I wondered the same thing a few days ago.
https://stackoverflow.com/questions/36966036/how-to-get-the-last-error
The here's the solution from that discussion:
get_last_error <- function()
{
tr <- .traceback()
if(length(tr) == 0)
{
return(NULL)
}
tryCatch(eval(parse(text = tr[[1]])), error = identity)
}
Note that it uses .traceback() from R 3.3.0; you'll have to use
baseenv()$.Traceback with earlier version of R.
