As in the example, I am trying to substring the Video_full column in a data.frame (video_data_2) I am working on. I want to keep all the characters after the period. The period is always present, there is only one period and it is in a different position in each value for the column.
Date Video_full Instances
1 Apr 1, 2010 installs/AA.intro_video_1 546
2 Apr 1, 2010 installs/ABAC.intro_video_2 548
I got substring to work;
video_data_2$Video_full <- substring(video_data_2$Video_full,11)
And strsplit also;
strsplit("installs/AA.intro_video_1 ",'[.]')
I'm just not able to figure out how to start the substring in a dynamic position or only keep the second value returned by strsplit.
Thanks for any help you can offer for a simple question.
