R, Delphi, C: Programming Tips and Downloads

Libraries for Delphi and C

Delphi components to generate files for Statistica by Statsoft, and speak Statistica-VBA from Delphi. Free with sources.
RDelphi demonstrates how to use the R from Delphi. Revised June 2004, can handle strings now. Uses Thomas Baier's RDCOM.
DLL version of Jake Janovetz' FIR design program, with sources.
Argonne lab LMDIF, solves or minimizes the sum of squares of m nonlinear functions of n variables. This is the C translation by Steve Moshier, ANSI-ized and with dynamic memory by Dieter Menne. Source only.
We used Texas Instruments TMS320C3x/4x Code Composer to develop DSP programs for biomedical sound processing. Both are great tools, but Code Composer 3.0x has some annoying undocumented quirks. See Code Composer tricks and workarounds to avoid re-discovering the broken spoke.
When developing AlphaTrigger for EEG-triggering, we noticed a strange effect with large FIR-filters computed with the standard Remez algorithm.

Free Programs

WoIstWer: Who-Is-Where in the hospital or in the office? A free program to manage examination room occupation.
RanBlock is a no-frills free program to generate tables for a randomized block design.
Weimin Liu has written a Windows interface for Ken Steiglitz' constrained FIR design program. Since the original link to site seems to be dead, you can download it from us.

A Joomla 1.5 module that reads in CSV telephone directory, stores the data in Contacts and displays an AJAX-enabled no-click-required search can be downloaded here. The search is fairly generic and should work with all contact data, but the csv-import must be changed to adapt to your needs.

With phpSerialize, available from the CRAN repository, you can use the power of the statistical programming language R in your web application.
toggleDoc is a Perl script to convert R-documentation index files into a format were redundant information can be hidden from display (Readme, example).
Dmisc: A collection of tools to produce LaTeX tables for linear models (lme and lm) can be downloaded from here. The package passes CRAN tests with warnings, but I do not plan to upload it to the general repository because it is a bit to much personalized. The feature I like most is a row-wise dynamic rounding scheme in LaTeX tables with the number of significant digits determined by the standard error of the estimate. I implemented this after hours of discussions with medical researchers who love to give 8 significant digits ("but this is from Excel") for estimates with standard errors of 20%. This package uses Frank Harrell's Hmisc library.

How to draw CONSORT-Diagrams for medical publications with LaTeX and PSTricks. This is the sample CONSORT diagram from August 2005, the LaTeX script, and the pdf-output produced by the script.
Another way to draw a CONSORT diagram from database information. It uses Tikz which can be used easier with PdfLateX. You should know Sweave to use it. Here is the zip-file.

A filter to crop black and white image borders on scanned photographs for JAlbum and ImageMagick. Here is the Javadoc documentation of CropBordersFilter, see also the JAlbum filter documentation for instruction how to use it. Download current version 0.81 here.
