[R] How do you exit a function in R?

[ctu at bigred.unl.edu]

You might try to use "on.exit" or "stop"?

# on.exit
if (nAssetPositions != nAssetPrices) {
                on.exit(cat("Different number of assets! "\n"))
     }

# stop
if (nAssetPositions != nAssetPrices) {
                stop("Different number of assets!")
     }

You could find these in "S programming" by W.N Venables and B.D. Ripley
