Monday

• Trivial example of a non-optimal but more robust policy by editing the optimal strategy directly. Note in particular that this outperforms the optimal strategy economically as well as ecologically (fewer crashed populations).

• Running the policy-costs model with Beverton Holt instead of the Myers function seems to give a clearer picture of a system responding to policy costs. The single-replicate picture probably captures this better than the policy/replicate visualizations..

• Setup flickr options (tags, description, title, etc) example

• Updated pmc to handle errors (mostly from svd failures in geiger). Also updated vignette.

Failing to declare the XML namespace was causing my simple xml parsing example to fail.

thing = xmlParse(getURL("https://github.com/cboettig/pmc/commits/master.atom"))
nds = getNodeSet(thing, '//x:entry', namespaces = c(x='https://www.w3.org/2005/Atom'))
length(nds)

success. thanks Gabe.
