Dear Jeff,
1) Being a PhD student, I am obliged to pay deep homage to all experts like
you on this forum who provide free knowledge.
2) Since the data is too large and I cannot cut it, I have no other
suitable option to send my full data.
3) This is the same file that I used in the codes mentioned in my
first email. The codes work well while using the data file I sent you till
this code line:
*sp_bk_roll <- spilloverRollingBK12(Data, n.ahead = 100, no.corr = F,
func_est = "VAR", params_est = params_est, window = 260, partition =
bounds)*
**Till now the code works well. After that, when I run the following:*
con = as.matrix(read_excel("DY_Table.xlsx")[,-1])*100
*I face the following error:*
*Error in* *`vectbl_as_col_location()`:*
! Can't negate columns past the end.
ℹ Location 1 doesn't exist.
ℹ There are only 0 columns.
Run `rlang::last_error()` to see where the error occurred.
Now kindly check my issue.
Regards
Chishti
