[R] how to draw a legend outside of the plot

Dear R users, I have three plots, so I tried, for exmple, par(mfrow=c(2,2)) y1 - rnorm(100) y2 - rnorm(100) y3- rnorm(100) plot(y1);plot(y2);plot(y3) Here, I'd like to put a legend on the bottom right hand side (empty space). is it possible? Thanks for helping, Kathryn Lord

[R] create new matrices with specific patterns

); in other words, Is there the easyiest way to create B,...,E in R? Actually, the example above is a toy example and the matrix A I have is around 10,000 by 10,000 and the pattern is also very complicated. Any suggestion will be greatly appreciated. Best, Kathryn Lord [[alternative HTML
