Sorry about this basic question. After reading a table, Model=read.table("ModelMat.txt", header=T)
I want to get access to each entry in the table Model. However, if I do > Model[1,1] I get the following, [1] A Levels: A B C My question is, how can I just get the entry "A" without the 2nd line ("Levels: A B C")?
