Hi List, I'm trying to built a list where there are some missing data in some columns, then I would like to know what I should put in these blank spaces when building the vector. eg:
color<- c("red",?,"orange","green",?,?,?) size<- c(2,1,?,3,?,?,8) Thanks, Natalia [[alternative HTML version deleted]] ______________________________________________ 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.
