Value

a named logical vector

Examples

pkgs <- c("dplyr", "PredictiveEcology/pemisc", "PredictiveEcology/SpaDES.core@development")
isGitHubPkg(pkgs) ## FALSE TRUE TRUE
#>                                     dplyr 
#>                                     FALSE 
#>                  PredictiveEcology/pemisc 
#>                                      TRUE 
#> PredictiveEcology/SpaDES.core@development 
#>                                      TRUE
