fhir_style: Create fhir_style object

Description

This function creates an object of class fhir_style. It contains the three elements sep, brackets and rm_empty_cols. See Details.

Usage

fhir_style(sep = " ", brackets = character(), rm_empty_cols = FALSE)

Arguments

sep

A character vector of length one to separate pasted multiple entries. Defaults to " "

brackets

A character vector of length two defining the brackets surrounding indices for multiple entries, e.g. c( "<", ">"). If this is empty (i.e. character of length zero, the default) or 'NULL', no indices will be added to multiple entries. If it is a character vector of length one, it will be recycled to length two, i.e. "|" will become c("|", "|"). Empty strings ("") are not allowed.

rm_empty_cols

A logical vector of length one. Remove empty columns? Defaults to FALSE.

Value

A fhir_style object

Details

A fhir_style object is part of a '>fhir_table_description which in turn is part of a '>fhir_design and ultimately used in fhir_crack(). A fhir_style object contains three elements:

• sep: A string defining the separator used to separate multiple entries for the same element in a FHIR resource, e.g. multiple address/city elements in a Patient resource.

• brackets: A character vector of length two defining the brackets surrounding indices for multiple entries, e.g. c( "<", ">"). If this is empty (i.e. character of length 0, the default), no indices will be added to multiple entries. Empty strings ("") are not allowed.

• rm_empty_cols: A logical scalar defining whether or not to remove empty columns after cracking. Empty columns arise when you try to extract an element that doesn't appear in any of the resources. A fhir_style object looks for example like this:

sep: ' '
brackets: '[' ']'
rm_empty_cols: FALSE

Examples

# NOT RUN {
fhir_style(sep = " ",
           brackets = c("[", "]"),
           rm_empty_cols = TRUE)

# }
