For my research I need to create a new subset by removing some columns from the data. I am using the following code:
data_AngNative_raw <- subset(data_AngNative_raw, select = c(-Q1,-EndDate, -Status, -IPAddress, -Progress, -Duration (in seconds), -RecordedDate, -ResponseId))
The problem is that R does not recognise the column Duration (in seconds). I believe, the problem is in the word ''in''. It apparently reads in as a command. What can I do to resolve the issue?
Thank you very much in advance.
