IndexOutOfBoundsException when reading XLS file #393
Description
Incanter 1.9.3/Clojure 1.9.0.
I was trying to run first example from Clojure for Data Science which failed with exception (below).
(xls/read-xls (str (io/resource "UK2010.xls")))
where excel file is taken from http://www.complex-systems.meduniwien.ac.at/elections/ElectionData/UK2010.xls
My quick investigation shows that excel is read properly. Exception is caused by clojure.core.matrix.dataset/dataset
Dataset contains nils at some positions. First data row looks like:
(1.0 "Aberavon" "Wales" 2010.0 50838.0 30958.0 "" "" "" "" "" "" "" "" "" 558.0 "" "" "" "" "" 1276.0 "" "" "" "" "" "" "" "" "" "" "" 4411.0 "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" 919.0 nil nil nil nil "" "" "" "" "" "" "" "" "" 16073.0 "" 5034.0 "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" 2198.0 "" ...)
