Having a hard time understanding the help files for tryCatch. Looking for a
little help with the following statement which sits inside a for loop
zest[i] <- tryCatch(sapply(getNodeSet(zdoc, "//zestimate/amount"),
xmlValue), error=function() zest[i] <-"NA")
zest is a numeric vector
If the sapply statement evaluates to an error, I'd like to set the value of
zest[i] to NA and continue with the loop.
