get_ram: Get Memory Size

Description

Get Memory Size

Usage

get_ram()

Value

System RAM in bytes, or NA if not supported.

Details

The function get_ram only supports 'MacOS', 'Windows', and 'Linux'. 'Solaris' or other platforms will return NA. Here are the system commands used to detect memory limits:

'Windows'

Uses command 'wmic.exe' in the 'Windows' system folder. Notice this command-line tool might not exist on all 'Windows' machines. get_ram will return NA if it cannot locate the command-line tool.

'MacOS'

Uses command 'sysctl' located at '/usr/sbin/' or '/sbin/'. Alternatively, you can edit the environment variable 'PATH' to include the command-line tools if 'sysctl' is missing. get_ram will return NA if it cannot locate 'sysctl'.

'Linux'

Uses the file '/proc/meminfo', possibly the first entry 'MemTotal'. If the file is missing or entry 'MemTotal' cannot be located, get_ram will return NA.

Examples

# NOT RUN {
get_ram()

# }
