Hi R users:
I will like to have a legend with math symbols and also with
the value of a variable.
But I cannot obtain both at the same time (symbol + value of a
variable):
Here is a reproducible example:
m1<-5
m2<-12
I think I am violating a fortune but this "worked":
plot(1:5,1:5,type="n")
legend
("topleft",legend=c(eval(substitute( expression(paste(mu,"=",m1)),
list(m1=m1) )) , eval(substitute( expression(paste(mu,"=",m2)),
list(m2=m2) ) )), lty=1:2)
And efforts at simplification were at least partly successful:
legend("topleft",legend=c(eval(substitute( expression(mu == m1),
list(m1=m1) )) ,
eval(substitute( expression(mu == m2),
list(m2=m2) ) )),
lty=1:2)
plot(1:5,1:5,type="n")
legend
("topleft
",legend
=c(paste(expression(mu),"=",m1),expression(paste(mu,"=",m2))),lty=1:2)
Thank you for your help.
Kenneth
