this question has answer here: is there way pass optional parameters function? 5 answers i define function takes 2 arguments, possibility of third. i'm isn't possible, considering built-in range function has: range(stop) -> range object range(start, stop[, step]) -> range object maybe it's possible? or maybe have wrong idea because range immutable sequence type? for clarity's sake, same function example(x,y) run example(x,y,z) def example(x, y, z=none): if z none: return x + y else: return x + y + z then >>> example(3, 4) 7 >>> example(3, 4, 5) 12

this simple solve. have 2d matrix mat 500 rows × 335 columns, , data.frame dat 120425 rows. data.frame dat has 2 columns i , j , integers index row, column mat . add values mat rows of dat . here conceptual fail: > dat$matval <- mat[dat$i, dat$j] error: cannot allocate vector of length 1617278737 (i using r 2.13.1 on win32). digging bit deeper, see i'm misusing matrix indexing, appears i'm getting sub-matrix of mat , , not single-dimension array of values expected, i.e.: > str(mat[dat$i[1:100], dat$j[1:100]]) int [1:100, 1:100] 20 1 1 1 20 1 1 1 1 1 ... i expecting int [1:100] 20 1 1 1 20 1 1 1 1 1 ... . correct way index 2d matrix using indices of row, column values? almost. needs offered "[" 2 column matrix: dat$matval <- mat[ cbind(dat$i, dat$j) ] # should it. there caveat: although works dataframes, first coerced matrix-class , if non-numeric, entire matrix becomes "lowest denominator" class.

i found explicit invocation of e.fillinstacktrace() directly after creation of exception exception e = new exception() . i think redundant, because constructor of throwable invoke fillinstacktrace() . but maybe overlooked , lines useful: exception e = new exception(); e.fillinstacktrace(); creationinfo = new creationinfo(e.getstacktrace()); ( public creationinfo(stacktraceelement[] astacktrace){...} ) i think the additional invocation of e.fillinstacktrace(); directly after creation exception redundant , wast lot of resource, because method expensive. it seams construct needed obtain current stacktrace, therefore: creationinfo = thread.currentthread().getstacktrace(); is better way. before filling issue report want ask if have overlooked something? you correct on both counts: biggest reason why fillinstacktrace available let override in own exceptions you'd save costs of providing stack trace information, or need hide information location excep...
