i=1
for(rate in c(2,4) ){
for(shape in c(1,3,5) ){
curve(dgamma(x,rate,shape),xlim=c(0,3),ylab="",col=i,lty=i,add=T)
i=i+1
}
}
How can I add some legend to represent these lines?
i.e. the legend is displayed as
col=1 lty=1 lambda=2 theta=1
col=2 lty=2 lambda=2 theta=3
col=3 lty=3 lambda=2 theta=5
col=4 lty=4 lambda=4 theta=1
col=5 lty=5 lambda=4 theta=3
col=6 lty=6 lambda=4 theta=5
i tried to use
legend( locator(1), expression(lambda=i theta=i),col=i,lty=i)
but did actually get it
can someone help?
Thanks!
