main/character.c (et.al): dangerous AllocBuffer()
I was hit by ugly crashes of R, when I tried to read big data sets ("volcano"). So I looked into the code and found the following in character.c (triggered by substr()): I assume that the helper function AllocBuffer() shall facilitate an economic memory management. But the use of realloc() in the else-branch does not conform to ANSI and may hit you with certain compilers. When called

postscript preview
gday R friends, I was wondering if anyone could help me with some graphics issues please. I'm processing R in batch on redhat6.2 with some graphics to be imported into msword on NT. For scaling within my doco I want some vector type graphics. win.metafile doesn't seem to be supported on redhat which gives me postscript. postscript is ideal but doesn't contain a preview so I

Looking for R_Home ...
This is my first question to this list and possibly a bit dumb, but anyway: Can anybody tell me, where, e.g. in the "unix" reference release a DEFINITION of char * R_Home can be found? Via Defn.h the "extern" DECLARATION is everywhere, but when I derived a somewhat other main() program my linker complained about the missing definition. Thomas Hoffmann.

formatReal()-bug (or Is there anybody out there w/o IEEE754?)
On a system with IEEE_754 undefined, I run into an bug, when the value of an element of the first argument (e.g., x[0]) of formatReal() is NA: 1. (format.c:235) if (!R_FINITE ..) gives nanflag=1 (!naflag remains 0) 2. (format.c:272..288) *m gets an value of -2147483643 (from the format fiddling, should not matter to us) 3. (format.c:289) because naflag is zero, m does not

Conditional for XDR code left out in saveload.c (PR#478)
Full_Name: Thomas Hoffmann Version: 1.0.0 OS: OS/2 Warp 4.0 FP 11 Submission from: (NULL) (141.30.125.20) I autoconfigured/configured the src'es w/o having XDR (#undef HAVE_RPC_XDR_H). In saveload.c , at the beginning of the file the XDR code is enclosed by matching #ifdefs. But in the NEW_SAVE_FORMAT section, there are no #ifdefs around the XDR code. Does this imply that using the new

R_OpenSiteFile: Do not use a null ptr as filename in fopen (PR#312)
I get crashes when I call R without any arguments and having no environment variables R_PROFILE and RPROFILE. The reason is, that in unix/sys-common.c in R_OpenSiteFile() fopen is called with a null ptr as filename (because this is the outcome of getenv()). Although most compilers seem to interpret this as "file not found", this is an undefined behavior concerning to all C standards

PICT output?
hi, all. I use R on a unix (linux) box and am quite happy with it. However, sometimes I need to create a graph that needs to be used with Microsoft Word or Powerpoint (ug). I can create a png or jpeg format picture, but the text look pretty crummy because jpeg is bitmapped. I can also create a PS/EPS version (my preference), but then it doesn't display properly in word or powerpoint (but it
