# Tuesday

• Confirm travel plans for tomorrow

### pdg-control

• Stability analysis
• speeding up policycosts (extra loop) will probably require some C coding. Meanwhile could hard-code in the profit function to accelerate things.
• model averaging (mimic the fisheries science work & climate models that present distribution of outcomes over different models as the range of possibilities, lacking probabilities assigned to those models…).
• work on model estimation
• externalization: Note that we can tangle a file to create a .R script that can be used for externalization, rather than having to copy-paste the chunks. Nice if we want to source in rather than knit a file too.

### Treebase

• Treebase manuscript writing…
• having to knit from R terminal, trouble with makefiles and knit script?

need to use require(methods) and require(utils) separately?

### Computing

• Updated the pmc vignette successfully.
