Re: [R] find index in a list of list

Since the offered solution already checks each top level element using the "identical" function, you just need a different comparison function, like perhaps: mycompare <- function( x, y ) { identical( x[[ "a" ]], y[[ "a" ]] ) && identical( x[[ "b" ]], y[[ "b" ]] ) } Note that your decision

Re: [R] nls fitting & plotting to data subsets defined by combinations of categorical variables

Given that nls() often gives failures of the "singular gradient" type, you may want to give package nlsr a try with the nlxb() function. It should be able to use analytic gradients on this expression, has bounds, and uses a Marquardt stabilized solver. It can still fail, but is more robust than

I think Bert's advice is sound. Let me add a few, miscellaneous comments: (1) Some people find "by" easier than "tapply". (2) The "apply" function can, as I'm sure you (Bert) know, iterate over a matrix. (3) Hadley probably has better ways to do all of this (it's hard to keep up). -- Mike On
