metrica 2.0.4

This version: 1) fixes an issue found for Debian for Importing APSIM NewGeneration files that violated CRAN Policy’s.

  1. adds a new classification metric called P4, following Sitarz, M. (2023) doi:10.54364/AAIML.2023.1161. https://github.com/adriancorrendo/metrica/issues/36 Special thanks to Davide Chicco for suggesting this metric.

  2. fixes an error in the invF05 formula from the adjusted F-score metric (agf):

  1. adds a new plot argument, shape_fill, indicating the shape fill for the data points on the ‘scatter_plot’ and ‘bland_altman_plot’ functions.

metrica 2.0.3

CRAN release: 2023-04-14

This version fixes an issue found for Debian for Importing APSIM NewGeneration files that violated CRAN Policy’s.

Change details:

  1. Adding a READ-ONLY flag within import_apsim_db() as follows:

con <- DBI::dbConnect(…, flags = RSQLite::SQLITE_RO)

  1. Simplified vignette for open “APSIM: Importing APSIM Classic and NewGeneration files” now implementing “eval = FALSE” for a chunk containing example code to open APSIM files. Code is there but not running by default.

Potentially problematic code line: apsim_out_filepath <- system.file(“extdata/soybean.out”, package = “metrica”)

metrica 2.0.2

CRAN release: 2023-04-02

This new version fixes minor bugs from version 2.0.1, typos, update and add new vignettes, and add alternative functions to several classification performance metrics. Details:

This new development version fixes minor bugs found in v2.0.1:

  1. Adding “Contributing”” and “Code of conduct”” sections to the README file.

  2. Adding “CODE_OF_CONDUCT.md” file.

  3. Adding a list of abbreviations used on the vignette “Available Classification Metrics”.

  4. Fixing a bug on the PLA and PLP formulas, which were not working when the data argument was specified.

  5. Corrects, on the DESCRIPTION file, the minimum R version required (from 2.1.0 to 3.6.2)

  6. Including an “extdata” directory containing APSIM example files (soybean.out & soybean.example.db)

  7. Fix typos in the documentation of RRMSE, RSR, and iqRMSE, which formulas were corrected (removing 100 from the beginning of formulas.

  8. Add alternative functions to recall performing identical job such as (i) sensitivity, (ii) True Positive Rate -TPR-, and (iii) Hit Rate -hitrate-.

  9. Add alternative functions to specificity performing identical job such as (i) selectivity, (ii) True Negative Rate -TNR-.

  10. Add vignettes related to (i) publication of metrica on the Journal of Open Source Software (JOSS), (ii) the metrica ShinyApp, and (iii) the new cheatsheets of the metrica package.

  11. Make a correction on the vignette specifying the formula of Duveiller’s lambda(), which by the way does not affect the lambda() function itself.

  12. Add alternative functions to precision (ppv()), mcc (phi_coef()), bmi (jindex()), csi (jaccardindex()), and deltap (mk()).

  13. Add CITATION file into “inst/” folder following bibentry format.

metrica 2.0.1

CRAN release: 2022-07-24

  • July 23th, 2022.

This new version fixes minor bugs found in v2.0.0:

  1. regression lines with “OP” orientation in scatter_plot(), density_plot(), and tiles_plot(), which were producing the “PO” oriented regression lines instead.

  2. estimation of “d1r” index for regression, which produced misleading values due to a typo in the denominator.

  3. printing metrics on confusion matrix, which produced a NaN when printing 9 metrics.

  • preval_t(): Prevalence threshold.
  • AUC_roc(): Area Under the ROC Curve (trapezoid approach).
  1. Three (3) additional functions to the family of regression performance metrics:
  1. Update of the metrics_summary() function including:
  • run performance metrics summary either for “regression” or “classification” using the new type argument, ‘required’ to specify the type of prediction task.
  • pos_level argument, for binomial classification, to allow the user to specify the alphanumeric order of the “positive” level.
  1. One (1) additional plotting function for regression:
  • density_plot(), to create a plot that paints density areas of predicted and observed coordinates.

  1. Fixing issue with the tiles_plot() not plotting hexagons. Changed ggplot2::geom_hex() by ggplot2::stat_bin2d

  3. Improved coverage of the code testing.

  4. README update with new features descriptions and links to vignettes.

  5. Updated vignettes creating independent versions for classification and regression models, and for importing APSIM files.

metrica 1.2.3

CRAN release: 2022-05-12

  • May, 10, 2022.

Maintenance update fixing minor errors after feedback from CRAN submission of v1.2.2 (e.g. use ‘donttest’ instead of ‘dontrun’ in functions’ examples, adding references into functions). Also, the available metrics vignette was updated adding the corresponding citations of formulae used into functions.

metrica 1.2.2

  • May, 05, 2022.

Maintenance update fixing minor bugs related to checks before CRAN submission (e.g. spelling check, URLs, DOIs, etc.)

metrica 1.2.1

Minor updates (1.2.1):

Update of function and arguments’ names replacing “.” by “_“:

Old | New import.apsim.out | import_apsim_out import.apsim.db | import_apsim_db metrics.summary | metrics_summary scatter.plot | scatter_plot tiles.plot | tiles_plot bland.altman.plot | bland_altman_plot B0.sma | B0_sma B1.sma | B1_sma metrics.list | metrics_list print.metrics | print_metrics

New features (1.2.0)

Data: a new (Optional) arg. called “data” is included for all functions, which serves to call an existing data frame containing the predicted-observed data. This facilitates passing the functions to multiple and nested data frames at once using mapping functions.

APSIM: includes two new functions to read APSIM output files from APSIM Classic [“*.out”, import.apsim.out()] and APSIM NextGen [“*.db”, import.apsim.db()].
