Chi square test to investigate further

#1
I want to analyse the change over time for 2 groups (over 35 years), each group in each year has been recorded for 6 categories.
I want to see if there is a difference in the frequency recorded in each of these categories over time for each newspaper, and to compare between newspapers.

The categories A, B, C etc. are not ordinal but on a scale, but A, B, C etc do refer to certain key words used to refer to animals, which I have tallied up and changed into (100%) percent frequencies for each year in each newspaper type.

So I am basically interested to know if newspapers have changed their attitude (the terms act as a proxy) to animals.

For example this is how the data looks like

Liberal newspaper Conservative newspaper
% A | % B | %C | %D | % E | %F % A | % B | %C | %D | % E | %F
1994 1 15 25 28 20 11 3 12 26 27 18 13
1995 10 15 26 37 13 8 8 11 24 20 33 4
1996 4 11 24 20 33 8 8 15 26 37 13 10


Can anyone help me to understand what statistical test I should run in r?
