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.
