[R] Constructing a symmetric matrix with library(corpcor)

I like to compose a symmetric matrix in the pattern as shown below (for 3 x 3 and 4 x 4). For a symmetric matrix of order 5, the result does not seem right. Help? It is possible to write a two-level do loop for the task, but I suppose that is less efficient. > library(corpcor)> r <- 1:3; r[1] 1 2
