Creating LB_lengths objects from data inside R about lbspr HOT 5 CLOSED

I'm not clear on the problem. Can you expand on it with a reproducible example of what you mean?

The recommended approach to creating LB_lengths objects in R is:

LenData <- new('LB_lengths', verbose=FALSE)
LenData@LMids <- LenMids
LenData@LData <- LengthComps
etc

from lbspr.

I would expect new() to take any named object passed to it and place it in the right slot. So

LenData <- new('LB_lengths', verbose=FALSE, LMids=seq(1,10))

should place that vector in LMids

> LenData@LMids
logical(0)

Our MSE code, for example, parses various objects and then constructs a list to then call new, or the creator function if available, using do.call. So being able to construct an object on a single command is quite useful. I am writing a creator function to use there, but I thought it could be something worth considering.

This can be resolved by creating a wrapper function, eg:

LB_lengths <- function(LMids, etc) {
  Obj <- new('LB_lengths', verbose=FALSE)
  Obj@LMids <- LMids
  etc
  Obj
}

I'll consider adding to the package sometime, but as it isn't under active development it's probably easiest if you write the wrapper function in your own code

Sure, no need to worry about it if the package is not being developed further. What I have is

LB_lengths <- function(...) {
  args <- list(...)
  res <- new('LB_lengths', verbose=FALSE)
  for(i in names(args))
    slot(res, i) <- args[[i]]
  return(res)
}

Sounds good. I'll incorporate in the package at some stage when I do an update.
