I'm using the package 'gdata' and 'drop.levels' in the following code as a simplified example of what I want to do, pinpointing the issue of isolating variable in a data frame:
/dfNamesAndHeight <- data.frame("Name" = c('Bill','Bob','Bo'), "Height" = c(73,68,83)) name_Bob <- drop.levels(dfNamesAndHeight[2,1]) cat(name_Bob, " is a good guy.") / The output is "> 1 is a good guy". Print instead of cat returns ">Error in print.default(xx, quote = quote, ...) : invalid 'quote' argument". When you just enter 'name_Bob' the output is: " >[1] Bob Levels: Bob" Is there any way to isolate 'Bob' without the 'Levels: Bob'? -- View this message in context: http://r.789695.n4.nabble.com/Drop-ALL-Levels-of-a-Data-Frame-Object-tp3903788p3903788.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.
