H2O va bien (muy bien) tanto en un ordenador sobremesa/portátil y sobre un clúster. En uno de sobremesa si tienes buena RAM y muchos cores, mejor.

Dear, I'm following the r tag on stackoverflow.com, and couldn't but notice there are quite some questions popping up that deal with scoping in relation to custom functions.

For those of that are fans of stackoverflow.com, and stackexchange.com, there's an effort to define a telephony stackexchange site. It's still in the definition phase. What it needs to move forwards is more votes on on/off topic questions, and perhaps some better questions to vote for or against.

Hello fellow downstream residents, I see that r358546 accidentally deleted an entire subtree, which was reverted in r358552. This of course caused a big merge conflict in our local repo, and internally we've been debating tactics for dealing with it, hopefully without losing our original history. Has anyone else handled this in a way that they are happy with? We found a StackOverflow

You may use specifications of the geometry package rather than specifying options to the class: e.g. replace your current header: --- title: "Testing landscape and aspect ratio" output:
