Creates a matrix based on a "NONMEM style" vector

Creates a matrix based on a vector specifying the lower diagonal elements (as would be defined in NONMEM outputs)

Usage

createNmMatrix(x, dimnames = NULL, byrow = TRUE)

Arguments

x

Vector of values to be placed in the matrix

dimnames

Optional dimension names for output matrix

byrow

(Optional) Should we read in the data into the matrix diagonal by row (default) or by column

Value

A matrix

Details

Places the values in the lower diagonal of an output matrix, and reflects these values across the diagonal. Adds dimension names if provided

  createNmMatrix(1:3)
#>      [,1] [,2]
#> [1,]    1    2
#> [2,]    2    3
  createNmMatrix(1:6)
#>      [,1] [,2] [,3]
#> [1,]    1    2    4
#> [2,]    2    3    5
#> [3,]    4    5    6
  createNmMatrix(1:10, list(LETTERS[1:4], letters[1:4]))
