如果你把model statement里的/solution 去掉，默认的输出里就有R2

或者把solution后面加上ss3 （也可能是ss1或者ss2，记不清了，sorry）你可以试一下

proc statement后加outstat=吧？去查查吧！

OUTSTAT=SAS-data-set
names an output data set that contains sums of squares, degrees of freedom, F statistics, and probability levels for each effect in the model, as well as for each CONTRAST that uses the overall residual or error mean square (MSE) as the denominator in constructing the F statistic. If you use the CANONICAL option in the MANOVA statement and do not use an M= specification in the MANOVA statement, the data set also contains results of the canonical analysis.
这个是我查到的，没看到有R2。不过有数据的话，运行一下就知道了。
