make_eof_ram function

Make a RAM (Reticular Action Model)

make_eof_ram converts SEM arrow notation to ram describing SEM parameters

make_eof_ram(
  times,
  variables,
  n_eof,
  remove_na = TRUE,
  standard_deviations = "unequal"
)

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=FALSE might be useful for exploration and diagnostics for advanced users
• standard_deviations: One of "equal", "unequal", or a numeric vector indicating fixed values.

Returns

A reticular action module (RAM) describing dependencies

Examples

# Two EOFs for two variables
make_eof_ram( times = 2010:2020, variables = c("pollock","cod"), n_eof=2 )
