I tried, but seemed not to work. For example, when I run a command as below: c++filt _ZNSt4listIiSaIiEEaSERKS1_ The output remains the same as the input symbol. By the way,

Hi, I have the following code from Splus that I'd like to migrate to R. So far, the only problem is the arima.filt function. This function allows me to filter an existing time-series through a previously estimated arima model, and obtain the residuals for further use. Here's the Splus code: # x is the estimation time series, new.infl is a timeseries that contains new information # a.mle

I have encountered a need for manually generating the mangled name of an arbitrary C++ function. The only way I currently know how to do this is to generate a dummy C++ source file, compile it, and look at the output. This approach is so ugly that I would like for it never to see the light of day. The c++filt tool generates demangled C++ names given the mangled ones, which is the opposite

Dear R-helpers: (this is part of a bigger program) the following fails as a function, but runs OK if we comment out the fnfn_ function() line. Any hint would be appreciated. -Yudi- R : Copyright 1998, The R Development Core Team Version 0.63.0 Beta (Nov 13, 1998) -- on WIndows3.11 fnfn _ function (m=10,n=10,spar=2) { fn _ function(u,v){ uc_ u-floor(m/2)-1 vc_ v-floor(n/2)-1

Hi R-users, I'm trying to produce decompositions of a multiple time-series, grouped by a factor (called "area"). I'm modifying the code in the STLperArea function of package ndvits, as this function only plots produces stl plots, it does not return the underlying data. I want to extract the trend component of each decomposition ("x$time.series[,trend]), assign a name

Hi given an ARMA process and the AR and MA coefficients I need the residuals. arima() calculates the residuals together with the best AR and MA coefficients, but I need the coefficients to take known values. In S-PLUS there is a function arima.filt(). Is there something similar in R? Thanks for any help, Matthias Budinger

Hi, I have a question about the IR model for SEH filters (as I want to use the same model for CLR filters). In particular, when an outer filter is invoked before entering an inner finally, which piece of IR reflects the filter's side-effects? To take a concrete example, consider this C code: void foo() { int x; __try { x = 0; __try { x = 2; may_throw(); }

Are you making use of RTTI? Ciao, Duncan.

Hi, I am looking for a way to get unmangled subprogram names from a DWARFContext. The name I want is available in the attribute `DW_AT_name` [1], but as far as I can tell this is only returned as a fallback in `DWARFDebugInfoEntryMinimal::getSubroutineName` when the linkage name is not available [2]. If this is not currently possible, is there any interest in adding such access to the public

Hi, Lately LLVM has been adding -fno-rtti to most of the compiler. I have a pass which uses LoopPass and which inherits from FunctionPass and a class of my own. If I compile my code with ENABLE_RTTI=1, I can't dynamically load the shared object since it won't be able to find the symbol for LoopPass's typeinfo. undefined symbol: _ZTIN4llvm8LoopPassE $ c++filt _ZTIN4llvm8LoopPassE

After decoding the unresolved symbols from wxruby2.so using c++filt, and comparing with the symbols provided by wxGTK, it became clear that wxGTK was using wchar_t whereas wxruby2.so was using char. So I rebuilt wxGTK, turning off unicode. That worked. No more unresolved symbols. What gives? Should the wxruby code have been built using wchar_t, and if so, how? However, now I get the
