I cannot find in the literature a way to conduct the following t.test on 2 objects, A and B

A                                       B
col1 col2 col3                  col1 col2  col3

Where col(i)'s name is identical in both A and B (they are names of tissues).

How do I test (t.test) if each tissue across the object is signifanctly different?? (i'm pretty sure I have to use tapply())

Also is there a way to multi plot all 89 tissues showing the A values and the B values..

thank you
