Run SPM Analysis in a Specific Directory

This function runs a Stock Production Model (SPM) analysis in the specified directory. The function changes the working directory to `dirname`, runs the SPM analysis, and then reads the results from `spm_detail.csv`. It returns to the original working directory after completing the analysis.

Usage

runSPM(dirname, ctrl = NULL, run = FALSE, engine = c("admb", "rtmb"))

Arguments

dirname

A string specifying the directory in which to run the SPM analysis.

ctrl

Optional control settings for the SPM analysis. If NULL, default settings are used.

run

Logical. If TRUE, the SPM analysis is run. If FALSE, the function only reads the results from `spm_detail.csv`.

engine

Model backend to use. `"admb"` runs or reads the legacy SPM implementation; `"rtmb"` uses the experimental R implementation.

Value

An `spm_result` data frame containing standardized projection results. Existing model-specific columns are preserved.

Examples

if (FALSE) { # \dontrun{
runSPM("examples/atka")
} # }
