optimize simultaneously two binomials inequalities using nlm( ) or optim( )
Dear R users, I?m trying to optimize simultaneously two binomials inequalities (used in acceptance sampling) which are nonlinear solution, so there is no simple direct solution. Please, let me explain shortly the the problem and the question as following. The objective is to obtain the smallest value of 'n' (sample size) satisfying both inequalities: (1-alpha) <= pbinom(c, n, p1)

you are right about the 3rd line but it doesn't help me for my problem.

Advanced bootstrap question
I have an advanced question about bootstrapping. There are two datasets. In each bootstrap iteration, I would like to sample One observation per cluster from the first dataset. N observations with replacement from the second dataset. Right now I am using dplyr::sample_n() for first dataset, with this sampling embedded in the program that boot() from the boot package is running to sample the

Frequency vector
I want to create a vecor with frequencies. I have tried this: a <- c(1,1,1,1,2,3,4,5,5) b <- table(a) print (b[1]) which results in: > print (b[1]) 1 4 The only thing I want is the 4. So this seems obvious: print (b[1,2]) but it does not work: Error in b[1, 2] : incorrect number of dimensions How do I get a vector or how do I refer to the "4" without getting the

segfault calling SDL_Init with FFI/ MCJIT
I'm getting a segfault when I call `SDL_Init( SDL_INIT_VIDEO )` within the MCJIT.  If I compile the same program to an EXE I don't have a problem. Are there any general restrictions, or known issues, with loading a library like SDL2 via the MCJIT?  (LLVM-3.8 still) The stack trace, from GDB, is below. I noticed the error actually happens deep inside a transitively loaded GL drive module,
