This reproducible R Markdown analysis was created with workflowr (version 1.7.0). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.
Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.
Great job! The global environment was empty. Objects defined in the global environment can affect the analysis in your R Markdown file in unknown ways. For reproduciblity it’s best to always run the code in an empty environment.
The command set.seed(20211008) was run prior to running
the code in the R Markdown file. Setting a seed ensures that any results
that rely on randomness, e.g. subsampling or permutations, are
reproducible.
Great job! Recording the operating system, R version, and package versions is critical for reproducibility.
Nice! There were no cached chunks for this analysis, so you can be confident that you successfully produced the results during this run.
Great job! Using relative paths to the files within your workflowr project makes it easier to run your code on other machines.
Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility.
The results in this page were generated with repository version f37a13f. See the Past versions tab to see a history of the changes made to the R Markdown and HTML files.
Note that you need to be careful to ensure that all relevant files for
the analysis have been committed to Git prior to generating the results
(you can use wflow_publish or
wflow_git_commit). workflowr only checks the R Markdown
file, but you know if there are other scripts or data files that it
depends on. Below is the status of the Git repository when the results
were generated:
Ignored files:
Ignored: .Rproj.user/
Ignored: analysis/load_argo_clim_temp_csio.html
Untracked files:
Untracked: analysis/draft.Rmd
Unstaged changes:
Modified: analysis/_site.yml
Modified: analysis/child/cluster_analysis_base.Rmd

Modified: code/Workflowr_project_managment.R
Modified: code/start_background_job.R
Modified: code/start_background_job_load.R
Modified: code/start_background_job_partial.R
Note that any generated files, e.g. HTML, png, CSS, etc., are not included in this status report because it is ok for generated content to have uncommitted changes.
These are the previous versions of the repository in which changes were
made to the R Markdown (analysis/load_argo_core.Rmd) and
HTML (docs/load_argo_core.html) files. If you’ve configured
a remote Git repository (see ?wflow_git_remote), click on
the hyperlinks in the table below to view the files as they were in that
past version.

Task
Makes use of argodata libraries to load argo profile related data, stages load index, data and metadata files. Cache files (saved in /nfs/kryo/work/datasets/ungridded/3d/ocean/floats/core_argo_r_argodata and dac subdirectory) are used, set option opt_refresh_cache to TRUE to force a refresh – This process takes considerable time.
The load process described in this paragraph is carried out for each year and the files are saved to the core preprocessed. core_index data frame is created based on delayed mode files and a supplied date range. The index file is then used to load profile data into core_data and associated meta data into core_metadata. core_data is segregated into core_data_temp and core_data_psal. core_data_temp, core_data_psal and core_metadata are filtered by n_prof == opt_n_prof_sel. Description of n_prof usage is provided at https://argo.ucsd.edu/data/data-faq/version-3-profile-files/ the following is from that page. The main Argo CTD profile is stored in N_PROF=1. All other parameters (including biogeochemical parameters) that are measured with the same vertical sampling scheme and at the same location and time as the main Argo CTD profile are also stored in N_PROF=1.
On completion combined all year core_data_temp, core_data_psal and core_metadata that incorporate all years. core_data_temp, core_data_psal and core_metadata initially contain a string field file that uniquely identifies the profile and links the two data frames. An additional data from core_fileid is created with a unique list file fields along with a numeric file_id field. The file fields in core_data and core_metadata are then replaced with file_id.
core_temp_flag_A and core_temp_flag_AB are created that support prior analysis. In addition, a data frame core_measure_summary is created that is used for load level reporting figures.
Files are written to the core preprocessed folder for ongoing analysis.
Dependencies
Cache files - /nfs/kryo/work/datasets/ungridded/3d/ocean/floats/core_argo_r_argodata_2024-03-13
Outputs (in core preprocessed folder)
core_index.rds – Copy of the index file that was used in the selection of data and meta data files.
core_data_temp.rds – The main core temperature profile data.
core_data_psal.rds – The main core salinity profile data.
core_metadata.rds – The associated meta data information.
core_fileid.rds – A lookup from file_id to file.
Each of the below files are used in prior analysis and maintained to support that analysis.
core_temp_flag_A.rds
core_temp_flag_AB.rds
