General information
stringi is an R package for fast, portable, correct, consistent, and convenient string/text processing in any locale or character encoding.
Installation
Please enter the code, presented in the boxes below, directly in your shell/command line on bwUniCluster:
Preparations
Prepare an .R/Makevars file (if it does not already exist). This file specifies how R should compile the packages (i.e., sets some 'compiler flags').
If an .R/Makevars file is present in your home directory ($HOME), check whether the flags displayed below are set and apply adjustments, if necessary:
cat ~/.R/Makevars CXX14=g++ CXX17=g++ CXXFLAGS = -O3 -fPIC -mavx -mavx2 -mavx512f -msse4.2 -ffp-contract=off -fno-fast-math -fno-signed-zeros -fopenmp -Wno-unknown-warning-option CXX14FLAGS += -std=c++14 CXX17FLAGS += -std=c++17
Please run the following lines of code to set the appropriate flags, if necessary:
mkdir -p ~/.R echo "CXX14=g++" > ~/.R/Makevars echo "CXX17=g++" >> ~/.R/Makevars echo "CXXFLAGS = -O3 -fPIC -mavx -mavx2 -mavx512f -msse4.2 -ffp-contract=off -fno-fast-math -fno-signed-zeros -fopenmp -Wno-unknown-warning-option" >> ~/.R/Makevars echo "CXX14FLAGS += -std=c++14" >> ~/.R/Makevars echo "CXX17FLAGS += -std=c++17" >> ~/.R/Makevars
Install the R package
We can now install stringi and its dependencies within a R session. To get the most out of stringi, you are strongly encouraged to rely on the custom ICU4C 74.1 implementation bundled with stringi:
module purge
module load math/R/4.4.1-mkl-2022.2.1-gnu-13.3
R -q
R> install.packages("stringi", configure.args="--disable-pkg-config")
This ensures maximum portability across all platforms (Windows and macOS users fetch the pre-compiled binaries from CRAN built precisely this way).
Testing the installation
To check whether the installation worked, make a test run in R
> library(stringi)
> stri_length(c("Hello", "world", "!"))
