[R] Finding index of specific values in a data.frame

[Kevin Kowitski]

Oh I see, I'm sorry I just plopped it in GitHub for ease of help, I didn't notice I put it under coursera work. This task is not related to coursera, I will separate it out.

I have passed the data from the .csv to a data.frame, have performed the proper matching criteria to generate a data.frame of 0's and 1's, and am outputting the total 1's (therefore matches) found.  I would also like to find the index of these values so that I can output a matrix containing the date and data point which has produced that match. Can anyone help set me in the right direction?
