is there a way to draw generate a figure like this from data in R?

When I said previous thread, I meant this thread:

why does R choose the negative one from multiple available solutions?

here is a matrix A = matrix(c(1,1,2,2,0,0), nrow = 3,byrow = TRUE) this code is to find the svd for it >svd(A) $d [1] 3.162278e+00 1.570092e-16 $u [,1] [,2] [1,] -0.4472136 -0.8944272 [2,] -0.8944272 0.4472136 [3,] 0.0000000 0.0000000 $v [,1] [,2] [1,] -0.7071068 -0.7071068 [2,] -0.7071068 0.7071068 for matrix A, both $u [,1] [,2] [1,] -0.4472136 -0.8944272 [2,] -0.8944272 0.4472136 [3,] 0.0000000 0.0000000 and $u [,1] [,2] [1,] 0.4472136 0.8944272 [2,] 0.8944272 -0.4472136 [3,] 0.0000000 0.0000000 are correct solution. the question is: why does R choose the negative one? for another case, R choose the p…

I mentally read theta_sim as simulated values of theta. It's just a name I used, no significance at all.
