Hello, I would appreciate if someone could help me resolve the following:
1. df1[!is.na( X1 | X2 | X3 | X4 | X5),][,1:5] # This does not work 2. Is these message harmful? The following object(s) are masked from 'df1 (position 3)': X1, X2, X3, X4, X5 Thanks, Pradip Muhuri #Reproducible Example set.seed(5) df1<-data.frame(matrix(sample(c(1:10,NA),100,replace=TRUE),ncol=5)) attach (df1) #delete rows if any of them NA for X1 df1[!is.na( X1),][,1:5] # This works #delete rows if any of them NA for X1, X2, X3, X4 or X5 df1[!is.na( X1 | X2 | X3 | X4 | X5),][,1:5] # This does not work ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
