TSA - STATA-R directories

[Carlo Caponio]

I'm trying to run a Trial Sequential analysis as reported by https://journals.sagepub.com/doi/pdf...867X1301300106
Everything is installed and when I input the following command I get this error.
Command : metacumbounds ln_hr se_ln_hr N, data(loghr) effect(r) id(study) surv(0.40) loss(0.00) alpha(0.05) beta(0.20) is(APIS) graph spending(1) rrr(.15) kprsrce(StataRsource.R) rdir(C:\Program Files\R\R-4.2.1\bin) shwRRR pos(10) xtitle(Information size)

ERROR: R executable Rterm.exe not found in C:\Program Files\R\R-4.2.1\bin, cannot access R software
yee
file bounds.dta not found

I found Rterm.exe and its directory is ok, I guess
Any help how to overcome this issue?
Thanks in advance for any advice
Carlo

Has anyone solved it? I also encounter this problem.

I think I can your first question, you need to enter 'C:\Program Files\R\R-4.2.1\bin\' instead of 'C:\Program Files\R\R-4.2.1\bin' , that lacks a '\' . Unfortunately, I'm on the way finding the way how to solve the second question, It cannnot be found in any of my search engine. But I guess that 'bounds.dta' has some connections with 'metacumbounds '. Wish me good luck!

[Muhua Shi]

will, now I try to change some part of the code instead of use the menu.
'metacumbounds a b c d, data(count) effect(f) id(study) alpha(0.05) beta(0.20) is(AIS) stat(rr) graph spending(1) rrr(.15) listRin keepR kprsrce(StataR_source.R) rdir(D:\R\R-4.2.0\bin\x64\) listRout shwRRR pos(12) xtitle(Information size)'
see?there's something different from yours.
and I get some process in the whole program.
but my English is poor, so maybe you can find the answer in these statements?
I need to emphasize that, in these statements,'bounds.dta'''exist! so we are closer to the truth!
