Re: [R] creating a dynamic output vector

Here is a script that will find all the atomic objects of length 1 and put them in a dataframe that you then use to determine what variables are there. > a <- 1 # generate some atomic objects > b <- 1.3 > x.char <- "character string" > x.log <- TRUE > x.real <- pi > # get all atomic objects of l

Re: [R] creating a dynamic output vector

Everyone is assuming I know what the output data are, or that they come out from my model in some easily called vector. But I don't, and they do not. The outputs are hidden, and all are separate variables that need to be called. Also which ones come out after a given run will vary each time. Al

Re: [R] creating a dynamic output vector

Here is a function that might do what you want: > # function to create the output > f.output <- function(dat){ + # create the base output vector + output.base <- rep(NA,10) + names(output.base) <- paste("var", 1:10, sep='') + output.base[names(dat)] <- dat + output.base + } > >

Re: [R] Aggregate with non-scalar function

Yes, that's exactly it! Many thanks, it all comes back to me now! It's the darn do.call that I can never remember somehow. I know I've reinvented this wheel several times -- you'd think I'd learn. Sigh. Again, my thanks! Regards, Mike On Nov 7, 2007 2:35 PM, jim holtman <[EMAIL PROTECTED]>

[R] a newbie question about "data"

hi, I am reading Modern Applied Statistics with S 4th ed。 page4 have these two lines: > library(MASS) > data(chem) # needed in R only but I find withou the line " data(chem)" I can still access chem, isn't it? is it unnecessary or something i missed here? thanks for the replay in advance. ___
