hello,
i need to annotate a plot with an expression and a variable value -
like:
plot(1:4)
dat<-1:2
text(2:3,2:3,expression(paste(bar(x)==dat)))
... but with the dat values plotted, 1 at x=2,y=2, and 2 at x=3,y=3.
One way ... actually the first success after several earlier failed
efforts that I thought should have worked :
plot(1:4)
dat<-1:2
text(2:3,2:3,labels=sapply(dat,
function(x) as.expression(substitute(list(bar("x") == x),
list(x=x) )) ))
