...docs for segmented I can access all of the slope parameters via a named vector of the coefficients. How can I access the slope segments or locations? I have never tried to annotate an R plot before, so I don't even know how to 'pin' a bit of text to an x,y location on a plot. > dput(bullard) structure(list(Rt = c(14.4477, 23.6752, 26.723, 33.8508, 37.9628, 47.0804, 49.7232, 54.6395, 59.9251, 64.7518, 81.1629, 85.7209, 88.0334, 98.366, 102.6563, 105.6953, 134.8691, 137.3795, 155.0056, 158.6707, 162.0671, 206.7413, 248.701, 255.9407, 265.5201, 283.1462, 288.8939, 299.8356, 311.0788, 323...

I think that this is an easy one... I have a matrix where each row is an (x,y,z) triplet. Given a potential (xnew,ynew,znew) triplet I want to know if the matrix already contains a row with the new values (the space already has that point). I can do it using a for loop, but I would like to know if there is anyway in which I can do it without the for loop. I do it now like this (this

...understood the documentation this seemed like the correct usage. It seems like I could really just do the following: return NEW_LIST(0); but I thought I'd better ask first. Thanks in advance, I hope I did not miss something in the documentation which describes this. Thanks, jim -- James Bullard bullard@berkeley.edu 760.267.0986

This might fall under the purview of bundles, but I could not find any example bundles which demonstrated what I am after. I would like to construct two packages (A, B) which utilize a number of common C functions. The most straightforward way to do this is just copy the relevant .c and .h files from one src directory to the next, but this is tedious especially in the face of multiple

I'm using external pointers and seemingly leaking memory. My determination of a memory leak is that the R process continually creeps up in memory as seen by top while the usage as reported by gc() stays flat. I have isolated the C code: void h5R_allocate_finalizer(SEXP eptr) { Rprintf("Calling the finalizer\n"); void* vector = R_ExternalPtrAddr(eptr); free(vector);

Hello, this is probably something silly which I am doing, but I cannot understand why this allocation is not happening. Here is a my C code which tries to allocate a list of size 333559, and then a matrix of size 8*333559 I thought I might be running into memory problems, but R is not even using that much (I start R with more memory and it stays constant) Also, I start R as I normally do and I

Hello all, thanks for all the help on the other issues. This one should be relatively straightforward. I have a vector of integers which I allocate to be the maximal size possible (meaning I'll never see more than cel.GetNumOutliers, but most likely I'll see less) therefore, I want to resize the vector, one solution would be to allocate a new vector then to copy into the new vector. That

Hi All, I am interfacing to some C libraries (hdf5) and I have methods defined for '[', these methods do hyperslab selection, however, currently I am limiting slab selection to contiguous blocks, i.e., things defined like: i:(i+k). I don't do any contiguity checking at this point, I just grab the max and min of the range and them potentially do an in-memory subselection which is what

Hello all, I am writing an R interface to some C++ files which make use of std::wstring classes for internationalization. Previously (when I wanted to make R strings from C++ std::strings), I would do something like this to construct a string in R from the results of the parse. SET_VECTOR_ELT(vals, i++, mkString(header.GetHeader().c_str())); However, now the call header.GetHeader().c_str()

Hi, I recently ran into this problem. I couldn't find any mention of it in the setClass documentation. setClass("Foo", representation(file = "character")) setMethod("initialize", "Foo", function(.Object, file) { print(file) }) setClass("Bar", contains = "Foo") And the error: Error in print(file) : argument "file" is

Hi All, I am confused about the following code. I thought that the problem stemmed from lazy evaluation and the fact that 'i' is never evaluated within the first lapply. However, I am then confused as to why it gets bound to the final element of the lapply. The environments of the returned functions are indeed different in both cases and each environment has a local binding for

I'm trying to do the following: > setClass("MyNode", representation(parent = "MyNode")) [1] "MyNode" Warning message: undefined slot classes in definition of "MyNode": parent(class "MyNode") I scanned the docs, but found nothing. The representation function has no problem, it's the setClass function which gives the warning. What

Currently in R, constructing a string containing values of variables is done using 'paste' and can be an error-prone and traumatic experience. For example, when constructing a db query we have to write, paste("SELECT " value " FROM table where date ='",cdate,"'") we are getting null result from it, because without (forgotten...)

...I tend to like to build/install things locally so that aspects of the system I am working on don't cause problems later when attempting to install elsewhere. To this end, I build and install the hdf5 libraries w/out incident: tar xzf hdf5-1.8.4.tar.bz2 cd hdf5-1.8.4 ./configure --prefix=/home/jbullard/scratch/hdf5_install make && make install Now, I make a shared object using the following (I am compiling hdf5.c directly in src of the hdf5 package): gcc -I/home/jbullard/projects/me/R-builder/lib64/R/include -I/home/jbullard/scratch/hdf5_install/include -I/usr/local/include -fpic -g -O2...

Apologies if I am not understanding something about how things are being handled when using S4 methods, but I have been unable to find an answer to my problem for some time now. Briefly, I am associating the generic '[' with a class which I wrote (here: myExample). The underlying back-end allows me to read contiguous slabs, e.g., 1:10, but not c(1, 10). I want to shield the user from this

Hello, first off, thanks for all of the previous help; hopefully someone will have some insight on this question. I am attempting to track down a segmentation fault which occurs only after a detach(2) is called in the code (I have replaced the detach(2) with detach(package:DSA) and that fails as well (furthermore, I have removed the detach calls and it does not segfault)). It has proved
