Package to generate (generalized) calibration curves and related statistics. The function for the logistic/flexible calibration curves are based on the val.prob function from Frank Harrellâs rms package.
Installation On current R (>= 3.0.0)library("devtools")
install_github("BavoDC/CalibrationCurves", dependencies = TRUE, build_vignettes = TRUE)(This requires devtools >= 1.6.1, and installs the âmasterâ (development) branch.) This approach builds the package from source, i.e. make and compilers must be installed on your system â see the R FAQ for your operating system; you may also need to install dependencies manually.
The basic functionality of the package is explained and demonstrated in the vignette, which you can access using
vignette("CalibrationCurves")or via the homepage of the package.
