Shiny Application for iNZight.

iNZight Lite version 1.0

Last Updated: 06/05/16

This is the online version of iNZight (http://docker.stat.auckland.ac.nz), with four new modules:

• Visualize
• Time Series
• Model Fitting

Underway:

Recent Updates (Most to least recent):

• [Missing to categorical] Made the "missing to categorical" function to be consistent with iNZightVIT
• [Visualize] Fixed the problem of "when g2_level == 0, doesn't show plots"
• [Visualize] Get rid of "none" option for the selectinput box of variable 1. Now when users go to "visualize" page, it directly shows the plot of the first column
• [Visualize] The smallest pch size for dots plot is reset to be 0.1 (was 0.05)
• [Visualize] Fixed the problem of the "none" option for the 1st subset variable
• [Filter Dataset] Go back to "visualize" page after filtering the dataset, all the variable slections are cleared and users can select variables to be plotted again based on filtered dataset
• [Visualize] Fixed the "RESET ALL" function
• [Visualize] Fixed the problem of displaying summary and inference for a numeric varibale
• [Visualize] Fixed the problem of considering NAs as a single category
• [Import dataset] When users switch a page from "visualize" or other analysis modules back to "import dataset", old dataset preview table doesn't disappear
• [Import dataset] Users are able to upload new dataset without removing old dataset or refreshing page

• [Import dataset] fixed importing dataset from url
• [Visualize] "none" option added for selecting first variable.
• [Global] Implemented GET variables to add to iNZight-lite URL.
• [Visualize] All "Advanced options" are now up to date with iNZight.
• [Model Fitting] Implement the model fitting module
• [Time Series] Check if it can handle datasets with the "DATE" columns in column 2+.
• [Time Series] Fix "Provide Time Information".
• [Help] This module was removed. Even though it is in iNZight links to the new webpage already exist in the "About" start page and help to every module is available for every module inside the modules.
• [Visualize] Add inferential markups once Tom finishes updating iNZightPlots().
• [Advanced] Nest QE and TS under "Advanced".
• [Quick Explore] Merge into 1 tab.

• [Data Import] URL support added (CK).
• [Quick Explore] Single column plot update - player feature (CK).
• [Time Series] Added shiny validation messages and modified the input panel so that only "Provide Time Information" is shown if the data set has no time variable defined in a format recognized by iNZightTS() (CP).
• [Visualize] Fixed the "Reset All" button (CP).
• [General] Updated help.md files for the "Time Series" and "Visualize" modules and created a template for use in other modules in /panels/0_Template/3_panelname-panel-help.md (CP).
• [General] Fixed Datatables bug (CK).

Package dependencies

This are all the packages which are loaded by iNZight lite. Please install all dependencies.

• iNZightPlots
• iNZightTS
• iNZightMR
• markdown
• GGally
• gpairs

Directories:

• data: This directory holds all the data. The data must be placed in sub-directories, which will come up as data categories within iNZight-Lite.

• gui-elements: (removed) This directory contains the gui functions for all the old modules (from iNZight revamp).

• www: This directory is used for graphics and/or web-related files such as .css and .gif/.jpeg/.png javascript files. Images are stored in a sub-directory called "images". Javascript code is stored in a subdirectory "js".

• panels: This directory contains the gui, server, help, and other functions for each module.

Main files:

• README: Documentation for iNZight Lite. Update as required.

• global.R: Defines functions and variables that are used globally. For now, all non-GUI functions are stored here.

• server.R: Script for shiny server.

• ui.R: Defines the main GUI.

• functions.R Defines al functions used in iNZight-lite, some of them are also in iNZightTools.

Note:

This repository will gradually be changed into the following format throughout 2015:

• data: This directory holds all the data. The data must be placed in sub-directories, which will come up as data categories within iNZight Lite.

• www: This directory is used for graphics and/or web-related files such as .css and .gif/.jpeg/.png. Images are stored in a sub-directory called "images".

• panels: This directory contains the gui, server, help, and other functions for each module. The directory/file names will be of the form:

  • [Directory] N_(sub-)panel-name
  • [File] 1_panelname-panel-gui.R
  • [File] 2_panelname-panel-server.R
  • [File] 3_panelname-panel-help.R
  • [File] 4_panelname-panel-null.R
  • [File] 5_panelname-panel-other.R
