This function creates customized Shiny App with user-provided data, aSVG files, and default parameters. Default settings are defined in the "config.yaml" file in the "config" folder of the app, and can be edited directly in a yaml file editor.

Separate lists of paired data matrix and aSVG files, which are included as default datasets in the Shiny app. Each list must have three elements with name slots of "name", "data", and "svg" respectively. For example, list(name='dataset1', data='./data1.txt', svg='./root_shm.svg'). The "name" element (e.g. 'dataset1') is listed under "Step 1: data sets" in the app, while "data" and "svg" are the paths of data matrix and aSVG files. If multiple aSVGs (e.g. growth stages) are included in one list, the respective paths are stored in a vector in the "svg" slot (see example below). After calling this function, the data and aSVGs are copied to the "example" folder in the app. See detailed examples below. |
lis.par |
A list of default parameters of the Shiny app. See |
lis.par.tmp |
Logical, TRUE or FALSE. Default is FALSE. If TRUE the template of default paramter list is returned, and users can set customized default values then assign this list to |
lis.dld.single |
A list of paired data matrix and single aSVG file, which would be downloadable on the app for testing. The list should have two elements with name slots of "data" and "svg" respectively, which are the paths of the data matrix and aSVG file repectively. After the function call, the specified data and aSVG are copied to the "example" folder in the app. Note the two name slots should not be changed. E.g. |
lis.dld.mul |
A list of paired data matrix and multiple aSVG files, which would be downloadable on the app for testing. The multiple aSVG files could be multiple growth stages of a plant. The list should have two elements with name slots of "data" and "svg" respectively, which are the paths of the data matrix and aSVG files repectively. After the function call, the specified data and aSVGs are copied to the "example" folder in the app. Note the two name slots should not be changed. E.g. list(data='./data_download.txt', svg=c('./root_young_download_shm.svg', './root_old_download_shm.svg')). |
custom |
Logical, TRUE or FALSE. If TRUE (default), the "customData" option under "Step 1: data sets" is included, which allows to upload datasets from local computer. |
custom.computed |
Logical, TRUE or FALSE. If TRUE (default), the "customComputdData" option under "Step 1: data sets" is included, which allows to upload computed datasets from local computer. See |
example |
Logical, TRUE or FALSE. If TRUE, the default examples in "spatialHeatmap" package are included in the app as well as those provided to |
app.dir |
The directory to create the Shiny app. Default is current work directory |
If lis.par.tmp==TRUE
, the template of default paramter list is returned. Otherwise, a customized Shiny app is generated in the path of app.dir
.
