IQR unbound

When quickloading plot I kept running into the following issue:

The variable BATCH-STATISTICS::IQR is unbound.
   [Condition of type UNBOUND-VARIABLE]

Ignoring it works fine (at least for me) but is this supposed to happen?
Also, I was able to make it go away by commenting out the following lines at the bottom of statistics/src/batch:

+;; (defalias iqr interquartile-range)
+;; (export 'iqr)

I'm not sure if this is really an issue, but I spent a full day trying to figure it out so I thought I would at least leave my solution here if nothing else. If this is not an issue, feel free to correct me. Thanks!

plot で quickload の失敗を再現し、statistics/src/batch を調査してください。特に、報告で言及されている defalias 行と export 行を確認してください。BATCH-STATISTICS::IQR が未束縛である理由を確認し、IQR の機能を引き続き利用できる状態で、警告なしに quickload が完了することを検証してください。
