RJafroc

Build Status codecov CRAN_Status_Badge

What is this repository for?

  • Modeling, Analysis, Validation and Visualization of ROC/FROC studies
  • Extends and replaces the obsolete Windows software (JAFROC: http://www.devchakraborty.com)

Documentation (vignettes) available at https://dpc10ster.github.io/RJafroc/

My wiki is at https://github.com/dpc10ster/RJafroc/wiki

A CRAN version of RJafroc is in preparation

Thanks to help from Dr. Peter Phillips, a version of RJafroc that should pass CRAN tests is close to completion. As usual, the most current version of the software is available right here.

Those already familiar with installing R packages from GitHub can ignore the following directions

How do I get set up?

Short version: install directly from GitHub using package devtools

  • Install R and RStudio.
  • Create an empty directory, e.g., myProject. In my computer it is /Users/Dev/Downloads/myProject.
  • Open RStudio.
  • Starting from RStudio > File > New Project > Existing Directory > Select myProject > Create Project.
  • Oila! You should see myProject.RProj in the Files menu.
  • Install the devtools package as shown below:
  • Starting from RStudio > Packages > Install > devtools.
  • Load devtools as shown below:
library(devtools)
  • Install RJafroc directly from GitHub (this is where devtools is used):
install_github("dpc10ster/rjafroc")
  • Hit Enter on any prompts...
  • Lots of activity and compilation of C++ code ....
  • Load RJafroc as shown below:
library(RJafroc)
  • Test the installation:
cbmPlot <- PlotCbmFit(c(1, 2), c(0.5, 0.5))
print(cbmPlot)
  • You should see two ROC plots in the Plots window.
  • Preliminary documentation (vignettes) is available at https://dpc10ster.github.io/RJafroc/.
  • Be sure to study these examples and make full use of the online documentation.
  • Put your data and other files, if any, in myProject.
  • TBA

Long version: download the RJafroc package and install from the downloaded files

  • Clone this repository to a directory anywhere on your computer. On my computer it is in /Users/Dev/Downloads/rjafroc. Rename the folder if necessary to match my example.
  • I find the GitHub desktop app useful in mananging my downloads/uploads from Git.
  • Install R and RStudio.
  • Navigate to the rjafroc directory.
  • Open RJafroc.Rproj. This will open RStudio.
  • Navigate to File menu (lower-right window) and click on DESCRIPTION file.
  • Install all packages listed under Imports, e.g.,
    openxlsx, ggplot2, stringr, tools, utils, stats, bbmle, binom, mvtnorm, dplyr, numDeriv, Rcpp
  • For example, to install the first two above-listed packages, use the following command at the Console prompt:
install.packages(c("openxlsx", "ggplot2"))
  • Click on Build > Install and Restart (upper right panel). If errors result from missing packages, install those packages.
  • A successful Install and Restart will result in the following line in the Console window:
library(RJafroc)
  • Thats it! RJafroc has been installed to your computer and is visible to any other R project in any directory.
  • You will not need to access the RJafroc folder again (unless you reinstall a new version of the software).
  • All necessary files of the installation are in a hidden directory that you do not normally need to worry about.
  • Create an empty directory, e.g., myProject. In my computer it is /Users/Dev/Downloads/myProject.
  • Starting from RStudio > File > New Project > Existing Directory > myProject > Create Project.
  • Oila! You should see myProject.RProj in the Files menu.
  • Click on Packages and scroll down to find RJafroc, and check the box next to it. This results in RJafroc being loaded to the current workspace. The following line appears in the Console window (this is the hidden directory referrred to above).
  library("RJafroc", lib.loc="/Library/Frameworks/R.framework/Versions/3.5/Resources/library")
  • Click on RJafroc in the packages window. A help window opens up. I find it convenient to put this in its own window by clicking the "out" arrow button (hover message: Show in new window). You can access all documentation from here.
  • Test the installation:
cbmPlot <- PlotCbmFit(c(1, 2), c(0.5, 0.5))
print(cbmPlot)
  • You should see two ROC plots in the Plots window.
  • Preliminary documentation (vignettes) is available at https://dpc10ster.github.io/RJafroc/.
  • Put your data and other files, if any, in myProject.
