# Check if packages are available
required <- c("ggplot2", "dplyr")
availability <- check_deps(required)
print(availability)
#> ggplot2   dplyr 
#>    TRUE    TRUE 

# Get suggestions for missing packages
required_with_missing <- c("ggplot2", "dplyr", "nonexistent_package")
availability <- check_deps(required_with_missing, install_missing = TRUE)
#> Missing packages detected: nonexistent_package
#> To install missing packages, run:
#> install.packages(c("nonexistent_package"))
print(availability)
#>             ggplot2               dplyr nonexistent_package 
#>                TRUE                TRUE               FALSE
