Interpreting as.factor
When I run a linear regression and include a variable in the
regression with as.factor i.e.
lm(y ~x +as.factor(x1)
and i read the output as
as.factor(x1)1....
as.factor(x1)2...
etc.
how do i interpret the estimate for each level? Is this simply to be
regarded as a shift in the equation predicted by the intercept and
independent variable x?

As.Factor with Logistic Regression
I am modeling the probability of player succeeding in the NFL with a
binomial logistic regression with 1 signifying success and 0
signifying no success. I performed the regression of the binomial
variable against overall draft position using the college conference
for which each player played as a factor using the
as.factor(Conference) command.
My question is:
How do I plot specific factors

Testing for Significance Between Logistic Regressions
This is more of a statistics question with implementation implications.
I have used R to calculate logistic regressions for various
characterstics. I would now like to verify that the difference
between a particular subset is significantly different from the
logistic regression of the entire set.
Example.
I have a logistic regression containing every running back drafted
between 1980-2000. I

Fw: Re: Creating users via Perl Net::LDAP
Thanks for the input Mike,
I set the attributes, as best I could, to mirror those of another account created using the samba-tool per the howto. Reviewing the attributes of both accounts, I see nothing about them being "enabled" or "disabled."
For the password I used "userPassword," specifically with a utf8 encoding, per a previous message:

tkbutton command - how to know which button was clicked?
In the below code fragment, print(arg) always prints the
last element of rekeningen$rekening.
Is this because of lazy evaluation? I.e. arg is evaluated at
the time the button is pressed?
And, if so, how can I avoid this?
I tried function() {force(arg); print(arg)} but that didn't work either.
Thanks,
Jeebee.

Installation on Mac OS X 10.3.2 with Fink readline and headers
Hello!
I'd like to install R on my machine in order to work with Joe Conway's
pl/R in PostgreSQL. I'm running Mac OS X 10.3.2 with readline installed
via Fink. I downloaded the Rdevel.dmg, and installed first
Rframework.pkg and then Rapp.pkg. (I did not install the
J_libreadline.pkg, J_libxml2.pkg, or J_tcltk.pkg also included on the
disk image.) Both Rframework and Rapp

Creating users via Perl Net::LDAP
Hey there folks,
I put together a little Perl script that makes an LDAP connection to a Samba4 server and creates the cn=username,cn=users,... part of a user account.
It appears that this is not sufficient to get a fully functioning Active Directory type log-in; from the howto I can deduce that my effort is missing a sidMap, and there might be a good deal more to creating full AD users and

Point'n Print setup on Samba4 failing to install drivers
Premise / status: I've set up Samba 4 as an AD controller, and, according to the instructions on the [howto](https://wiki.samba.org/index.php/Samba_as_a_print_server), have established a [print$] share that should allow me to "upload printer drivers for Point'n'Print driver installation." The printers are visible from the Windows client, but the server does not have Windows

Roaming profiles won't roam via how-to

I've been testing Samba 4 with some Windows 7 virtual machines and the Active Directory how-to instructions here: http://wiki.samba.org/index.php/Samba_AD_DC_HOWTO.
As far as I can tell, the instructions work exactly as described, except when it comes to roaming profiles. When I attempt to use those, the user can log in but gets a message warning that Windows could not load their

several plots in one
Can anyone tell me how I can supply more than one graph to plotCI
(gplots) at once?
Below is what I tried, also with rbind instead of cbind.
What is the way to do this (in general, I think)?
Problem is that lines of 1-st and 2-nd series are mixed, while they have
nothing to do with each other.
I also tried calling plotCI with argument add=TRUE, which didn't seem to
work (that is actually

The IWigdets::combobox has an option "selectioncommand" to specify a procedure

Does ComboBox from Bwidgets have an equal option or is there a simple method to

Truncating leading zeros in strings
I am new to R. I thing this will be simple, but I don't yet know my way
around.
I am generating character strings from the system clock that represent
integers, and I want to convert them to integer values. Strtoi works
well, except when there are leading zeros on the string. Could anyone
suggest a way to remove those leading zeros?
Thanks
