Dear R-friends, Could you please help me with a problem?
I have a table with 4 columns: P,Z,S,T. Sometimes z is smaller than s, sometimes z is greater than t. For these smaller/greater z-values, I do need the associated p-value (see example below). I need the whole range of "a" and "b", but I only get the values of "25" for "a" and "5.5" for "b". Also "i" is always "[1]" for all values of p. Could you please help on how to get a matrix form for all separate p-values (for z<s and z>t)? Thanks very much in advance!
