I dit it with R.

2. should the y variable  take its values like this?

I did like this.

For the moment I did not remove it but I plan to. If one clicks on preview
many previews are generated replacing one another stopping on the last
barplot. Should I remove it, should we leave it as is, or change something?

I have two problems:
1. I get this error.

Error in table(x, y[, i]) : subscript out of bounds

However the results are right. The hours are long right now and I can not
think the reason.

2.There are some more warnings printed.

Should and how can we supress them?

PS: I changed chisq.test as you proposed to chisq.test(xy).
