[R] Question about parse and expression

[Nitin Jain]

Dear R-users,

In the following example, I would like to see my ylabel as: "beta[3] * x[3] + epsilon" (where beta and epsilon are replaced by their mathematical symbols).

Please advise.

Thanks.

Nitin


i <- 3

ee <- expression(beta[i] * x[i] + epsilon)

xyplot(1:10~ 11:20,
       ylab = parse(text=ee)
       )
