make_eof_ram converts SEM arrow notation to ram describing SEM parameters
Arguments
- times
A character vector listing the set of times in order
- variables
A character vector listing the set of variables
- n_eof
Number of EOF modes of variability to estimate
- remove_na
Boolean indicating whether to remove NA values from RAM (default) or not.
remove_NA=FALSEmight be useful for exploration and diagnostics for advanced users- standard_deviations
One of
"equal","unequal", or a numeric vector indicating fixed values.
Examples
# Two EOFs for two variables
make_eof_ram( times = 2010:2020, variables = c("pollock","cod"), n_eof=2 )
