Hi I'm trying to develop some C code to find the fixpoint of a contraction mapping, the code compiles and gives the right results when executed in R. However R-gui session is frequently terminated. I'm suspecting some access violation error due to the exception code 0xc0000005 In the error report windows 10 gives me. It is the first time I'm writing any C-code so I'm guessing I

Is there a missing value constant defined for R_xlen_t, cf. NA_INTEGER (== R_NaInt == INT_MIN) for int(eger)? If not, is it correct to assume that missing values should be taken care/tested for before coercing from int or double? Thank you, Henrik

Are the problems with yum in the Centos 4.3->>4.4 upgrade process due to a forked or obsolete version of yum? I briefly scanned <https://lists.dulug.duke.edu> and didn't see any problems, but did see some incidents regarding yum hangs reported about a year ago. regarding the current upgrade, Seth Vidal in

Dear list, I am a little puzzled by computing time in connection with calling C functions. With the function mysolve1 given below I solve Ax=B, where the actual matrix operation takes place in mysolve2. Doing this 5000 times takes 3.51 secs. However, if I move the actual matrix inversion part into mysolve1 (by uncommenting the two commented lines and skip the call to mysolve2) then the

Hi, I am writing an R package with two functions in C++. So far everything works. Now, i would like to write a third function which would use a pointer (it is a pointer to a class object) created by first function. I tried placing this pointer outside of the function definitions (i.e to make it global) but when called in the 3rd function i get > *** caught bus error *** address 0x0,

Dear all, I am sending a patch for extending pdf device to embed popup text and web links. I implemented this feature by using annotation object, a interactive feature of pdf. You can see a sample code for using this feature in the following, and sample pdf is in

Dear all, [system and version information below] I am trying to modify a C function for finding the root of an expression. The function is to be called from R as .Call with input parameters: f: expression for which we will find the root guesses: interval for the solution stol: tolerance rho: environment The original functions I use are: SEXP mkans(double x) { SEXP ans; PROTECT(ans =

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

Hello, The current xfig device lacks the functionality to set the textspecial flag and use the defaultfont in xfig. This is necessary when you want to export to xfig and use interpreted text (e.g., $ \frac{1}{e}$ gets interpreted by latex). The attached patch adds this functionality. Why would you like to do this? - Use math in labels (e.g., name your variables $r_{xy}$, do a

I am grateful for the advice of Douglas Bates on my earlier problem in making R-0.62.1, but I'm afraid I'm still having problems.... I have been installing the various updates to R for quite some time on my alpha, and it is only now that I have been having really severe problems. The three or 4 versions before 0.61.1 installed without error. For 0.61.1 I needed to install GNU make. For

Hi, Whenever I have a MySQL query that returns a Decimal result to R I get the following warning in R: Warning message: RS-DBI driver warning: (unrecognized MySQL field type 246 in column 1) I get this for a simple query like "SELECT 2, 2.5" !! I am using: R ver 2.1.1 RMySQL ver. 0.5-7 DBI ver. 0.1-10 MySQL Ver 14.12 Distrib 5.0.18. Please Help! Jason

This is a message for someone familiar with the implementation. Superficially the R code for seq.default and the C code for seq.int appear to be semantically very similar. My question is whether, in fact, it is intended that behave identically for all inputs. I have found two cases so far where they differ, first that seq.int will coerce a character string to a real (via Rf_asReal) whereas

Hi all, Could anyone point me to one or more examples in the R sources of a C function that is called without knowing in advance what will be the length (say) of the output vector? To make myself clearer, we have a C function that computes probabilities until their sum gets "close enough" to 1. Hence, the number of probabilities is not known in advance. I would like to have an
