Change line width in ezPlot?

[or duek]

Hi,
Is there a way to change line width and/or color in ezPlot?

[pulpo]

you can change the color with

scale_colour_manual()

for example: 

ezPlot(...)+

scale_colour_manual(values=c("#FF0000","#0000FF"))

Thank you very much.

This is very helpful. 

I understand there is no way to change line width... :(

Is there an option to set those color criteria as default?
