Dear Rgurus,
Interaction terms in the linear models function lm are specified by the colon :
eg: x ~ a + b + a:b
a shortcut for the above is: x ~ a*b
the output if calling anova on the lm object will be the same in both cases
a .... b .... a:b ... Resdiuals ...
What I am wondering is how the interaction term (a:b) given above should be written in a table in an manuscript?
a ) a*b b ) a$\cdot$ b c ) a:b d) ....
Cheers Eryk.
