Supplement to Homework 12

If your Latex distribution is missing sty files

• You can copy missing sty files into your working directory from the internet .

• Better, you can get a more complete Latex distribution. If you install Xcode, Xcode command line first, and MacPorts (all of which are good to have for scientific computing) you can open a terminal and run

sudo port install texlive-latex-extra

• If you do not have Latex on your laptop, and it is a UM laptop, you can install MacTex via the Managed Software Center. Once this is installed, and your machine is restarted, then you can check that pdflatex is on the search path by typing in a terminal

which pdflatex

If you have problems running the code in Rstudio

• Note that the homework does not ask you to use Rstudio. You can just run R in a terminal window.

• Using Rstudio sometimes introduces problems. This is fairly rare, but in this particular case it happened to several people that Rstudio behaved inappropriately with the Rnw file.

• In general, stripping away an unnecessary layer of code (here, Rstudio) is worth trying when debugging.

Installation of missing packages

• Most people will have to install missing R packages. It is no longer practical to keep up-to-date copies of all CRAN packages on our machine.
