[R] create one bigger matrix with one smaller matrix

Dear R users, Suppose that I have a matrix A A <- matrix(c(1,2,3,4),2,2) > A [,1] [,2] [1,]13 [2,]24 With this matrix A, I'd like to create bigger one, for example, [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11] [,12] [,13] [,14] [1,]1313

[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,

r 'q's (1,2,3,4) and the forth 'p' element (4) has two 'q's (1,2); 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
