Quick start

SPS example usage

To start with SPS after installation:

Load package

Load the systemPipeShiny package in your R session.

## Loading required package: shiny
## Loading required package: spsUtil
## Loading required package: spsComps
## Loading required package: drawer

Initialize SPS project

Before launching the SPS application, a project environment needs to be created with the following command.


For this demo, the project directory structure is written to a temporary directory on a user’s system. For a real project, it should be written to a defined and user controlled location on a system rather than a temporary directory.

sps_tmp_dir <- tempdir()
spsInit(app_path = sps_tmp_dir, change_wd = FALSE, project_name = "SPSProject")

sps_dir <- file.path(sps_tmp_dir, "SPSProject")

SPS project structure

The file and directory structure of an SPS project is organized as follows.

├── server.R               |

Launch SPS

By default, the working directory will be set inside the project folder automatically. To launch the SPS Shiny application, one only needs to execute the following command.


After the SPS app has been launched, clicking the “Continue to app” button on the welcome screen will open the main dashboard (Fig.2).


Figure 2: Snapshot of SPS' UI.

  1. Welcome screen.
  2. Module tabs.
  3. User defined custom tabs.
  4. The Canvas tab.
  5. All SPS tabs has this description on top. It is highly recommend to click here to expand and read the full the description for the first time.

Alternatively, when using RStudio one can click the Run App button in the top right corner.

In addition, in Rstudio the global.R file will be automatically opened when the SPS project is created. Custom changes can be made inside this file before the app launches. Later we will discuss how to change and create new custom tabs and change other settings.
