# R-PARCEL

This repository is aim to create R parcel.

## Prerequisity

You need to install Docker. I confirmed with Docker community edition on Ubuntu.

## Simple way to build Parcels

After installation of Docker, run:

```

$ ./build.sh

```

You will find parcels in `./target` directory.

## Manual build

### Preparation

Prepare R environment using miniconda.

```

$ mkdir -p ./target/CONDAR-3.4.1/lib

$ cp -r ./source/meta ./target/CONDAR-3.4.1/

# (Option) Modify meta/parcel.json if needed

# $ sed -i s/__OS_VERSION__/el6/g ./target/CONDAR-3.4.1/meta/parcel.json

$ docker build -t chezou/condar:centos7 -f centos7.Dockerfile .

# Open another terminal and find your container.

$ docker run -it -t chezou/condar:centos7 /bin/bash

$ docker ps

$ docker cp -L :/opt/conda/envs/R_env ./target/CONDAR-3.4.1/lib/conda-R

# Terminate docker process

```

### Modify meta data

In current version, you should modify version info in json.

### Tar your Parcel

```

$ cd target

$ tar cvzf  CONDAR-3.4.1-el7.parcel CONDAR-3.4.1 --owner=root --group=root

```

### validate, create metadata.json

I borrowed validator.jar and make_manifest.py from [cm_ext repo](https://github.com/cloudera/cm_ext).

#### How to validate json and parcel

See also: [How to use validator.jar](https://github.com/cloudera/cm_ext/wiki/Building-a-parcel#validation)

```

$ java -jar lib/validator.jar 

```

At least, you should pass parcel test:

```

$ java -jar lib/validator.jar -f target/CONDAR-3.4.1-el7.parcel

```

#### How to create manifest.json

Run following command, then you'll get `./target/manifest.json`.

```

$ python ./lib/make_manifest.py ./target

```

### Put the Parcels into your http server

Upload every `./target/*.parcel` and `./target/manifest.json` to the same directory on http server.

You can put Parcels on S3. It doesn't need to have index.html for directory listing.

## FAQ

### How to control R version?

This parcel use Miniconda to install R. You can controll R version with setting [r-essentials](https://anaconda.org/r/r-essentials)' version.
