Why are you calling anova.glm on an object of class c("aovlist",
"listof")? Also, why give the data = kk argument to anova.glm (which does
not have such an argument)?
I have no idea what you intended, but there is no anova method for
a multistratum aov fit. I suggest you look at the print and summary

All text files are strings. It is a column of integer numbers, and so is
converted to an integer variable in R.
If you wanted something different, read ?read.table and set colClasses.
