I wish to use the if command to select a subset for estimation purposes, but also use options for the main command.  This doesn't seem to work, since stata thinks that "if" is a further option.  For example, pca..., comp(6). If I follow this with "if x==1", it won't work because stata thinks that "x==1" is a further option for pca.

Comments please!
