Hi David!
The problem is that the DT is confident, so in my previous example I tried to write a simple dataset that can illustrate what I mean.
Now I have replaced the confident data with other values so it looks more correct:
dput(head(my_data, 10))
gave this output:
structure (list (id = c(1,1,1,2,3,3,4,5,5,5) , dose = c(20,0,20,20,15,20,20,15,20,15), days= structure( c(200,400,100,300,20,300,200,50,50,100), class ="difftime", units ="days")), classe = c("data.table", "data.frame"), row.names = c (NA, -10L), .internal.selfref = <pointer: 0x00000000001f1ef0>)
" ``` " ike this….?
