R – free Statistics Package for Delphi

delphirsasstatistics

Is there an open source and/or free statistics package or library for Delphi? I'm looking for something that can compile directly into the executable, so no DLL's. It needs to be compatible with Delphi 2009 and later (the Unicode versions).

Hopefully there is something comprehensive available out there. By comparison, I am used to the amazing features of SAS and R.

I'm looking for distribution functions (normal, binomial, chi square, logit) and regression (linear, non-linear, multinomial) and if possible predictors (e.g. ARIMA).

There's a large but somewhat out of date list here. I've never seen anything as comprehensive as SAS or R, however. Then again, SAS and R are more comprehensive than most stats packages for any language.

R – How to unload a package without restarting R

Try this (see ?detach for more details):

detach("package:vegan", unload=TRUE)

It is possible to have multiple versions of a package loaded at once (for example, if you have a development version and a stable version in different libraries). To guarantee that all copies are detached, use this function.

detach_package <- function(pkg, character.only = FALSE)
{
  if(!character.only)
  {
    pkg <- deparse(substitute(pkg))
  }
  search_item <- paste("package", pkg, sep = ":")
  while(search_item %in% search())
  {
    detach(search_item, unload = TRUE, character.only = TRUE)
  }
}

Usage is, for example

detach_package(vegan)

detach_package("vegan", TRUE)

Python: sort the list

>>> a = ['a','b','d','c']
>>> b = [1, 2, 4, 3]
>>> c = zip(a, b)
>>> c
[('a', 1), ('b', 2), ('d', 4), ('c', 3)]
>>> c.sort(key=lambda x: x[1])
>>> c
[('a', 1), ('b', 2), ('c', 3), ('d', 4)]
