I'd appreciate all help.... I am

Hello all, I wrote a function with many arguments. Then I need to call it many times with changes on some arguments only. Is there any way to write a function or have a method to "update" it, like the relationship between lm() and update()?

An apparatus exists whereby a collection of balls is displaced to the top of a stack by suction. A top level (Level 1) each ball is shifted 1 unit to the left or 1 unit to the right at random with equal probability. The ball then drops down to level 2. At Level 2, each ball is again shifted 1 unit to the left or 1 unit to the right at random. The process continues for 15 levels and the balls are

I think what's been missed is that zapsmall works relative to the absolute largest value in the vector. Hence if there's only one item in the vector, it is the largest, so its not zapped. The function's raison d'etre isn't to replace absolutely small values, but small values relative to the largest. Hence a vector of similar tiny values doesn't get zapped. Maybe the line
