Notes on R statistics and programming language

Test.
Finally got X-windows to work reliably. Had to use xf86config (dpkg-reconfigure xserver-xfree86 did not put enough options into the XF86config-4 file, that is, the file that X actually uses.) By trial and error I commented out "Option no_accel" and that seems to work. I have also saved the config file as XF86config-4.finallyworking. Very frustrating problem, of course, because it was sporadic. Also, am worried that it went from working to non-working. Does something re-write XF86config-4?

Major debian headaches. Turned off the computer tried to switch the disk drive for the cd-rom. Reboot failed. X-windows starts and then freezes up. Have tried lots of variants but to no avail. Can start out of X-windows but can't make X-windows work reliably.
Currently using dell101 keyboard specification. Problem? Maybe will try pc101 instead.
Very frustrating after great first week with Debian.

Will use this blog as my general computing notebook.
Installed debian on the old laptop. Base install was pretty easy. Misallocated space a bit; /tmp is probably too small because mozilla tries to save files there. Use wget instead.
Had some trouble with the X-windows install; couldn't identify the graphics driver in the Dell Inspiron 3200 (tried ATI Rage Pro which is used in my 4100) Eventually found NeoMagic listed on the web. All around good web site. Touchpad mouse is /dev/psaux, Keyboard is Dell 101 key. Horizontal sync rate is option 6 or 7. Need to adjust the screen with Ctrl-Alt-- after bootup.
Have installed fvwm2 and made some buttons.
Installed jpilot and the pilot-link suite. Must export PILOTPORT=/dev/... before sync-ing with jpilot. (I think it's ttyUSB1 (not ttyUSB0).
Also installed the verizon connection using the pppoe application. Launch with pon, close with poff.
The laptop seems a bit slow. Model is 266 MHz I think. RAM shortage? 64MB.

Installed R on the debian box at home.
Useful functions and packages:
in the nlme package, gls will estimate models with ARMA(p,q) and AR(1) residuals
in the car package, linear.hypothesis will test linear hypotheses after estimation.
Looking for delta method for nonlinear hypotheses.

Will also include notes on SQL efforts here.
Have installed mysql and postgresql on the Linux box. The client for postgresql is psql.
I have installed a dbf to mysql converter. It is dbf2mysql and it is installed in ~mash/mysql-downloads/dbf2mysql-1.14/
To convert COSTAT01.DBF to sql, for example, use
./mysql-downloads/dbf2mysql-1.14/dbf2mysql -h localhost. -d mash -t test
-c -P password -U mash /mnt/cdrom/data/COSTAT01.DBF
The R-to-SQL package works:
library(RMySQL)
Then see R-packages/tips.txt for how to establish the connection.
SQL clients seem pretty picky about how the hostname, user, and password are entered. Unhappy about plain text passwords.

TCL per advice on

Installed ActiveTCL to the laptop to try out the tcltk package. Added environmental variable TCL_LIBRARY and changed PATH. Had to copy tcl84.dll and tk84.dll to tcl83.dll and tcl83.dll (note name change) in the R binary directory to make tcltk work (complained couldn't find the ...83 files).
