Examples

# Simple usage:
conan::conan_check(c("conan", "pkgdepends"), .libPaths())
#> $complete
#> [1] TRUE
#> 
#> $found
#> [1] "conan"      "pkgdepends"
#> 
#> $missing
#> character(0)
#> 

# While we parse references, we don't check version information:
conan::conan_check("github::mrc-ide/conan@v2.0.0", .libPaths())
#> $complete
#> [1] TRUE
#> 
#> $found
#> [1] "conan"
#> 
#> $missing
#> character(0)
#> 

# Missing packages will be returned as the inferred package name
conan::conan_check("github::org/unknownpkg", .libPaths())
#> $complete
#> [1] FALSE
#> 
#> $found
#> character(0)
#> 
#> $missing
#> [1] "github::org/unknownpkg"
