Subject: [R] Select only rows that don't contain one number
Hello!
I have a data frame:
x<-data.frame(a=c(-1,1,2,3,4),b=c(1,-1,3,4,5),c=1:5,d=2:6,e=c(1,2,3,-1,4))
x
How can I grab only those rows that don't contain any -1s (no matter in
what columns? Without writing a loop.
In other words, I want my output to contain only rows 3 and 5 of x.
Thank you very much!
