NodeJS - install package - plotly.js

Installing a package using npm:

:~$

Now, we install plotly.js using the following command:

~$ npm install plotly.js
npm WARN deprecated nomnom@1.8.1: Package no longer supported. Contact support@npmjs.com for more info.
npm WARN saveError ENOENT: no such file or directory, open '/home/ubuntu/package.json'
npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN enoent ENOENT: no such file or directory, open '/home/ubuntu/package.json'
npm WARN ubuntu No description
npm WARN ubuntu No repository field.
npm WARN ubuntu No README data
npm WARN ubuntu No license field.

+ plotly.js@1.35.2
added 495 packages in 70.718s
~$

After, plotly.js is installed we can check for its documentation using the explore command:

~$ npm explore plotly.js
~$

Looks like local documentation is not available. Hence, let us check its online documentation using the following command:

~$ sudo npm docs plotly.js

This command opens the online documentation in your default browser.

Julia - Language - Install Juno Text Editor

To Install Juno text editor, first install Atom text editor, created by GitHub. Download the Debian package of Atom from the link: https://atom.io/

Download Atom text editor:

Now install using the dpkg utility of debian / ubuntu / linux mint:

$ sudo dpkg -i atom-amd64.deb
Selecting previously unselected package atom.
(Reading database ... 174639 files and directories currently installed.)
Preparing to unpack atom-amd64.deb ...

Errors were encountered while processing:
atom

We can see that there were some errors due to missing dependencies. Hence to resolve them, let us run:

$ sudo apt-get install -f

This will install atom. To confirm, let us run the following commands:

$ which atom

/usr/bin/atom

$ atom --version

Atom : 1.19.0

Electron: 1.6.9

Chrome : 56.0.2924.87

Node : 7.4.0

In Atom, go to Settings (Ctrl ,, or Cmd , on OS X) and go to the "Install" panel.

Type uber-juno into the search box and hit enter. Click the install button on the package of the same name.

Atom will then set up Juno for you, installing the required Atom and Julia packages. Once the setup is done you're good to go!

Refer: https://github.com/JunoLab/uber-juno/blob/master/setup.md

We see, dataset is a function which takes two arguments.

package name
dataset name within package which we intend to load

This, we have loaded the famous iris dataset into memory. We can see that the dataset function has returned a DataFrame. This dataset contains 5 columns.

SepalLength
SepalWidth
PetalLength
PetalWidth
Species

Also, the data can be easily understood. A large number of samples have been taken for every species, and the length and width of sepal and petal have been measured which can be used later to distinguish between them.
