memory.limit
Memory Limit and Size
Description
Retrieves the maximum total allocated space and the total allocated space,
or increases the memory maximum limits. (Both options are specific to Microsoft Windows.)
Usage
memory.limit(size = NA)
memory.size(max = FALSE)
Arguments
| size |
a numeric value specifying the new maximum memory use allowed (in megabytes).
NA retrieves the current memory limit(in megabytes).
|
| max |
a logical value. If TRUE, returns from the operating system the maximum of
total allocated space. If FALSE (the default), returns the current total allocated
space (that is, memory in use).
|
Details
If size is a numeric value, and not NA, memory.limit specifies a new
memory limit (in megabytes). If size is less than the previous memory limit,
a warning is given.
memory.size gets the allocated memory space--either the maximum or the memory
currently in use--depending on the value of the max argument.
Value
| memory.limit |
returns an integer value giving the current maximum memory use allowed (in megabytes).
|
| memory.size |
returns the maximum total allocated memory or total memory in use (in megabytes).
