Trouble embedding functions (e.g., deltaMethod) in other functions
...mbda")$SE
}
mod.SE
This code executes deltaMethod() flawlessly (NOTE: [[1]] and [[10]] are
supposed to be NaN's). However, my goal is to embed the deltaMethod inside
another function I'm writing. For brevity's sake, here's a very simple
example that produces the same problem.
deltaSE <- function(mod, x){
mod.SE <- list()
for(i in 1:length(xVal)){
z <- xVal[i]
mod.SE[[i]] <- deltaMethod(mod, "(m0^(1/lambda) - (z *
m0/t0)^(1/lambda))^lambda")$SE
}
mod.SE
}
deltaSE(nlls, xVal)
deltaMethod, when embedded in my deltaSE function produces only NaN's...
