that we had a bug stacked away in dealing with a field exporter which dropped a dimension. I worked a...
I encountered a bug in RcppArmadillo when saving a row of a cube to a matrix. If one of the remaining dimensions is just of dimension 1, then dimensions are...
Stumbled across an interesting hiccup in the exporter for `arma::field` (the generic vector). In particular, the attributes associated with an `arma::field` shows as `matrix` under a `class(x)` call instead of...
Glancing over the RcppArmadillo code, the [Alt RNG setup directly uses R's RNG for uniform (e.g. `Rf_runif()`](https://github.com/RcppCore/RcppArmadillo/blob/master/inst/include/RcppArmadillo/Alt_R_RNG.h#L74-L81). However, the extension code in [`inst/RcppArmadilloExtension/sample.h`](https://github.com/RcppCore/RcppArmadillo/blob/master/inst/include/RcppArmadilloExtensions/sample.h#L35-L40) does not. So, likely this will need...
If you are encountering issues installing `RcppArmadillo` on macOS, please use the `macrtools` package here to install it: You can read more about setting up compiled code on mac here:
When we updated RcppArmadillo recently to help package Matrix propagate a change, we encountered a small change in Armadillo made between the 11.2.0 and 11.2.3 releases that marked our previous...
Conrad has been busy preparing a new release 14.0.0 of Armadillo. A release candidate 14.0.0 rc1 exists and has been announced. I have been testing different iterations leading up to...
It seems like the CRAN r binary is now shipping with built-in libomp headers! So, the check inside of [`configure.ac`](https://github.com/RcppCore/RcppArmadillo/blob/37461ba36472305c699263afc229919d37daa5e3/configure.ac#L109) and the [`inline` plugin](https://github.com/RcppCore/RcppArmadillo/blob/37461ba36472305c699263afc229919d37daa5e3/R/inline.R#L20) might need to be tweaked to...
ARMA_64BIT_WORD is useful for extended ranges and longer indices beyond the scope of a 32-bit integer. A reverse-dependency check is revealing that we cannot enforce it as a few dozen...
