Hello R Users! I have a list called "tabs" that I would like to have the same structure as my list "eqSystem." The two look like they have the same structure but they are different because when I look at their attributes, class(eqSystem[[1]]) is "call" but class(tabs[[1]]) is "formula". I want to have class(tabs[[1]]) as a call too.
So what does "call" mean? And how do I make an object of class "formula" be of class "call"? Thank you so much!!!--Rita > class(tabs) [1] "list" > class(tabs[1]) [1] "list" > class(tabs[[1]]) [1] "formula"> class(eqSystem) [1] "list" > class(eqSystem[1]) [1] "list" > class(eqSystem[[1]]) [1] "call" Rita ===================================== "If you think education is expensive, try ignorance."--Derek Bok -- View this message in context: http://r.789695.n4.nabble.com/What-does-class-call-mean-How-do-I-make-class-formula-into-a-call-tp3623733p3623733.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
