Is there a cleaner way of combining two expressions.
This example works and gives what I want
plot(1:10)
aa <- expression(alpha==.05)
bb <- expression(beta ==.80)
aabb <- expression(alpha==.05 ~ ", " ~ beta ==.80)
text(5, 10, aa)
text(5, 9, bb)
text(5, 8, aabb)
text(5,1, parse(text=paste(deparse(aa[[1]]), deparse(bb[[1]]), sep="~")))
text(5,2, parse(text=paste(deparse(aa[[1]]), deparse(bb[[1]]), sep="~',
'~")))
Is there a cleaner way of combining the expressions aa and bb to get the
effect of the last two lines?
