cecs's Issues

CEC2005

Due to low quality of implementation, CEC2005 is not included in the package.

It's source code in C has to be rewritten.

Malloc.h on macOS

cec2013 uses malloc.h header which has been superseded and is not included in macOS.

Error message:

clang -mmacosx-version-min=10.13 -I"/Library/Frameworks/R.framework/Resources/include" -DNDEBUG   -I/usr/local/include   -fPIC  -Wall -g -O2  -c cec2013.c -o cec2013.o

Correct before 2021-02-01 to retain package on CRAN.

Remove note from CRAN check

Note:

Version: 0.1.0 
Check: compiled code 
Result: NOTE 
    File ‘cecs/libs/cecs.so’:
     Found no calls to: ‘R_registerRoutines’, ‘R_useDynamicSymbols’

Performance issues

Code execution is sluggish (even 5 times slower than code from {cec2013} or {cec2017}) due to stringr::str_interp() function and/or bad C code organization.

  • replace stringr::str_interp with base::paste0
  • re-organize C code
