[R] ggplot2: geom_smooth and legend

[Benoit Boulinguiez]

Hi!

simple word thank you Hadley!
an answer bringing a new question... is that possible to mix the colour and
linetype representation with geom_smooth()?

I tried the following code, though it hasn't worked.
I have three different datasets due to non even x-axis (Temp) values I guess
I should handle the matter from this point...no?

CODE
#############
air_N2_desorb_plot<-ggplot() +

	geom_smooth(data=DATA.NC60_N2_v1,
	
aes(Temp,-DrTGA*100,colour="N2_v1"),span=0.05,size=1.6,se=F) +
	geom_smooth(data=DATA.NC60_N2_v2,
	
aes(Temp,-DrTGA*100,colour="N2_v2"),span=0.05,size=1.6,se=F) +
	geom_smooth(data=DATA.NC60_air_v1,
	
aes(Temp,-DrTGA*100,colour="Air_v1"),span=0.05,size=1.6,se=F) +

	geom_smooth(data=DATA.NC60_N2_v1,
	
aes(Temp,-DrTGA*100,linetype="N2_v1"),span=0.05,size=1.6,se=F) +
	geom_smooth(data=DATA.NC60_N2_v2,
	
aes(Temp,-DrTGA*100,linetype="N2_v2"),span=0.05,size=1.6,se=F) +
	geom_smooth(data=DATA.NC60_air_v1,
	
aes(Temp,-DrTGA*100,linetype="Air_v1"),span=0.05,size=1.6,se=F) +
	
	scale_colour_hue(name="Desorption\n Condition") +
	
	labs(x=Temp~(degree*C),y=Weight~Derivative~("%/"*degree*C)) +
	opts(panel.grid.minor = theme_line(colour = "grey94"))

print(air_N2_desorb_plot)


Regards/Cordialement

Hi Benoit,

You could turn the standard errors off with se = F.  Then they'll be removed
from the legend as well.
