Read_Plink_FAM(Filename, Is.binary=TRUE, flag1=0)

if TRUE, the phenotype is binary. If phenotype is continuous, it should be FALSE
0 represents the default coding of unaffected/affected (1/2) (default=0), and 1 represents 0/1 coding. flag1=1 is the same as --1 flag in plink. Please see the plink manual.
