ITKR 用于lesymap安装

# ITKR <!-- badges: start --> [](https://github.com/stnava/ITKR/actions) [](https://travis-ci.org/stnava/ITKR) muschellij2 badge: [](https://travis-ci.org/muschellij2/ITKR) <!-- badges: end --> ITK*R* provides *R*-based access to the [Insight ToolKit (ITK)](http://www.itk.org) for medical image processing, registration and segmentation. ITK*R* installs this library in *R* style and provides user or developer access to its templated header files and libraries. Consequently, this is a core package on which it is expected that other packages will build functionality. Shout out to Bartlett Bears. Basic documentation is here [https://stnava.github.io/ITKR/](https://stnava.github.io/ITKR/). One such package is [ANTsR](https://github.com/stnava/ANTsR). A developer should be able to use this package as a guide for how they might wrap ITK themselves, within *R*. Primarily, one uses ITK*R* to manage the compilation of the dependent software's knowledge of ITK resources. To install ITKR: ``` devtools::install_github( "stnava/ITKR" ) ``` The primary result of this installation process is *R*-based access to the ITK library. The user or developer can identify the location of the ITK installation by performing: ``` ITKR::itkIncludes() ``` which uses `cat` to report the install location. We use `cat` because it allows the developer simpler access to these variable names in Makefiles and other compilation-related scripts. If you want to store the variable within R: ``` itkinstalldir <- capture.output( ITKR::itkIncludes() ) ``` This package is still an early development version.
