R2 Frequency Within 77 Indian Populations

I extracted these figures from the link below. This was not a study of haplogroup frequency within specific communities but a general study of the distribution and frequency of haplogroups amongst high caste, low caste and tribal people of India(only some states). The results listed below are by no means indicative of R2 frequency within those communities because the sample sizes are very small in many instances. I just compiled this out of curiosity.
