+# wilson 2.0.0 
+## Features
+- clarion class:
+  - easier data-format validation by providing several checks
+  - simplified module usage (only forward clarion object) for top-level modules (e.g. filter & plot)
+  - provide functions for frequent tasks (e.g. get_name, is_delimited, etc.)
+
+- geneView: 
+  - group columns by one or more factors
+
+- pca:
+  - color & shape grouping by selected factor(s)
+
+- scatterPlot:
+  - add name to hovertext if available (only interactive)
+
+## Misc
+- improved notifications (closable, more)
+- overall code quality improvements via usage of packages goodpractice and lintr
+- removed deprecated colorPicker

 CLARION is a data format especially developed to be used with WIlsON, which relies on a tab-delimited table with a metadata header to describe the following columns. It is based on the Summarized Experiment format and supports all types of data which can be reduced to features and their annotation (e.g. genes, transcripts, proteins, probes) with assigned numerical values (e.g. count, score, log2foldchange, z-score, p-value). Most result tables derived from RNA-Seq, ChIP/ATAC-Seq, Proteomics, Microarrays, and many other analyses can thus be easily reformatted to become compatible without having to modify the code of WIlsON for each specific experiment.

+
+This vignette describes the intended workflow and usage of the wilson package for building an application and provides a simple example.
+
+**Prerequisites:**
+
+* be familiar with the basic structure of a [shiny-app](https://shiny.rstudio.com/articles/basics.html) and [shinydashboard](https://rstudio.github.io/shinydashboard/get_started.html)
+* know how to use [shiny-modules](https://shiny.rstudio.com/articles/modules.html#using-modules)
+* have a sufficient dataset in clarion-format
+  * either by [converting](https://github.molgen.mpg.de/loosolab/wilson-apps/wiki/CLARION-Format/) your own data
+  * or downloading from [here](https://github.molgen.mpg.de/loosolab/wilson-apps/tree/master/wilson-basic/data/)
+
+## Workflow
+
+The workflow of a wilson-application can roughly be divided into three basic steps:
+
+1. load data
+2. filter data
+3. visualize data
+
+But depending on the actual implementation neither the order nor the number of steps are set. Resulting in enhanced usability as for example the filter can be changed at any given time.
+
+## Example
+
+In this example we will create a wilson-application with a static dataset, a single visualization method and a preceding filter, seperated into a *Filter* and a *Visualization* tab.
+
+So to start we first import the needed packages and afterwards define the application interface:
+```
+library(shiny)
+library(shinydashboard)
+library(wilson)
+
+# Define UI for application
+ui <- dashboardPage(
+    header = dashboardHeader(disable = TRUE),
+    sidebar = dashboardSidebar(disable = TRUE),
+    body = dashboardBody(
+        tags$style(type = "text/css", "body {padding-top: 50px;}"),
+        navbarPage(
+            title = "wilson example",
+            position = "fixed-top",
+            tabPanel(title = "Filter",
+                     # Load filter UI
+                     featureSelectorUI(id = "filter")),
+            tabPanel(title = "Visualization",
+                     # Load scatterplot UI
+                     scatterPlotUI(id = "scatter"))
+        )))
+```
+This code creates an UI with two tabs. The first tab with the title *Filter* contains the filter UI called with `featureSelectorUI()` whereas the UI needed for a scatterplot called with `scatterPlotUI()` is enclosed by the second tab (*Visualization*).
+
+Second the server function needs to be as follows:
+```
+# Define server logic required for filtering and plotting
+server <- function(input, output, session) {
+    # load/ parse data
+    # change this path to match your file location
+    data <- parser("../wilson-apps/wilson-basic/data/A_RNAseq_Zhang_2015.se")
+    
+    # Load filter server logic
+    filtered_data <- callModule(module = featureSelector, id = "filter", clarion = data)
+    # Load scatterplot server logic
+    callModule(module = scatterPlot, id = "scatter", clarion = reactive(filtered_data()$object))
+}
+
+# Run the application 
+shinyApp(ui = ui, server = server)
+```
+The server reacts to user interactions whith the interface. Once started it will first parse the given [clarion](https://github.molgen.mpg.de/loosolab/wilson-apps/wiki/CLARION-Format/) file into a clarion object, performing validation steps in the process. Next the server functions of the necessary [modules](https://shiny.rstudio.com/articles/modules.html) defined in the UI (notice the matching ids) are loaded. Whereas the filter module bluntly accepts the data object with `clarion = data` the plot module receives its data via `clarion = reactive(filtered_data()$object)`. Wrapping in `reactive()` is due to the fact, that the filtered data object returned from the filter module is in a reactive context which essentially means shiny 'knows' when this variable changes. Read more about shiny's reactivity system [here](https://shiny.rstudio.com/articles/reactivity-overview.html).
