##### Random Walk and autoregressive process

x_t follows a data generating process based on the normal distribution. The data generating process depends on the previous observation plus an error term: x_t = rho x_{t-1} + e_t

##### Plot many variables with lapply and ggplot

I want to visualise all series in the example dataset airquality: Ozone, Solar.R, Temp and Wind. There are 2 ways to do it:
Call ggplot many times on each column name
Call ggplot once on a reshaped dataset in long format

##### GFPMoutput to explore GFPM simulations

GFPMoutput is a an R package that converts DAT files output of GFPM PELPS folders (see http://labs.russell.wisc.edu/buongiorno/welcome/gfpm/) into data frame structures. The GFPMouput package can be used to plot consumption, production and trade volumes for more than 2 scenarios and to automate various calculations such as welfare and value added.

##### Time Series

Inspired by Tavish Srivastava’s step by step guide to learn time series modelling. Use rnorm() to generate the error and use Reduce(accumulate=TRUE) to calculate a random walk.
