Testing homogeneity of variances with Bartlett's test


Gives something like this:

Bartlett test of homogeneity of variances data: con by trt Bartlett's K-squared = 12.1292, df = 2, p-value = 0.002324 Bartlett test of homogeneity of variances data: log(con) by trt Bartlett's K-squared = 0.8911, df = 2, p-value = 0.6405
