Passing the parameter (file name) to png()
I am fitting 3 parameter model to my response matrix and want to generate
item characterstic curve.
I want to specify file name to save item characterstic curve by passing it
as external parameter to the R batch script. The following is the code I

*R Script:*
library(ltm)
cmd_args = commandArgs();
for (arg in cmd_args) cat(" ", arg, "\n",

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 have created an object, logistic.glm. I also

Dissimilarity Analysis
Hello you all!
I am a completely new user of R and I have a problem to solve.
I am using Mac OS X on a PowerBook.
I have a table that looks like this:
species X1 X2 X3 X4 X5 X6 X7 X8 X9 X10 X11 X12 X13 X14
X15 X16 X17 X18 X19 X20 X21
