pub unsafe fn Rf_dnorm4(x: f64, mu: f64, sigma: f64, give_log: c_int) -> f64Expand description
Normal density: dnorm(x, mean = mu, sd = sigma, log = give_log).
Rf_dnorm4 from Rmath.h (the dnorm and dnorm4 macros resolve
to it). A non-zero give_log returns the log density.
§R conditions
An invalid sigma (negative) returns NaN without a warning: nmath
does not report domain errors, and the “NaNs produced” warning that
stats::dnorm gives comes from R’s vectorised wrapper. nmath reports
other problems (precision loss, non-convergence) through R’s
warning(), and under options(warn = 2) a warning becomes an R
error, which longjmps. Call this where such a longjmp is caught: a
#[miniextendr] function body, or
with_r_unwind_protect.
#[r_ffi_checked] gives thread routing and checking only, not an
unwind guard.
Checked wrapper for Rf_dnorm4. Calls Rf_dnorm4_unchecked and routes through with_r_thread.
