get_memory_thresholds: Get dynamic memory thresholds based on system RAM

Description

Calculates appropriate memory thresholds for conversions based on total system RAM. Returns conservative values suitable for most systems.

Usage

get_memory_thresholds(total_ram = NULL)

Value

Named list with thresholds in MB:

silent

Size below which conversions happen silently

warning

Size requiring user confirmation

force

Size requiring force=TRUE

blocked

Size that cannot be converted

Arguments

total_ram

Numeric. Total system RAM in GB. If NULL (default), auto-detects using C++ implementation.

Details

Calculation logic:

Uses percentage of total RAM with safety margins:

• Silent: 15\

• Warning: 30\

• Force: 50\

• Blocked: 80\

Fallback values (if RAM detection fails):

• Silent: 2 GB

• Warning: 4 GB

• Force: 8 GB

• Blocked: 16 GB

Examples

# \donttest{
# Auto-detect
thresholds <- get_memory_thresholds()
# $silent: 3000 MB, $warning: 8000 MB, etc.

# Manual specification (e.g., for 32GB system)
thresholds <- get_memory_thresholds(total_ram = 32)
