grpstats for non-numerical data
显示 更早的评论
Hello Reading the grpstats documentation I realized I can easily count the number of elements that meet 2 conditions like this ( From matlab documentation):
My data is not numeric and a similar command results in an error. How can I count the number of elements that has D_S='0-30' & the damage rate is 'No Damage' ? My table is attached below
The first thing that comes to my mind is to substitute the strings with numbers, but I think there is better way! Thank you

Convert those variables to categorical which is what they are, really, not string. Then, internally to Matlab, they are numerical but the interface is still human-readable.)
