Dou you really want to generate a data.frame from that table? BTW: Assigning is done by "<-", not "< -" ... > and later trying to make a comparison of the type t[1,1 ] < 0.1, generates > an error of the type: > > [1] NA > Warning message: > "<" not meaningful for factors in: Ops.factor(t[1, 1], 0.1) Because t[1,1] is an element of a vector of class "factor" (due to the use of data.frame()). BTW: t() is a very basic function in R. Thus it's generally a bad idea to call another object "t", although it works at least in this case. > How can I resolve this? I guess you want something like table(df)[1,1] < 0.1 don't you?
