Rigraphlib 1.0.0
Rigraphlib builds the igraph static library for use in R/Bioconductor packages. This is primarily intended for R packages that wrap other C/C++ libraries that depend on the igraph C library and cannot easily be modified to use the usual igraph R package. By vendoring in the source code, we also reduce our susceptibility to out-of-release-schedule changes in results due to igraph updates. This also allows developers to access functionality that might yet not be available from the R bindings.
Currently, this package contains version 0.10.15 of the C igraph library.
Downstream package developers can use Rigraphlib by adding:
Imports: Rigraphlib
to their package DESCRIPTION
, and setting:
RIGRAPH_FLAGS=$(shell "${R_HOME}/bin${R_ARCH_BIN}/Rscript" -e 'Rigraphlib::pkgconfig("PKG_CPPFLAGS")')
PKG_CPPFLAGS=$(RIGRAPH_FLAGS)
RIGRAPH_LIBS=$(shell "${R_HOME}/bin${R_ARCH_BIN}/Rscript" -e 'Rigraphlib::pkgconfig("PKG_LIBS")')
PKG_LIBS=$(RIGRAPH_LIBS) $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)
in their src/Makevars
.
We use R’s own BLAS and LAPACK libraries to avoid redundant recompilation of igraph’s vendored copies.
