Dear R-List,
I have nested data with cases grouped by IDs and I want to remove all cases
with specific IDs.
something like
df<-data.frame(id=c(1,1,1,2,2,2,3,3,3,4,4,4,5,5,5),var=c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15))
subset(df,id== 1 | id == 3)
Having a very large dataset with many IDs to remove this solution leaves me to
write quite a long list of "id == x | id == y | id == z ...". I wonder if there
is a more elegant way to do this? I tried with "id = c(x,y,z)" but this did not
give the proper result.
Any suggestions? Thank you!
Best wishes
Alain
