merge_camtrapdp: Merge two Camera Trap Data Packages

In inbo/camtrapdp: Read and Manipulate Camera Trap Data Packages

Merge two Camera Trap Data Packages

Description

Merges two Camera Trap Data Package objects into one.

Usage

merge_camtrapdp(x, y)

Arguments

x, y	Camera Trap Data Package objects, as returned by read_camtrapdp().

Value

A single Camera Trap Data Package object that is the combination of x and y.

Transformation details

Both x and y must have a unique dataset name x$name and y$name. This name is used to prefix identifiers in the data that occur in both datasets. For example:

• x contains deploymentIDs c("a", "b").

• y contains deploymentIDs c("b", "c").

• Then merged xy will contain deploymentIDs c("a", "x_b", "y_b", "c").

Data are merged as follows:

• Deployments are combined, with deploymentID kept unique.

• Media are combined, with mediaID, deploymentID and eventID kept unique.

• Observations are combined, with observationID, deploymentID, mediaID and eventID kept unique.

• Additional resources are retained, with the resource name kept unique.

Metadata properties are merged as follows:

• name: Removed.

• id: Removed.

• created: Set to current timestamp.

• title: Removed.

• contributors: Combined, with duplicates removed.

• description: Combined as two paragraphs.

• version: Set to 1.0.

• keywords: Combined, with duplicates removed.

• image: Removed.

• homepage: Removed.

• sources: Combined, with duplicates removed.

• licenses: Combined, with duplicates removed.

• bibliographicCitation: Removed.

• project$id: Removed.

• project$title: Combined.

• project$acronym: Removed.

• project$description: Combined as two paragraphs.

• project$path: Removed.

• project$samplingDesign: Sampling design of x.

• project$captureMethod: Combined, with duplicates removed.

• project$individuals: TRUE if one of the datasets has TRUE.

• project$observationLevel: Combined, with duplicates removed.

• coordinatePrecision: Set to the least precise coordinatePrecision.

• spatial: Reset based on the new deployments.

• temporal: Reset based on the new deployments.

• taxonomic: Combined, with duplicates removed.

• relatedIdentifiers: Combined, with duplicates removed.

• references: Combined, with duplicates removed.

• Custom properties of x are also retained.
