PROC MIXED question: display differences using letters

[xipazpor]

I am using PROC MIXED to examine differeces across 5 different treatments. I would like to know how to enable my 'LSMEANS variable = treatment / ADJUST=TUKEY;' statement to display differences using letters in the output. Any advice is appreciated.

I am using the following code:

%MACRO MIXED1 (DATASET, DEPVAR, ID);

PROC MIXED DATA = &DATASET;

CLASS TRT BLOCK PEN SEX;

MODEL &DEPVAR = TRT/RESIDUAL OUTP=STUDENTRESIDUAL;

RANDOM BLOCK;

LSMEANS TRT/PDIFF=all;

STORE STOREDATA;

RUN;

PROC PLM RESTORE=STOREDATA;

LSMEANS TRT/PDIFF=ALL PLOT=MEANPLOT CL LINES;

RUN;

PROC PRINT DATA = STUDENTRESIDUAL;

WHERE ABS(STUDENTRESID) GT 3.5;

RUN;

PROC UNIVARIATE DATA=STUDENTRESIDUAL NORMAL PLOT;

VAR STUDENTRESID;

RUN;

PROC KDE DATA=STUDENTRESIDUAL;

UNIVAR STUDENTRESID;

RUN;

QUIT;

%MEND;

%MIXED1 (MasterFile, pigWt1, 1);

I'm not sure what you mean by "using letters".

If you mean something like the LINES option in the LSMEANS statement in PROC GLM, as far as I know that is not available in PROC MIXED.

If you mean something else, please explain in a lot more detail.
