Which version of RStudio? See Help -> About | I haven't been able to pinpoint the reason or minimal example. Have anyone else experienced similar issues or is it just me i.e. error in my own implementations? There are a lot of dependencies here [re-indented by me]: Suggests: KFAS (>= 1.2.1), knitr (>= 1.11), rmarkdown (>= 0.8.1), testthat, bayesplot Imports: coda (>= 0.18-1), diagis, ggplot2 (>= 2.0.0), Rcpp (>= 0.12.3) LinkingTo: BH, Rcpp, RcppArmadillo, ramcmc, sitmo We do know Boost interactions (between code compiled 'by us' as R extensions using Boost, and RStudio itself also using an older version of Boost) had thrown spanners in the past. A while back Kevin updated RStudio internals and shielded "their" Boost better. I happen to run RStudio "Daily" builds on all my machines -- those have the fix and "behave".
