Usage

data(data.big5)
data(data.big5.qgraph)

Arguments

Format

  • The format of data.big5 is:
    num [1:500, 1:240] 1 0 0 0 0 1 1 2 0 1 ...
    - attr(*, "dimnames")=List of 2
    ..$ : NULL
    ..$ : chr [1:240] "N1" "E2" "O3" "A4" ...

  • The format of data.big5.qgraph is:

    num [1:500, 1:240] 2 3 4 4 5 2 2 1 4 2 ...
    - attr(*, "dimnames")=List of 2
    ..$ : NULL
