In R, I run the following commands:
     df = data.frame( x=runif(10), y=runif(10) )
     df2 = df[order(x),]

You use another x from your workspace, you actually want to


  df2 = df[order(df[,"x"]),]

or 
df[order(df$x),] 

And just to prevent yet more confusion, you might also want to avoid 'df' as a name. 'df' is the function that returns the density of the F distribution ...
