Thank you Marc,
I have checked two versions following your suggestions and the default
setting of mar in both versions are same to each other as c(5,4,4,2)+0.1.
Besides, I dont change any default settings about the graphics devices.

States.1252;LC_MONETARY=English_United
States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base



*2.*
