Hi Joshua, Because there are no values in column ddd less than 1. itemInfo[3,"ddd"]<-0.3645372 itemInfo aaa bbb ccc ddd eee skill 1.396 6.225 0.517 5.775 2.497 predict 1.326 5.230 0.462 5.116 -2.673 waiting 1.117 4.948 NA 0.365 NA complex 1.237 4.170 0.220 4.713 5.642 novelty 1.054 4.005 0.442 4.260 2.076 creative 1.031 3.561 0.362 3.689 2.549 evaluated 0.963 3.013 NA NA NA body 0.748 2.238 0.596 2.019 0.466 control 0.620 2.149 NA NA NA stakes 0.541 1.905 0.227 2.020 2.343 spont 0.496 1.620 NA NA NA chatter 0.460 1.563 0.361 1.382 0.540 present 0.428 1.236 0.215 1.804 2.194 reward 0.402 1.101 0.288 1.208 0.890 feedback 0.283 0.662 NA NA NA goal 0.237 0.474 NA NA NA
digits specifies the number of significant digits ("It is a suggestion only"), so when at least one number is padded with a leading zero it affects the formatting of the other numbers in that column. I suspect that this is an esthetic consideration to line up the decimal points.
