Intro to R

Introduction

R is a good tool in your toolbox to manipulate and visualize local data. Even if you can only make bar charts and line charts, it can be very useful compared to only display the data in text. It also has a nice IDE (RStudio).

When you look for answer in stackoverflow about R, you might have many wtf moment. There are many absurd-hacky answers that people gladly offer. This is often frustating. I think this paragraph resembles a lot with R situation:

Just for reference, 80% of awful Perl "code" in my $work falls under this - it was written by financial analysts who are smart enough to pick up a Perl book and some earlier scripts, clone off a script that does what business need is, and don't have CS/programming background to worry about how readable/maintainable their code was. - from stackoverflow

This short guide shows a minimal way to get something done in R.

Addons

It'll be created as the part of kube-system namespace, so basically just install the addons using this command for testing purpose:

cd kubernetes/cluster/addons/fluent-elasticsearch
kubectl create -f es-controller.yaml
kubectl create -f es-service.yaml
kubectl create -f kibana-controller.yaml
kubectl create -f kibana-service.yaml

int T, r, c, i, j, flow,H,W;
char m[MAXF][MAXF];
bool vis[MAXV];
int res[MAXV][MAXV], p[MAXV];
