This function list the file names, types, upload date, and URLs of OTN data extraction files -- basically everything you see in the Data Extraction Files section of your project page. Because it is from your project page, you will be prompted to log in.
Usage
list_extract_files(
project,
detection_type = c("all", "matched", "external", "qualified", "sentinel",
"unqualified"),
since = NULL
)Arguments
- project
Either the project code, the project number (the number in your project page URL), or the full name of the project (the big name in bold on your project page, not the "Project Title").
- detection_type
one of, or a vector of, "all" (default), "matched", "external", "qualified", "sentinel_tag", or "unqualified". Partial matching is allowed, and will repair to the correct argument if spaces or the words detection(s)" are included. More information on data types can be found on OTN's website.
- since
Only list files uploaded after this date. Optional, but must be in YYYY-MM-DD format.
Value
A data frame with columns of "project", "file_type", "detection_type", 'detection_year', 'upload_date', 'file_name', and "url".
Details
list_extract_files is a wrapper around a web-scraping routine:
find the project number if not provided, 2) download the HTML table, 3) parse the URL for each file, and 4) combine the table and URLs into a data frame. This function is most useful when investigating what files you have available, and then downloading them with
get_extract_file.
list_extract_files lists files associated with the ACT_MATOS OTN node. These
are files listed on the Data Extraction Files page.
Examples
if (FALSE) { # all(skip_example_on_cran(), skip_example_on_runiverse())
# List all extraction files using project number
list_extract_files(87)
# Or, just grab the matched receiver detections
list_extract_files(project = 87, detection_type = "qualified")
# OR list files using the project name
list_extract_files("umces boem offshore wind energy")
}
