## Automate a Gauge R&R with many measurement columns

I would like to know if you can take a "spec limit" file that is used to add limits to a capability study and use it to add limits  to the column properties all at once to perform a gauge R&R without inputting them in one by one.  I would like to get a precision to tolerance ratio and need the spec limits for all of the columns.

## Re: Automate a Gauge R&R with many measurement columns

In the code below 'dt' ('dt1') is a reference to the table containing the data (the spec limits). To use the code, do 'File > New > New Script', cut and paste into the window that appears, then do 'Edit > Run Script'.

NamesDefaultToHere(1);

// Make some spec limits to work with

dt1 =

New Table( "Spec Limits",

New Column( "Process",

"Nominal",

Set Values( {"NPN1", "PNP1", "PNP2"} )

## Re: Automate a Gauge R&R with many measurement columns

The populateSpecs no longer works in JMP 13 (unless I'm doing something wrong). I tried to "fix" it, but it doesn't work. I assume that it has to do with evaluating the current values of lsl, usl, and tar in the loop, but I can't figure out how to make it work. Suggestions?

// ******************************************************************************************

// ******************************************************************************************
populateSpecs = Function({dt, dt1}, {Default Local},
// Loop over rows of dt1, and iff there is a matching column in dt set its property
clist = dt << GetColumnNames(Numeric, String);
for (r=1, r<=NRows(dt1), r++,
name = Column(dt1, "Variable")[r];
lsl = Column(dt1, "LSL")[r];
usl = Column(dt1, "USL")[r];
tar = Column(dt1, "Target")[r];
if (Contains(clist, name), Column(dt, name) << Set Property ( "Spec Limits",
{LSL( lsl ), USL( usl ), Target( tar ), Show Limits( 1 )})
)
)
);

## Re: Automate a Gauge R&R with many measurement columns

nevermind, I figured it out on my own:

populateSpecs = Function({dt, dt1}, {Default Local},
// Loop over rows of dt1, and iff there is a matching column in dt set its property
clist = dt << GetColumnNames(Numeric, String);
for (r=1, r<=NRows(dt1), r++,
name = Column(dt1, "Variable")[r];
lsl = Column(dt1, "LSL")[r];
usl = Column(dt1, "USL")[r];
tar = Column(dt1, "Target")[r];
Eval(
Eval Expr(
if (Contains(clist, name), Column(dt, name) << Set Property ( "Spec Limits",
{LSL( Expr(lsl) ), USL( Expr(usl) ), Target( Expr(tar) ), Show Limits( 1 )})
)
)
)
)
);
