Thank you Tyler.
I thought the problem was due to the use of expression(...).
Also note that you can simplify your legend text:
c(expression(alpha == 1), expression(alpha == 2))
In general, I find that paste() is overused in plotmath.

Use the text.col argument as below
?legend
x=y=1:100
z=seq(0.5,50,by=0.5)
plot(x,y,type='l',col='black')
lines(x,z,col='red')
legend('topleft',c(expression(paste(alpha," = ", 1)),

Subject: [R] color of math annotation in legend
Dear useRs,
Can someone help me to adjust the color of math annotation in a legend?
The
following code gives me a black "alpha = 2".
x=y=1:100
z=seq(0.5,50,by=0.5)
plot(x,y,type='l',col='black')
lines(x,z,col='red')
legend('topleft',c(expression(paste(alpha," = ", 1)),
expression(paste(alpha," = ", 2))),col=c('black','red'))
Is it possible to make it red? Thanks in advance for your help.
Best,
Zhongyi Yuan
