similar to: CHAR(STRING_ELT( - OK but CHAR(asChar(STRING_ELT( - not, why?

Hi, I have a package where I do things like this a lot: if(strncmp(CHAR(asChar(Scategory)), "chance", 6) == 0) category = h_category_chance; else if(strncmp(CHAR(asChar(Scategory)), "utility", 7) == 0) category = h_category_utility; else if(strncmp(CHAR(asChar(Scategory)), "decision", 8) == 0) category = h_category_decision; else

Hey all, new R user and first timer here. I've been using getGraphicsEvent() on an X11-Xlib device in a kind of interactive loop, and would like to be able to stop it from printing newlines in the console when I don't actually want to print a prompt. Even an empty "" value still causes a newline right now. To not break any code that depends on this behavior, I figured getting

Hi there, I'm very new on R and I hope someone can help me to solve the problem in using the ifelse statement with the xtable function(library xtable). I'm trying to get the printing of the elements of two lists in a sorted way. These two list have in common the their names. I will try to give an example: the first list looks like this: $code1 Code code1 Nation

Dear all, I have a dataset as below: id code1 code2 p 1 4 8 0.1 1 5 7 0.9 2 1 8 0.4 2 6 2 0.2 2 4 3 0.6 3 5 6 0.7 3 7 5 0.9 I just want to rewrite it as this (vertical to horizontal): id var1 var2 var3

Hello! I am wondering if it's possible to run - in sequence - code that is stored in several R scripts. For example: Script in the file "code1.r" contains the code: a = 3; b = 5; c = a + b Script in the file "code2.r" contains the code: d = 10; e = d - c Script in the file "code3.r" contains the code: result=e/a I understand that I could write those 3 scripts

Hello - I am making a first attempt at writing a simple C++ routine to print out R objects (this is a simple proof-of-concept as part of a larger package development). The relevant C++ routine is as follows: void Rwrite(SEXP fd, SEXP msg) { int *ofd = INTEGER(fd); const char * omsg = CHAR(asChar(msg)); printf("[%i] %s",*ofd,omsg); } And the corresponding interface in R is as

Dear R-users, I would like to have some advises about a problem illustrated by the following snippet. Within myf, I need to evaluate a piece of R code that is passed as a character argument and then return the objects that are created by this code. The difficulty comes from the fact that the content of the code is variable and unknown to me (obviously not in this illustration!). With the

I am writing an interprocedural compiler pass. Because the passneeds information from a FunctionPass, e.g., the post-dominance frontier (PDF), and because a ModulePass is not permitted to require a FunctionPass, I am forced to make my pass a FunctionPass and do majority of its work in the doFinalization() method. When I run "opt -mypass -verify -o code2.bc code1.bc" I get no

I followed what you said and called verifyModule() with the AbortProcessAction option. verifyModule() returns false, but does not abort and does not print out any information about what caused the verification to fail.

I also tried iterating through the functions of the module and calling verifyFunction(), which also returns false, but does not cause an abort or report anything to stderr about what caused the verification to fail. From the doxygen for verifyFunction() and verifyModule(), it seems like they both should print information to stderr if the verification fails and should abort opt if

I am receiving this error running a command on a multi-row data-frame. The data is strings of text (each with new line separator, no spaces, no numerical characters). Error in FUN(X[[1L]], ...) : STRING_ELT() can only be applied to a 'character vector', not a 'integer' I can run single text string into the same command, and so the issue seems to be how the package deals with the

I have a daily job that attaches hundreds of pseudo-packages containing data as promise objects (DDP's, ref: g.data package), and plots the results to a multi-page pdf device. Sometimes it fails. Under R-2.2.1 it just gave segfaults. Under R-2.3.1 it gave this error message: *** caught segfault *** address (nil), cause 'memory not mapped' Traceback: 1:

Dear list, I?m having a little trouble with adding vertical lines to a histogram. I need to draw a matrix of histograms (using facets), and in each histogram add a vertical line indicating the mean value of the data in each facet. According to the last example in the geom_hline help, to display different lines in each facet I need to provide a data frame. I modified this example to make a plot

I think I misread the doxygen. verifyFunction & verifyModule return false if no errors are detected. However, my question now becomes why does the code produced by my transform pass verification, but it causes an assertion failure in the byte reader when it (the code produced by my transform) is passed to another invocation of opt?

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

Greetings. I'm having some trouble constructing a contingency table from raw data (actually read in via RPgSQL). Here's the deal: - What I've got: a data frame in the form: Groupcode code1 code2 code3 code4 code5 .. coden where groupcode is one of {P,C,B,S,U,X} and code{1..n} is TRUE or FALSE. code{1..n} are NOT mutually exclusive, so between 0 and n of them can be TRUE. -

Hi, I have an S4 class directly derived from 'array' as shown in the code below (EBImage package of Bioconductor 2.1, devel), it simply contains array adding a couple of slots: setClass ("Image", representation (colormode="integer", filename="character", compression="character", resolution="numeric", features="list" ),

Hello, in "Writing R Extensions" I found the following stuff: "Note that these coercion functions are not the same as calling as.numeric (and so on) in R code, as they do not dispatch on the class of the object. Thus it is normally preferable to do the coercion in the calling R code." ( Writing R Extensions, 2011-04-13, page 100 ) What is meant by
