I not uncommonly have the following paradym fits <- lapply(argument, function)
resulting in a list of function results. Often, the outer call is to mclapply, and the function encodes some long calculation, e.g. multiple chains in an MCMC. Assume for illustration that each function returns a list with elements beta, loglik, iter. Then sapply(fits, function(x) x$iter) will give me a vector, with the number of iterations used by each instance. I've often been suspicious that there is some simple shorthand for the "grab all the elements named iter" that skips the explicit x$iter function. Am I indeed overlooking something? I don't expect a speed increase, just cleaner code.
