`conv()` fails to extract the third column of `pval`

[dillard064]

Seems like conv() uses an older syntax and at the moment:

    pred <- predict(model, classify = Env, ...) # removed `only = Env` argument
    Gmat <- summary(model, vparameters = TRUE)$vparameters[[Env]]
    pvals <- pred$pvals
    names(pvals)[3] <- "blup"

invoks error when I try to use conv():

Error in names(pvals) <- `*vtmp*` :
  'names' attribute [3] must be the same length as the vector [2]
