Usage

maxent_save_lambdas(featured_space, file)

Arguments

featured_space

External pointer to a trained FeaturedSpace object.

file

Character: path to the output file.

Examples

# \donttest{
n   <- 50L
idx <- c(5L, 15L, 25L, 35L, 45L)
env <- list(bio1 = runif(n), bio12 = runif(n))
feats <- maxent_generate_features(env, types = "linear")
fs  <- maxent_featured_space(n, idx, feats)
maxent_fit(fs, max_iter = 100)
