Step 1: Setup and run the R&R as you want to see it run.
Step 2: Click the Show History button (looks like a spiral notepad with a > icon.
Step 3: Copy the stored commands. Looks like 1568646427185.png
Step 4: Create a macro and paste these commands into the macro.

I am trying to use this macro from the minitab library but need the output in xbar.

Gage R&R on multiple measurement columns

I tried the
xbar;
under GageRR;

in the macro but got different results than if I chart it manually.

Manually I get this.

with the macro i get this.

I need the Percent tolerance column as well in my output.

Make sure that you included the Tolerance sub-command.

we work in plastics so we need a little bit of leniency. what is the code for tolerance sub command? is there a list of commands somewhere? I haven't done any coding since the 90's so I am a little bit behind on knowledge here. LOL

this is the main code for my macro. where and what do I add to get the %Tolerance to show?

kkset K1 "Gage R&R Study - Xbar and R Method for "
kkset k5 "Tolerance = "

if lsl = 1 and usl = 1
let tol = high - low
text tol ttol
do i=1:n
let tmp=tol
let tmp2=ttol
kkname k3 x.i
kkcat k1 k3 k4
kkcat k5 tmp2 k6
brief 2
###mtitle k4
###endmtitle
###mtitle k6
GageRR;
XBar;
Parts part;
Opers op;
Response x.i;
Studyvar 6;
Toler tmp;
GToler tmp2.
enddo
elseif usl=0 and lsl=0
do i=1:n
kkname k3 x.i
kkcat k1 k3 k4
brief 2
###mtitle k4
GageRR;
XBar;
Parts part;
Opers op;
Response x.i;
Studyvar 6.
enddo
elseif lsl = 1 and usl = 0
text low ttol
do i=1:n
let tmp=low
let tmp2=ttol
kkname k3 x.i
kkcat k1 k3 k4
kkcat k5 tmp2 k6
brief 2
###mtitle k4
###mtitle k6
GageRR;
XBar;
Parts part;
Opers op;
Response x.i;
Studyvar 6;
lsl tmp;
GToler tmp2.
enddo
elseif lsl = 0 and usl = 1
text high ttol
do i=1:n
let tmp=high
let tmp2=ttol
kkname k3 x.i
kkcat k1 k3 k4
kkcat k5 tmp2 k6

###mtitle k4
###mtitle k6

Response x.i;
Studyvar 6;
usl tmp;
GToler tmp2.
enddo
endif
endmtitle
endmacro

Why do you want the Xbar method? ANOVA is more accurate. Xbar is an approximation that was easier to manually calculate. With Minitab, manual calculation is a non-issue.

Hi Miner, thanks for your great replies for gage r&r analysis macro. I successfully create and modify macro for gage r&r in Minitab with your help.
I would like to ask you where you find all those comands (Gage "name",Xbar;, Gtolerance"tolerance",... and others) for creating macro for gage R&R ?
I ask because I want to create macro for Type 1 gage study using multiple measurement colums in Minitab and I want to use base code of macro Gage R&R on multiple measurement columns.
