R Language Using debug


Example

You can set any function for debugging with debug.

debug(mean)
mean(1:3)

All subsequent calls to the function will enter debugging mode. You can disable this behavior with undebug.

undebug(mean)
mean(1:3)

If you know you only want to enter the debugging mode of a function once, consider the use of debugonce.

debugonce(mean)
mean(1:3)
mean(1:3)
