Eliminate title on guild

[Troy S]

I'm trying to eliminate the word drug in the guide for the following plot.  I read the manual but not having much luck.

set.seed(123)
y=data.frame(t=runif(100, 1, 100), fraction=sort(runif(100)),
  drug=sample(letters[1:2], 100, replace=T))
print(ggplot(y, aes(t, fraction, linetype=drug))
+geom_step()
+scale_x_continuous("Days",limits=c(0,168))
+scale_y_continuous("Percent", limits=c(0,1), labels=percent)
+guides(col=guide_legend(title=NULL))
)

last_plot()+scale_linetype("")

To remove word drug use the following code:

theme(legend.title=element_blank())

This will remove the title of the legend. 

 ggplot(y, aes(t, fraction, linetype=drug))+

      geom_step()+

      scale_x_continuous("Days",limits=c(0,168))+

      scale_y_continuous("Percent", limits=c(0,1))+

      theme(legend.title=element_blank())

  

Thanks.
