The statistic of interest here, R squared added, is the difference between the R squared for both sets of variables (R2Y.AB) and the R squared for only the first set (R2Y.A). If we let kA be the number of variables in the first set and kB be the number in the second set, a formula to test the statistical significance of R squared added by Set B is:

Advanced R . Exercises for Session 1: Effective Coding, Timing. With data on many SNPs, a common task is to compute the ‘r-squared’ between each pair of SNPs. Coding the genotypes for each SNP as 0/1/2 copies of an allele, r-squared for a pair of SNPs can be computed as the square of the Pearson correlation between the genotypes.
