You want the whole thing to be an expression. To insert values, bquote()
is your friend. Something like this

legend(bty="n", "topright",
   bquote(r^2 == .(round(summary(lat_x)$r.squared,digits=3)
          * "," *
          P == .(round(coefficients(summary(lat_x))[2,4], digits=3)
          )
)

(untested, if you want us to test, give us a reproducible example...)
