Hello, I have a question about addTaskCallback It is said that the argument visible allows to know wether the result of the top-level evaluation was printed or not. Nevertheless, in the following example, I encountered a problem, as it seems not all printed objects are visible... Could someone tell me where is the tip? TIA

Hello, Rather new to RoR, so I''m not sure about the terminology and such :-/ . My question is: how could I know the model which is associated to a controller? For example: - controller class is TestController, which is a subclass of ApplicationController - associated model class is Test How could I write some code in a method of ApplicationController to dermine the current

Hi Alejo, According to my knowledge the two plots are different because in the first one a point belongs to a group depending on its group in the data whereas in the second plot a point belongs to the group predicted by the linear discriminant analysis. I hope somebody will correct me if I am wrong. Alain Alejo C.S. wrote: > Hi Alain, this is the code: > > > library(MASS) >

Hello, How can I pass a hash as parameter from a template with url_for? e.g. : if I have test = { :a => "a", :b => "b" } How can I pass that with my request? Is it possible to pass nested hash''es to? Right now, url_for :action => :test, test doesn''t seem to work. Thank you, --

Dear R user I have 2 problems with lmer. The statistical consultance service of my university has recomended to me to expose those problems here. Sorry for this quite long message.

Hello, It seems I need to restart webrick everytime I modify a module in order for my modifications to be taken into account. Is this normal and is there a workaround?

Hello, I have a People table and a Addresses table. A person can have one or more addresses, but should at least have one, so there is a address_id field in People. Now, I would like to have a form to fill the name of a new person and its address from the same place. I could use person.address.country, for example (it works), but I would like to simply use person.country for some reasons

Hello, I am actually developping a libary under S+/NT in which I do modify the .Program. Is there any equivalent in R? (the .Program is the command line parser, ie the function which is called when you press enter and pass the commmand line to the internal program) TIA Eric ?-----------------------?--------------------------------------------------? | Eric Lecoutre | DEA de

Hello, I always have the same kind of design problem, which I am not sure how to solve correctly: - say I have a variable, "status", which I want to calculate once in my controller, and access a couple of times in my view - "status" variable initialization could happen in a subclass, overriding the regular method for that What I do now is using an instance variable

I'm trying to assign NAs to values that satisfy certain conditions (more complex than shown below) and it gives the right result, but breaks the loop having done the first one viz: new<-c(rep(5,4),6) for (i in 1:6) {new[new[i]>5.5][i]<-NA} gives the correct result, though an error message appears which causes a break if it's in a loop. If I can get rid of the error message and

Hi to all R/S gurus, I am developping a library to export R/S objects to HTML (there was developments of this library past year, by myself and Mathieu Ros, but we never finished it). For that, I wrote HTML.* functions handled by the generic method HTML. At this step, allmost all objects exportations are possible: matrix, atomic, data.frame, functions and even plots... but I still don't

Hello, I am using the recode() function in Rcmdr and the result is not what I expect so I am almost sure I did something wrong but what... > test <- data.frame(x=1:10) > library(car) > recode(test$x,'1:5=0 ; else=1', as.factor.result=TRUE) [1] 0 0 0 0 0 1 1 1 1 1 Levels: 0 1 BUT > library(Rcmdr) # recode from the car package is now masked Now I recode test$x

Hi all, Is it possible to add a permil (or per mille) symbol to an R plot (I couldn't find this symbol under demo(Hershey) or the plotmath information). In some ascii tables it is symbol no. 137. cheers, Matt. [[alternative HTML version deleted]]

Hi R-listers, I am trying to better undertand what we would call "functional paradigm" use of S/R to better map my programming activities in other languages. This little function is aimed to create an object (at the end end, it would have it's own class): -- myObject =function(){ list( a=1, foo=function(b) { cat("b:",b)

One more question: Is there some way to set the human_name of a column? e.g.: human_name for column address1 shouldn''t be Address1 but "Address, line 1". If not, should I make a hash with my custom names?

There is a little problem in handling logicals in RMySQL: # here is the MySQL connection > con <MySQLConnection:(1816,0)> # here is the data frame > print(a<-data.frame(x=c(TRUE,FALSE),y=c(FALSE,TRUE))) x y 1 TRUE FALSE 2 FALSE TRUE # as promised, the two data frame columns are identified as logicals and # the field types are set to tinyint > field.types <-

Dear useRs, I have written a very simple function to compute some probabilities on words (function is below). The function includes a which() statement applied to a vector of characters (word.split): sapply (word.split, function(x) which(letters==x)). This statement worked as expected when used outside the global function : > word <- "hello" > (word.split <-

Hello, I would find it very usefull to have the ability to load packages with options. Consider for example the SciViews package Philippe and me are working on. When loading on Windows, it automatically loads the associated GUI executable. It should be convenient to have an option not to load the exe but still have an access to the R functions of the package. For that, I think a simple change

I was wondering whether somebody has developed a set of Textpad macro that work with R the same way as WinEdt does. I use Textpad for almost everything (programming, creating LaTex docs, etc.), it will be nice if I can use it as my R program editor. Or maybe someone can tell me how that kind of macro works so that I can develop my own macros. Thank you! Best, Shige Song Department of Sociology,
