It is currently not possible to use “contr.poly” for incomplete categorical covariates. I will use “contr.treatment” instead. You can specify (globally) which types of contrasts are used by changing “options('contrasts')”. #4
My whole data has over 30,0000 and 884 columns. Now I just sample 1000 rows for testing using using 'survreg_imp' function. Then it has been running for a whole day and never stops, just with 1000 rows data; I also see the warning:

Dear Dr Nicole Erler
My whole data has over 30,0000 and 884 columns. Now I just sample 1000 rows for testing using using 'survreg_imp' function. Then it has been running for a whole day and never stops, just with 1000 rows data; I also see the warning: Warning: It is currently not possible to use “contr.poly” for incomplete categorical covariates. I will use “contr.treatment” instead. You can specify (globally) which types of contrasts are used by changing “options('contrasts')”.
Here shows the codes:
Could you provide some suggestions?
