Jackknife estimates of predict.lda success rate
...is.
Any suggestions of how to generate the jackknife reclassification to
assess classification accuracy? (BTW, commands I used to generate
predictions appended below.)
Many thanks

Plots from lda and predict.lda
...discriminant in the

what is happening here? (I can attach files with plots separately if
requested).
