Dead Gateway Detection
Hi, I have a linux box loaded with RH7.1, 3 ethernet with load balance on 2 ISP. In theory, if one router stop to work (I have turn off for this try), the Dead Gateway Detection, would re-instradate alla traffic on other link. This not work...someone have more experience on this? Giorgio Biondi

Porting let* from Common LISP to R
In porting some Common LISP code to R, I am trying to found out whether special care must be taken for the let* function. In Common LISP, "the let* block is like let except it is guaranteed to evaluate the initialization of its local variables in sequentially nested scopes, i.e. it provides an order to the binding and visibility of preceding variables.". I have included the recursive

tkcanvas/bitmap for Turtle World
To represent a turtle inside a canvas (tcltk package), I have a serie of bitmaps representing the turtle heading in different directions and I would like to display the one that corresponds to the current direction of the turtle (function below). I have created with Paint a bitmap representing the turtle in BMP format and succeeded displaying it on canvas after converting it into XBM format

"Turtle world" graphics in R
I would greatly appreciate some idea about the best approach to make a graphical interface of for a turtle world in R. In the turtle environment, the user controls movements of a turtle through the command line (e.g. forward(10), turn(5), etc.). The turtle should be displayed in the new position and heading after each command. Also, the turtle's path and, possibly, objects (squares,

Implementing streams in R
Thanks to Prof Brian Ripley, Duncan Murdoch and Luke Tierney for your replies. In particular, I found Luke Tierney's info very useful. I just would like to answer Duncan Murdoch's question (what is a stream [Lazy list in Luke's implementation] in plain english?) in case it interests somebody else. In fact, I will quote from "Structure and Interpretation of Computer

Difficulties with R.oo (static fields, etc.)
I would like to use R.oo and tcltk to implement a Turtle World. I have encountered many problems because: 1) I am not sure how to implement static fields with R.oo 2) I am not sure how to implement a constructor that would call a function only for the first instance of a class (i.e., to initialize value of static fields only once) 3) I am not sure how to remove/delete cleanly existing

Implementating streams in R
Dear all, I have an implementation of streams in R. The current implementation of delay() and force() is inspired from the LISP implementation found in Part VI "Languages for AI problem solving" of "Artificial Intelligence" by G. Luger. I have tested it with the Fibonacci example in the same book (see examples below). It works but I do run into a problem when I try to

Implementation of the names attribute of attribute lists
Dear all, Internally, the attribute list appears to be implemented as an generic list vector with a names attributes (i.e., the attribute slot in the object's SEXPREC structure would point toward a VECTOR_SEXPREC representing a generic vector). > attributes(c(a=1)) $names [1] "a" > typeof(attributes(c(a=1))) [1] "list" From R, it appears as if the named list had

how to adjust link function in logistic regression to predict the proportion of correct responses in 2AFC task?
I have would like to use logistic regression to analyze the percentage of correct responses in a 2 alternative forced choice task. The question is whether one needs to take into account the fact expected probabilities for the percentage of correct responses ranges between 0.5 and 1 in this case and how to adjust the link function accordingly in R (see details below).

backward stepwise model selection
Hi All, I know in R there is function named 'step', which does the stepwise regression and choose the model by AIC. However, if I want to choose a model per this logic: 1. Run a full model (linear regression, f = lm(y ~., data = ZZZ), for example) 2. Pick up the variable with biggest p value, delete it from the module and get a new regression model. 3. Repeat step 2

Applying variable labels across a data frame
Hi All, I'm working on a class example that demonstrates one way to deal with factors and their labels. I create a function called myLabeler and apply it with lapply. It works on the whole data frame when I subscript it as in lapply( myQFvars[ ,myQFnames ], myLabeler ) but does not work if I leave the [] subscripts off. I would appreciate it if anyone could tell me why. The program below
