Hi R community,
I am an R beginner and I have a very minor question. Currently, my data have column names starting with V1 and ending with V30. In reality, from V1 to V9 indicate a measure called Efficacy and V10 to V23 with Satisfaction and V24 to V30 with Success. I would like to change the column names but having difficulty doing that. Could you help me find the solution?
