[R] Reducing a list of functions by composition fails

Hi All, I'd like to be able to specify the ordered composition of several functions. So I defined compose: compose - function(f,g){ function(x){f(g(x))} } and some simple test functions: plus2 - function(x){x+2} plus3 - function(x){x+3} plus4 - function(x){x+4}

Re: [R] regression analysis with interactions

Thank you very much for your kind reply, I have found that the error was in the stdCoeff function and not in the linear model. summary() works pretty well on my model, I will simply use another function to compute my coefficients. Best regards, Jennifer Date: Wed, 4 Aug 2010 15:27:40 -0500

Assigning the value directly to result[i] would give a null to result. Like that: result[[i]]-taxondiveO(abd,taxa) result[[i]]-as.data.frame(result[[i]])[1,] In fact your code's result should have null elements in it. You lost your nulls through do.call process. I can't find a way to assign

I sometimes have to work with vectors/matrices with 2^31 - 1 elements. I have found the bigmemory package to be of great help. My lab is also going to learn sqldf package for getting bits of big data into/out of R. Learning both of those packages should help you work with large datasets in R.
