Comments
From now on the Rfast can be used in C++ via "LinkingTo" mechanism.
The main namespace is "Rfast". Inside "Rfast" you will find two more namespaces, "vector" and "matrix".
Namespace "vector" for calling functions using an Rcpp's or RcppArmadillo's vector.
Namespace "matrix" for calling functions using an Rcpp's or RcppArmadillo's matrices.
The signatures of the functions and the arguments are the same that are exported in R.
For namespace "vector" the functions that are available are
- median(x)
- var(x, std = false, na_rm = false)
- mad(x, method = "median", na_rm = false)
- shuffle(x,engine = Engine(time(0)) // Engine by default is default_random_engine. You can use anyone from C++.
For namespace "matrix" the functions that are available are
- transpose(x)
- matrix_multiplication(x,y)
- colSort(x, descend = false, stable = false, parallel = false)
- rowSort(x, descend = false, stable = false, parallel = false)
- is_symmetric(x)
- colMedian(x, na_rm = false, parallel = false)
- rowMedian(x, na_rm = false, parallel = false)
- colVars(x, std = false, na_rm = false, parallel = false)
- rowVars(x, std = false, na_rm = false, parallel = false)
- colMads(x, method = "median", na_rm = false, parallel = false)
- rowMads(x, method = "median", na_rm = false, parallel = false)
- colShuffle(x,engine = Engine(time(0)) // Engine by default is default_random_engine. You can use anyone from C++.
- rowShuffle(x,engine = Engine(time(0)) // Engine by default is default_random_engine. You can use anyone from C++.
How to use it
- Just add in "LinkingTo" in your NAMESPACE file the "Rfast" or in Rstudio add in the file "//[[Rcppdepends(Rfast)]]".
Include in your cpp files the header "Rfast.h" and enjoy!
