There was a question in R forum very long time back.. on how to protect R Script files from inadvertent editing by users. There is a way to do this from within R, atleast in Windows XP I have tried this and it certainly works , The method is very different from the OS based folder protection route, however making available such a method in the open forum would only kill the very spirit of R.

Hi all, Does anyone have a comprehensive list of recursive-type objects in R? is.recursive defines them as by exclusion: "most types of objects are regarded as recursive, except for vector types, ?NULL? and symbols (as given by ?as.name?)." I think this that means recursive objects are: * lists * pairlists * calls * expressions Did I miss anything? Hadley -- Assistant

...ot;Curry" by using substitute et al. inside `foo`, - this would make it usable only within functions that one could be bothered to redefine this way - probably none.) Thanks in advance for any ideas and comments (including the ones saying that this is an awful idea) Best regards, Kenn Kenn Konstabel Department of Chronic Diseases National Institute for Health Development Hiiu 42 Tallinn, Estonia [[alternative HTML version deleted]]

Hallo! Is there a package in R that does Q-type factor analysis? I know how to do principal component analysis, but haven't found any application of Q-type factor analysis. Thx, Julia -- Psssst! Schon vom neuen GMX MultiMessenger geh?rt? Der kanns mit allen: http://www.gmx.net/de/go/multimessenger

Suppose X is a long vector of integers (typically about 30000 elements). Is there an efficient way to detect whether there are at least N consecutive zeros in X, and if yes, where does this occur? for example, suppose X is: 1 2 3 4 5 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3 4 2 0 1 2 0 0 0 2 2 2 2 2 ... and N is 10. I would like a foo(X, 10) to return something like c(6,19) (start and end positions in X

...element. So I'd suggest changig this too, replacing the lines like x$sec <- 0 by x$sex[] <- 0 (the second version would preserve the number of elements). (Changed version at the end). It doesn't seem like this change could possibly break any existing code.

...ot;) Packages should not make .C/.Call/.Fortran calls to base packages. They are not part of the API, for use only by R itself and subject to change without notice." I understand the reasons but what would be a good solution if I like the way it works now?

Dear R-users, Is there a way I can prevent global variables to be visible within my functions? Sebastien

Dear r-devel list members, On a couple of occasions I've encountered the issue illustrated by the following examples: --------- snip ----------- > mod.1 <- lm(Employed ~ GNP.deflator + GNP + Unemployed + + Armed.Forces + Population + Year, data=longley) > mod.2 <- update(mod.1, . ~ . - Year + Year) > all.equal(mod.1, mod.2) [1] TRUE > > f <-

Dear R, When I'm writing script I probably hit accidently some hot key and then the text in script is being overwritten by subsequent typing. Please what is the hot key or how can I disable it? -- View this message in context: http://r.789695.n4.nabble.com/random-typing-over-text-tp3470428p3470428.html Sent from the R help mailing list archive at Nabble.com.

Hello all I would like to ask your help use mapply. I have a function called findCell that takes two arguments(x,sr) where x is a vector of size two (e.g x<-c(2,3) and sr is a matrix. I would like to call many times the findCell function (thus I need mapply) for different x inputs but always for the same sr. as x is a vector of size two (two cells) I want to pass inside inside the following

Friends. I cannot simplify this much, and I think the loop is unavoidable. As a recovering C programmer I want to avoid loops and in cases like this I almost allways can by using an apply function. But I suspect in this case there is nothing I can do. It is a finance example where a price series is compared to a moving average. If the price goes above the average, plus a bit, buy the

Hi, I'm trying to execute the same R code on multiple data frames listed in a single directory. The code works fine if I use the code (below) for each file. However, I have several files and it becomes tedious to run each one, name it and then aggregate into a single dataframe. Name 0.0           1 21.15       2 2400.26   1 3222.14   2 name = read.table(file.choose(),header=F) #

Hi Is it possible to subset an n-dimensional array by a vector of n dimensions? E.g. assume I have > x <- array(1:24, dim=2:4) > x[1,1,2] [1] 7 > dims <- c(1,1,2) I would like a function that I can supply x and dims as parameters to, and have it return 7. Also, I would like to do something like: > x[1,1,] [1] 1 7 13 19 > dims2<- c(1,1,NA) And have a function of x and
