Good article on matching methods

Very good article indeed. The authors have made quite a few number of excellent points.

SciViews key binding

• Shift-F1 for contextual help on the word under the cursor in the editor
• Alt-Shift-F1 for help search selected word (make sure to look at the Web menu too)
• Ctrl-T to expand abbreviation (try typing func, then hit Ctrl-T in a file previously saved with a .R extension; a tooltip also appears when the sequence you type corresponds to a recognize abbreviation... and there are dozens of them already defined!)
• Ctrl-Return is the same as Return but also run the line of code in R
• Ctrl-Shift-R to run selection and/or code line by line
• Ctrl-Shift-A to run all code in the current document in R
• Ctrl-Shift-H to run a paragraph (consecutive lines of R code)
• Ctrl-Shift-M to run code between two bookmarks (define bookmarks first!)
• Ctrl-Shift-S to summarize the object whose name is under the cursor
• Ctrl-Shift-L to plot the object whose name is under the cursor
• F3 to search next occurence of the word under the cursor
• F4 to list R objects in memory (in .GlobalEnv)
• F7 to set the R working directory to the dir of the current edited file in Komodo

Semi-automatic table making

Both Stata and R have nice table making facilities, but aML is still lacking this. Here is how I convert aML outputs into Word tables.

1. Estimate aML models;
2. Use "maktab" facilities to put different models into one output;
3. Copy and paste the results into a text file;
4. Use Excel to read in the file;
5. Copy and paste the Excel worksheet into Word;
6. Edit the Word manually from there.

When I have time, I may write a python script to automate this process; but for now, this seems to work reasonably well.

Camifox

Firefox is my browser of choice, and camifox is my favorite firefox theme: http://www.altmusictv.com/camifox/

Idiot-proof vs. idiot

I like this sentence: "Programming today is a race between software engineers striving to build bigger and better idiot- proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning."

Komodo Edit is a real deal

Komodo Edit is a free open-source and cross-platform editor geared toward programmers. So far, it is the closest thing to the Windows-only UltraEdit or Vedit in the free Linux world. It is very configurable, and unlike Emacs, it does not require one to know Lisp.

I have been using it for several days, and just found myself doing all my texting editing, R, Stata, aML, Python, in it. Wow...
