Debugging lapply/sapply calls

Question

Code written using lapply and friends is usually easier on the eyes and more Rish than loops. I love lapply just as much as the next guy, but how do I debug it when things

Answer 1

You can debug() the function, or put a browser() inside the body. This is only particularly useful if you don't have a gajillion iterations to work through.

Also, I've not personally done this, but I suspect you could put a browser() in as part of a tryCatch(), such that when the error is generated you can use the browser() interface.
