Adding statistic values to the X-Y plot

I was looking for the best way to add statistic values to the plot, and I found a way in this post  "Adding p values and R squared values to a plot using expression() ". It was really helpfull.
Just to check it I add the RSQ and Slope statistics, but the idea is to add more, so lloking to the plot you can have an idea about how the model performs.

Mixing in the Legends dots and lines

Finally I found the info to mix dot and lines in a plot, this way the plot looks nicer:
legend("topright",
        legend =c("Reg Line","Reg Line Bias Corr",

        "Current Value"","Bias adj. value"),
        bty = "n",
        col = c("brown","green4","red","black"),
        lty = c(1,1,0,0),                  

        lwd = c(2,2,0,0),                    
        pch = c(NA, NA, 15,21),           
        pt.bg = c(NA,NA,"red", "yellow"),
        pt.cex =0.5)
