Install RStudio Server and polmineR on amazon EC2

ec2.Rmd

After creating the Linux virtual machine on amazon EC2, the hard part was to set the Security Groups correctly to have port 8787 open, and to connect the newly defined Security Group to the instance. After that, everything ran smoothly as follows:

## Add CRAN mirror to sources.list, including key

```{sh}
sudo sh -c 'echo "deb http://cran.rstudio.com/bin/linux/ubuntu xenial/„ >> /etc/apt/sources.list'
gpg --keyserver keyserver.ubuntu.com --recv-key E084DAB9
gpg -a --export E084DAB9 | sudo apt-key add -
```

## install R

```{sh}
sudo apt-get update
sudo apt-get r-base
```

## install apache webserver

```{sh}
sudo apt-get install apache2 apache2-doc 
sudo /etc/init.d/apache2 start
```

## install rstudio server

```{r}
sudo apt-get install gdebi-core
wget https://download2.rstudio.org/rstudio-server-1.0.136-amd64.deb
sudo gdebi rstudio-server-1.0.136-amd64.deb
```
## create some user

```{sh}
useradd -m USERNAME
passwd USERNAME
```

## install system requirements for rcqp package

```{sh}
sudo apt-get install bison
sudo apt-get install flex
sudo apt-get install libglib2.0-dev
apt-get install libpcre3 libpcre3-dev
sudo apt-get install libncurses5-dev libncursesw5-dev
```

## optionally: install corpus workbench

```{sh}
sudo apt-get install subversion
svn export http://svn.code.sf.net/p/cwb/code/cwb/branches/3.0 cwb-3.0
cd cwb
nano config.mk
# linux-64, standard installation (otherwise, things will be in a dir not on the path, cl.h will not be found)
make clean
make depend
make all
```

## meet system requirements for devtools R package 

```{sh}
sudo apt-get install libcurl4-openssl-dev
sudo apt-get install libssl-dev
sudo apt-get install libssh2-1-dev
```

## install R packages 

```{r}
install.packages(pkgs = c("RUnit", "devtools", "plyr", "tm"))
install.packages("rcqp")
install.packages("polmineR")
```

## install corpus

```{r}
library(polmineR)
install.corpus("europarl.en", repo = "http://polmine.sowi.uni-due.de/packages")
```
NOTE: There is a bug in the header file for CWB 3.4 - working with CWB 3.0 preferred 

```{r}
devtools::install_github("PolMine/polmineR.Rcpp")
```

```{r}
install.packages("ggplot2")
install.packages("xts")
install.packages("RColorBrewer")
install.packages("wordcloud")
```
