`Agem`

`Wrinkl`

These data are intended to show the utility of `dmm()`

for analysis of a multi-trait dataset with all the real world complications. The dataframe has identifiers which are NA or duplicate or alphanumeric, some base animals are missing, some traits and factors have missing values, and the eleven traits need to be in a matrix for multivariate analysis.

These data were collected over the period 1950 to 1970 by CSIRO under the direction of Dr Helen Newton Turner. The dataset was recovered from the author's research files, and are used with permission from CSIRO.

These data form part of the set which were used to estimate genetic parameters in the publication: Brown,G.H. and Turner,Helen Newton(1968)Aust.J.Agric.Res.19:303-22
