parent

parent environment to set for the new environment. Defaults to the parent environment of envir.

Examples

# Make a new environment with the object 'key'
envir <- new.env()
envir$key <- "value"
"key" %in% ls() # FALSE
#> [1] FALSE
"key" %in% ls(envir = envir) # TRUE
#> [1] TRUE

# Duplicate the envir and show it contains 'key'
new_envir <- duplicate_env(envir)
"key" %in% ls(envir = new_envir) # TRUE
#> [1] TRUE
