The problem is that within.data.frame calls as.list.environment with
the default value of all.names = FALSE. I doubt this is a deliberate
feature, and is more likely to be a minor oversight.

Dear Jim,
I’ve tried till today, but I could not solve the problems.
1. despite the scales are the same (equal: lambda ={0.70, 0.75, 0.80, 0.85,
0.90, 0.95, 0.98}), the "matrix" is not equal. If you see, for n = 250 the
column is narrower than for n = 1000, and "lambda" has the same values.

Dear List,
Somewhere I missed something, and now I'm really missing something!

no, I am doing a regression with 6 group data with 2 shared parameters
and 1 different parameter for each group data. the parameter I want to
coerce is for one group. I don't know how to do it. Any suggestion?
Thanks!

To debug this kind of problem you really need to use dput() to provide the data
in your email. [1]

Hi Ravi,
Did you try fixing the problem? What did you try and what went wrong?
The answer is probably
A <- as.data.table(A)
A[ , g15 := cumsum(ifelse(is.na(Time_Diff > 12), 0, Time_Diff > 12))]
A[ , flag_1 := 1:.N, by = c("customer", "g15")]
A[ , g15 := NULL]
but you would have learned more if
