...ter halting the program: (gdb) p R_PV(colNames) does not show the content of colNames. I am positive my code is right because if I insert "PrintValue(colNames);" in the c code, it will print the right value. My debug result shows that the variable "colNames" failed the "isObject" call. I am not sure whether this is a new feature or bug. Anyone can help? Thanks, Gang Liang

...t; as.environment( a ) Erreur dans list(NULL, list(aa = function (n, mean = 0, sd = 1) : correspondance partielle de cha?nes de caract?res incorrecte Is it because the call made by lang4 is not protected while evaluated in this line : case VECSXP: { /* implement as.environment.list() {isObject(.) is false for a list} */ return(eval(lang4(install("list2env"), arg, /*envir = */R_NilValue, /* parent = */R_EmptyEnv), rho)); } (BTW, this was detected in a looooooooong Rcpp-devel thread.

...- Load that requires tagged value encoding and that an object to have a particular shape and involves a doubly-indirected object model (for example when implementing dynamic language heap accesses): %object = inttoptr %value %p1 = getelementptr %object, <things> %p2 = load %p1 !notrap !{ @isObject, %value } %p3 = getelementptr %p3, <more things> %v = load %p3 !notrap !{ @hasShape, %object, 0xstuff } // 0xstuff will be a compile-time constant I can’t think of any examples where you’d want to use safe-to-execute and where Hal’s rule won’t hold. -Filip > > -Hal > >>...

Why does as.numeric convert matrices and arrays to vectors? as.numeric(matrix(c("1", "2", "3", "4"), 2, 2)) [1] 1 2 3 4 I could only figure out ugly ways to bypass this, like: x <- matrix(c("1", "2", "3", "4"), 2, 2) array(as.numeric(x), dim = dim(x), dimnames = dimnames(x)) Alberto Monteiro

...an unprotected SEXP in <R>/src/main/envir.c, in the function do_as_environment(), case VECSXP of the switch. Here is modified code that seems to fix the problem, at least under Linux: case VECSXP: { Rprintf("VECSXP as.environment\n"); /* implement as.environment.list() {isObject(.) is false for a list} */ SEXP sp = PROTECT(lang4(install("list2env"), arg, /*envir = */R_NilValue, /* parent = */R_EmptyEnv)); SEXP res = eval(sp, rho); UNPROTECT(1); return res; } Dominick > Romain > > > -- > Romain Francois > Pr...

Hi, Starting with ordinary vectors, so we know what to expect: > mapply(function(x, y) {x * y}, 101:106, rep(1:3, 2)) [1] 101 204 309 104 210 318 > mapply(function(x, y) {x * y}, 101:106, 1:3) [1] 101 204 309 104 210 318 Now with an S4 object: setClass("A", representation(aa="integer")) a <- new("A", aa=101:106) > length(a)
