OrderBy with changes to decrease and increase sorting

Question

Is there a standard way to sort data.frame across multiple columns, but with changes to decrease or increase? For example, you can order the data.frame file by one variable (decreasing) and the next (increasing).

Is there something like:

mydf[ order(mydf$myvariable,mydf$myvariable2,decreasing=c(FALSE,TRUE)), ] 

Answer 1

 library(plyr) mydf[with(mydf, order(myvariable, desc(myvariable2)), ] # Or, a little less typing: arrange(mydf, myvariable, desc(myvariable2)) 

Answer 2

Quick workaround:

  mydf[ order(mydf$myvariable,-mydf$myvariable2,decreasing=F), ] 

For factors, rows, etc .:

  mydf[ order(mydf$myvariable,-xtfrm(mydf$myvariable2),decreasing=F), ] 

Answer 3

 library(Deducer) sort(mtcars,by = ~ cyl - mpg)
