Question

 > r#quire(car)        # Salaries 데이타을 사용을 위해
    필요한 패키지를 로딩중입니다: car
    Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
      네임스페이스 ‘pbkrtest’ 0.4-2는 로드되었으나 >= 0.4.4가 필요합니다
    In addition: Warning message:

    Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :

    In addition: Warning message:

A car package is the default one it already installed when I install r. I tried to download and include it. But It still got the error that it can not find the Salaries data set that included in car package. What is the problem? Sorry for the Korean message. If you let me know to change message in English, I will retry and reupload the message. Below is my console

UPDATE

I updated this error message in English and tried running the comment's one. But still it is not working.

I think you need to install the package `pbkrtest`. – Gaurav Bansal Aug 29 '16 at 13:56 — Gaurav Bansal, Aug 29 '16 at 13:56

It solved with update r version up to 3.3.2. pbkrtest needs r version to be more than 3.3.2 (newest version). I updated r and reinstall pbkrtest and then car package.

Salaries data set is currently available under [carData package], I solved as the following

install.packages("carData")

data("Salaries", package="carData")
