Hi All, I have some data from which I set four points to be breaks. Based on these points, I cut the dataset into four groups and assign a number to it:
<=331.04 assign 0 >331.04 <=476.07 assign data-331.04/(476.07-331.04) >476.07<=608.66 assign 1 >608.66 <=791.5 assign 791.5- data/(791.5-608.66) > 791.5 and NA assign 0 Breaks 331.04 476.07 608.66 791.5 NA m_group 0 x 1 x 0 0 I can use cut() to group the data according to the breaks but having difficulty to assign the two calculated interval values. Thank you very much!
