argo_traj: Load Argo trajectories

In ArgoCanada/argodata: Locate, Download, and Read Argo Ocean Float Data

Description

Use argo_traj_*() functions to extract information from Argo trajectory NetCDF files. Use argo_read_traj_*() to extract information from a single previously-downloaded NetCDF file.

Usage

argo_traj_measurement(path, vars = NULL, download = NULL, quiet = NA)

argo_traj_cycle(path, vars = NULL, download = NULL, quiet = NA)

argo_traj_param(path, vars = NULL, download = NULL, quiet = NA)

argo_traj_history(path, vars = NULL, download = NULL, quiet = NA)

Arguments

path	A path relative to the root directory of argo_mirror() or argo_cache_dir(). This value can also be a data.frame with a file column (e.g., a global index as returned by argo_global_meta() and others).
vars	A vector of variable names to include. Explicitly specifying vars can lead to much faster read times when reading many files.
download	A logical vector indicating whether or not a file should be downloaded. Defaults to the value of argo_should_download(), which is TRUE for files that do not exist in the cache.
quiet	Use FALSE to show which files are downloaded and for more verbose error messages.

Value

A tibble::tibble() with

• argo_traj_measurement(): one row per file per measurement.

• argo_traj_cycle(): one row per file per cycle.

• argo_traj_param(): one row per file per parameter.

• argo_traj_history(): one row per file per history entry.

Examples

with_argo_example_cache({
  argo_traj_measurement("dac/csio/2900313/2900313_Rtraj.nc")
})

with_argo_example_cache({
  argo_traj_cycle("dac/csio/2900313/2900313_Rtraj.nc")
})

with_argo_example_cache({
  argo_traj_param("dac/csio/2900313/2900313_Rtraj.nc")
})

with_argo_example_cache({
  argo_traj_history("dac/csio/2900313/2900313_Rtraj.nc")
})
