  4. For additional tests, modify the functions c2, c3, c4, c5 in the file user_defined.c.

 

R function:

  1. Write an R function with 4 input arguments, where argument 1 is the vector of delta values, argument 2 is the covariance matrix, argument 3 is the correlation matrix, and argument 4 is the inverse correlation matrix.
    Example: fnc1 <- function(delta, cov, cor, invcor) { return(sum(delta*delta)) }
  2. In the options list for the crave function, set the option user_func to the name of the function.
    Example: crave(geno_file, pheno_file, out_file, op=list(user_func="fnc1"))
  3. For additional tests, set the option user_func to be a vector of function names.
