[R] Problem with legend

[Komine]

HI,
This code is part of a code I used to do a linear regression:

>points(var1~var2,data=Regress,pch=21,bg="grey")
>reg11<-lm(var1~var2,data=Regress)
>abline(lm(var1~var2,data=Regress),lty=2,lwd=2,col="grey")
>legend("topleft",legend=
>c("NDII from composite",  
>"y= 0.0007x - 0.1156",expression(paste(r^2 == 0.88)),"p-value <0.001"),
>pch=21,
>bty="n")

But I have a problem to complete the legend.
Indeed, on the legend, I want to display a point  in front "Ndii from
composite images." But when I run my code I get a point in front, "Ndii from
composite images" but also before "y = 0.0007x - 0.1156", "r ^ 2 == 0.88," "
and " p-value <0.001 "."
How can I do to obtain only one point in front "Ndii from composite images"?
Thank you in advance
