Jane, Page 9 of the reference manual, http://cran.r-project.org/web/packages/plotmo/plotmo.pdf, discusses this error.
'The work-around is to simplify or standardize the way the model function is called. Use a formula and a data frame, or at least explicitly name the variables rather than passing a matrix. Use simple variable names (so x1 rather than dat$x1, for example).' 'If the symptoms persist after changing the way the model is called, and the model is not one of those listed in âWhich variables are plottedâ, it is possible that the model class is not supported by plotmo. See âExtending plotmoâ.'
