Dear R-dev list, I wonder if stats::integrate shouldn't warn the user when a numeric vector of length > 1 is passed as lower or upper bounds. If a vector is passed, only the first value is used and the others are silently ignored:
integrate(sin, lower=0, upper=pi) integrate(sin, lower=0:10, upper=pi) ?integrate doesn't appear to mention explicitly that the function is not vectorised over those arguments. It's probably not a common mistake, but it can have unfortunate consequences in the iterative calculation of multiple integrals. Someone was puzzled by this today (http://stackoverflow.com/q/36275909/471093) and it wasn't immediately obvious what had led to incorrect results (and worse, it could have gone unnoticed).
