Hello! I am having some trouble with some list output.
Here is my code: geobunch <- function(y) { out <- vector("list",3) aic <- numeric(length=3) print(str(out)) for(i in 1:3) { x <- geomin(y,i) print(i) print(x) print(str(x)) out[i]$phi_0 <- x$phi_0 out[i]$maxlike <- x$maxlike out[i]$bigp <- x$bigp aic[i] <- -2*out[i]$maxlike + (2*(i+1)) } minaic <- which(aic==min(aic)) minout <- out[unlist(minaic)] return(minout) } And here is the output: > geobunch(ez2a) List of 3 $ : NULL $ : NULL $ : NULL NULL [1] 1 $phi_0 [1] 2.856428 $bigp [1] 0.1584016 $maxlike [1] -473.0203 List of 3 $ phi_0 : num 2.86 $ bigp : num 0.158 $ maxlike: num -473 NULL Error in aic[i] <- -2 * out[i]$maxlike + (2 * (i + 1)) : replacement has length zero In addition: Warning messages: 1: In out[i]$phi_0 <- x$phi_0 : number of items to replace is not a multiple of replacement length 2: In out[i]$maxlike <- x$maxlike : number of items to replace is not a multiple of replacement length 3: In out[i]$bigp <- x$bigp : number of items to replace is not a multiple of replacement length > I know that the problem is in how I am setting up the "out" variable, but I'm not sure how to correct it. Also, the bigp variable can take on different lengths. This is on R version 3.1.3, on Ubuntu 14.04. Thank you so much for any help.
