Remove Objects From Memory By Name And Type

Description

Remove objects by name or type to free up memory. Uses the base rm() function but provides more flexible ways to remove objects.

Usage

free_memory(names = NULL, types = NULL, envir = .GlobalEnv)

Arguments

names	Object names to be removed.
types	Object types to be removed.
envir	The environment to remove the objects from.

Details

free_memory() is based on the 'SAS' function Proc Datasets. Among other things this procedure is able to remove datasets from memory. But not only by writing out the full file name, it is capable of looking for datasets starting with, ending with or containing a certain text. Additionally certain object types can be removed.

Value

Returns removed objects.

Examples

# Example data frames
my_data1 <- dummy_data(10)
my_data2 <- dummy_data(10)
data     <- dummy_data(10)
file     <- dummy_data(10)

# Free memory by name
free_memory("my_:")
free_memory(c("data", "file"))

# Free by type
my_data1 <- dummy_data(10)
my_data2 <- dummy_data(10)
data     <- dummy_data(10)
file     <- dummy_data(10)

free_memory(type = "data.frame")
