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!

Regards,
Yan
