Create/Edit EML attributes

Source: R/shiny_attributes.R
shiny_attributes.Rd

Create/edit EML attributes, custom units, and factors in a shiny environment.

Usage

shiny_attributes(data = NULL, attributes = NULL)

Arguments

data

(data.frame) the data.frame of data that needs an attribute table

attributes

(data.frame) an existing attributes table

Details

Attributes can be created from scratch using shiny_attributes(). Or an existing attribute table can be edited using shiny_attributes(NULL, attributes). Or new attributes can be created from a data table using shiny_attributes(data, NULL). If attributes are created from a data table, fields such as `attributeName` and `numberType` will be automatically completed based on the attributes within the data table. If both existing attributes and data table are entered (i.e. shiny_attributes(data, attributes)), any automatically generated fields based attributes within the data table **will not** override any non-empty fields in the entered attributes

Examples

if (FALSE) {
# from scratch
out <- shiny_attributes(NULL, NULL)

# from data
data <- iris
out <- shiny_attributes(data, NULL)

# from exisiting attributes
file <- system.file("tests", emld::eml_version(),
  "eml-datasetWithAttributelevelMethods.xml",
  package = "emld"
)
eml <- read_eml(file)
x <- eml$dataset$dataTable$attributeList
df <- get_attributes(x, eml)
out <- shiny_attributes(NULL, df$attributes)

# from attributes and data
out <- shiny_attributes(data, df$attributes)
}
