...attributes. This is exactly what an example in the R Extensions manual section 4.11.2 "Inspecting R objects when debugging" does, but the code there doesn't work, presumably because the R internals have changed since it was written. Specifically, I get (gdb) p $a->u.listsxp.tagval->u.symsxp.pname->u.vecsxp.type.c Error: There is no member named vecsxp. where $a was set to be the attrib member of an SEXP. Could someone let me know what needs to be fixed for this to work? I imagine it's a typecast, but I haven't been able to put it together. (An example usin...

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 All, Well I finally have found the time to get svn working and I have successfully built my own tuned atlas (multi-threaded version) libs and have both the r-devel and r-patched trees building daily on my box. The problem is I still do not have a good idea of the layout and design of R, and typically I "learn by doing" by trying to fix a bug that hits me. Unfortunately ;-)

Dear all, It seems that textConnection() can trigger a segmentation fault. The following script (using two large loops) makes this bug reproducible: for (i in 1:10000) { z=textConnection(NULL,open='w') for (j in 1:100) { write(runif(1)*1e6,file=z) write('\n',file=z) } close(z) } The bug could be reproduced on R-2.6.1, R-2.7.0 and on the latest R-devel
