> Hi everyone,
> the sort function can be used as an alternative to arrange(... ).
> As arguments it accepts x - dataframe, decreasing - TRUE/FALSE, a list of orderings for columns and the list of columns, represented as string names
> for example: 
>  sort(df, TRUE, "col1","col2","col3","col5") # for example, if we want to sort some of the columns in the same order
>  sort(df, decreasing=TRUE, "col1")
>  sort(df, decreasing=c(TRUE,FALSE), "col1","col2")
> Thanks,
> Narine
