Good Afternoon,
My name is Gabriel, I'm doing an analysis if there is increase or decrease
in dependence on the mutated genes, using 3 or more genes using the fisher exact
test.I performed with success an analysis for two genes using fisher.test( ).
example of the 2x2 contigency table:
Gene A mutated | Gene A normalGene B
mutated| 26 |
12--------------------------------------------------------------------------------------------Gene
B normal | 10 | 50
Now I'm wondering how can I perform the analysis for 3 genes (and construct
the contigency table), as follows: Gene A mutated, Gene A normal, Gene B
mutated, Gene B normal, Gene C mutated and Gene C normal. How do I perform a
fisher test using fisher.test( ) function using this data (3x3 contigency
table)?Can someone help me ?
