[R] Anova() in car not works after loading piecewiseSEM package

[Jinsong Zhao]

Hi there,

In the code below, you may notice that the Anova() function from the 
*car*package does not behave as expected after loading the 
piecewiseSEMpackage. I haven't been able to identify the cause of this 
issue or find a working solution. Any suggestions or insights would be 
greatly appreciated.

Best,

Jinsong

   This is piecewiseSEM version 2.3.0.2.
