Greetings everyone, I have a problem which I believe is a collision between the --ignore-existing option and filter rules. It appears to me that regardless of argument order, when I specify the two on a command line, even if a non-existing directory appears in the filter list as a protect rule. But when I change protect rules to exclude rules, the excluded files/directories appear not to be

Hi, Im currently trying to debug a 'error in unprotect: stack imbalance' problem and I am curious about two basic questions on the use of PROTECT and UNPROTECT, which I could not figure out: - which objects have to be protected, namely, if the code is something like: SEXP fun, e; /* get the expression e ... */ fun = eval(e, R_GlobalEnv); /* or like this?: PROTECT(fun = eval(e,

I just got this error: > library(igraph) > comp <- decompose.graph(gr) Error: protect(): protection stack overflow Error: protect(): protection stack overflow > what can I do? the digraph is, indeed, large (300,000 vertexes), but there are very many very small components (which I would rather not discard). PS. the doc for decompose.graph does not say which mode is the default. --

Hi I'm trying to implement something similar to the following R snippet using C. I seem to have hit the wall on accessing class slots using C. library(fPortfolio) lppData <- 100 * LPP2005.RET[, 1:6] ewSpec <- portfolioSpec() nAssets <- ncol(lppData) setWeights(ewSpec) <- rep(1/nAssets, times = nAssets) ewPortfolio <- feasiblePortfolio( data = lppData, spec = ewSpec,

Hi, I have an SEXP obj in a C function called via .Call(). The obj is protected (in fact it is an argument to .Call and therefore automatically protected). If I set an attribute of obj does the attribute become protected too? Here is an example SEXP foo(SEXP obj) { SET_NAMES(obj, NEW_CHARACTER(3)); /* are names protected or not? */ ... } Thanks, Vadim [[alternative HTML version

Apologies first, because I need to ramp up on Ruby and coding Ruby in Rails, however it''s my 3rd day with this beast :) so I''m asking : When I added protected methods to the model before it was like: protected method.................... end Would this be a valid way to write a protected method as well ?: attr_protected :column1, :column2 Perhaps this particular call

I received the following note this AM. The problem is, I'm not quite sure how to fix it. Can one use PROTECT(coxlist(eval(PROTECT.... , do I create an intermediate variable, or otherwise? I'm willing to update the code if someone will give me a pointer to the right documentation. This particular chunk was written when there was a lot of change going on in the callback mechanism and

I want to write an R function using R's C interface that takes a 2-column matrix of increasing, non-overlapping integer intervals and returns a list with those intervals plus some added intervals, such that there are no gaps. For example, it should take the matrix rbind(c(5L, 6L), c(7L, 10L), c(20L, 30L)) and return list(c(5L, 6L), c(7L, 10L), c(11L, 19L), c(20L, 30L)). Because the output is

I'm trying to get a reference to this object in C SWX.RET[1:6,c("SBI,"SPI","SII")] While i am able to access and use a plain SWX.RET object, I'm getting confused on how to create an object with the array subscripts like above. Here is what I tried to do. It doesn't work because "[" is obviously not an operation or function on SWX.RET. So how do I

I have a few simple questions about the usage of PROTECT, more specifically how careful one needs to be. Simple yes/no answers are fine. Most of the uses I have seen do protection when memory is allocated. But what if one just want to assign a value of another function to a variable. Say eg. that foo is a function that returns a SEXP. Would the following code be fine? SEXP bar;

I'm following the instructions on this URL http://wiki.centos.org/HowTos/RT_3.4.x_On_CentOS_4.x and came across the part that said "WARNING: RT overwrites some packages from the base distribution, especially mod_perl" How exactly do I "protect" the RT repository? It links to the "ProtectBase" program http://wiki.centos.org/PackageManagement/Yum/ProtectBase

In SmallVector.h: class SmallVectorBase { *protected:* void *BeginX, *EndX, *CapacityX; *protected:* SmallVectorBase(void *FirstEl, size_t Size) : BeginX(FirstEl), EndX(FirstEl), CapacityX((char*)FirstEl+Size) {} In StringMap.h: class StringMapImpl { *protected:* // Array of NumBuckets pointers to entries, null pointers are holes. // TheTable[NumBuckets] contains a sentinel value

First, thanks to those of you who responded to my previous post about my code that was taking longer and longer to process. After following your suggestions, and I now thinking that the problem was some calls to Rf_duplicate in my C code. So I'm hoping I could get some clarification on what Rf_duplicate actually does. What is the real difference between PROTECT(y=x); and PROTECT (y =

Hello, I have created a vector with 2 elements(see code below) I am calling this function many thousands of times (hundreds of thousands) after some time i get *** caught segfault *** address 0x5, cause 'memory not mapped' However, if i dont set the R_NamesSymbol, I do not get any such error. Am I doing this correctly? Thank you Saptarshi ==CODE=== // kxp and usar are two SEXP's

I've been attempting to perform some analysis on a model that was interfaced with R (R calls a library that takes SEXPs and converts the data frames into the internal structures of data), and I notice that for small data.frames the vectors don't get corrupt (n<200-ish). When I pass in larger data.frames, the vectors will become corrupt. I've been PROTECTING the heck out of

Hi, Is it not ok to use both plugins at the same time? I have read from the wiki page of centos that you must use only either protect base or priorities plugin. I have been using the the config file below for months and did not encounter any problems. I used priority=1 and protect=1 on base and updates (addons,extras protect=1 ; set no priorities) for the CentOS-Base repo and on the rpmforge

Dear List, I stepped into a strange effect which I can't explain to myself (probably due to lack of knowledge on R internals). I have four vectors a,b,c and z of size 10000 each. With these vectors I call .Call("hyp2f1forrey", a, b, b, z, PACKAGE = "hyp2f1") to access SEXP hyp2f1forrey(SEXP a, SEXP b, SEXP c, SEXP x) { int i,n; double *xa, *xb, *xc, *xx,

Hi list, I have a bunch of .csv files that are password-protected. I wonder if there is a way to read them in in R without manually removing the password protection for each file? Thank you very much! ...Tao [[alternative HTML version deleted]]
