For those of you who haven't used R before, I uploaded a brief
introduction to R which is written by Dan Ho for another class. It's under
``Handout'' on the course website.
A reminder that today I will hold an extra office hour right after the
lecture in my office at CBRSS. Tomorrow, I will have a regular office hour
from 4 to 6pm.

i get the following error message when i run logit regression in R. any idea
what is wrong?
> model <- glm
(P98transition~ioscore+dioscore+pcGDP+dpcGDP+contagP98+pastdemP98+regionalmids+
domviolence+milreg+indep, family=binomial(logit))
Error in gamma(N + 1) : Object "logit" not found
everything is in one line. so the problem is not the line break.

Each of you, and NOT each group, should bring the following:
(a) a floppy disk containing the data, the program, and the description of
your replication procedure and results.
(b) two hard copies of the description of your replication procedure and
results.
(c) a hard copy of the replication article.
We will assign another student to replicate your results. This assignment
will be done by each student rather than by each group.

how do you obtain probit coeffcients in spss, specifically spss asks for response freq, total observed and factor, are these analogous to dep. var and indep. var? thanks....
Burning the data on the CD is nicer for the student who is going to
replicate your results, but if you can't, sure just e-mail them.
It would also be a good idea to include your e-mail address in your
writeup.

Dear Kosuke,
Our datafile is alas huge, and won't fit on a disk. Would it be OK to add a
note saying that we will email it to whomever is assigned to replicate our
work?
Many thanks!
Best,
Dan and Colin

Each "person" not each group should turn in the assignment.

The replication assignment is due tomorrow in class. Here is the reminder
about what you need to turn in.

Subject: [gov2001-l] IMPORTANT: replication assignment
Hi everyone,
A few things about the replication assignment:
1. First and most important, please turn in your assignment on time. Since
the next assignment is going to be the replication of someone else's
replication results, your late homework would cause a trouble for another
student in the class.
2. You can use any statistical package you want. If it's easier, you can
use SPSS, STATA, or whatever. The only reason we recommend that you use R
is that it's a nice software that allows you to do more than SPSS or
STATA. But, this assignment as well as all the other assignments will be
evaluated solely based on its quality not on what program you used.
3. In your Hw#5, indicate the title of your replication article and your
coauthor.
4. On March 31, "each" of you should turn in the following:
(a) a floppy disk containing the data, the program, and the description of
your replication procedure and results.
(b) two hard copies of the description of your replication procedure and
results.
(c) a hard copy of the replication article.
Good luck!
Kosuke

Discard the previous message. Here is a better way...
1. In your home directory,
mkdir .R
to create a directory for R
2. Create .Renviron file in your home directory, and
add the following line at the top of the file.
R_LIBS=~/.R/library
You can also define other things such as
R_NSIZE=5000k
3. Restart R
4. Type
options(CRAN ="http://cran.us.r-project.org/")
install.packages("car")
library("car")
