pd_get_md {prism}

Get prism metadata

Description

Retrieves prism metadata from the specified prism data. "prism data", i.e., pd are the folder names returned by prism_archive_ls() or prism_archive_subset(). These functions get the name or date from these data, or convert these data to a file name. A warning is provided if the specified prism data do not exist in the archive.

Usage

pd_get_md(pd)

Arguments

pd

prism data character vector.

Details

The metadata includes the following variables from the .info.txt file for daily, monthly, and annual data:

• PRISM_DATASET_FILENAME

• PRISM_DATASET_CREATE_DATE

• PRISM_DATASET_TYPE

• PRISM_DATASET_VERSION

• PRISM_CODE_VERSION

• PRISM_DATASET_REMARKS

Additionally, two local variables are added identifying where the file is located on the local system:

• file_path

• folder_path

The annual and monthly normals data includes different keys in the .info.txt, so they are renamed to be the same as those found in the other temporal data. The keys/variables are renamed as follows:

• PRISM_FILENAME –> PRISM_DATASET_FILENAME

• PRISM_CREATE_DATE –> PRISM_DATASET_CREATE_DATE

• PRISM_DATASET –> PRISM_DATASET_TYPE

• PRISM_VERSION –> PRISM_CODE_VERSION

• PRISM_REMARKS –> PRISM_DATASET_REMARKS

Additionally, the normals does not include PRISM_DATASET_VERSION, so that variable is added with NA values.

Value

data.frame containing metadata for all specified prism data.
