...d by one or more observers. Thus the data are a lower-triangular array AxB where each cell [i,j] has a zero or one indicating whether observer i saw event j. I am interested in how observers cluster in circuits whereby observer _a_ sees events _1,2,3_, observer _b_ sees events _2,4,5_, observer _c_ sees event _4_, and observer _d_ sees _4,6,7_. Observers a, b, c, d comprise a circuit linked by the events they jointly observed. Given AxB, how can we use R to articulate the circuits? Pseudocode for my SQL solution is below. For each observation i: - get all the events [j1,j2,...jk] obs...

I've lived by the mantra since that you can never > trust a pointer in R code. User must always check for NULL. In _C_ code. This is true whether you are calling into the R C API or any other C library: you as the C programmer need to make sure either that passing NULL is OK or make sure you don't do that. I wouldn't object to mkXXX checking for NULL and signaling an error instead of segfaulting, but good...

I am trying to use the R API to call optim functions (nmmin, vmmin, lbfgsb, etc.) through a C program but I couldn't find the shared library to link under the R-2.6.0 build which is compiled under Linux (REL5). main.cpp:35: undefined reference to `Rf_initEmbeddedR(int, char**)' main.cpp:41: undefined reference to `nmmin' Thanks in advance for any help. ------------------------
