Remove records from a large dataframe
Hi, I am trying to remove a series of records from a large dataframe. The
script I have written works fine but takes a long time to run. Can anyone
suggest a quicker way to do this?
Here is an example of the code I've written. The end result of this bit of
code would be a dataframe with any records relating to ID 1 or ID 4 removed:
#dataframe
id <- c(1,1,1,1,2,2,2,2,2, 3,3,3, 4,4)
