Hi ! I am a new user and quite confused by R-indexing.
Make a list and get the attributes lst <- list(x = 1:3, y = 4:6, z = 7:9) attributes(lst) This returns: $names [1] "x" "y" "z" I can easily do: nm <-names(lst) or nm <-attr(lst,"names") which both return the assigned names of the named list 'lst', but why then this doesn't work: lst$names ? I am confused ... Moreover, I noticed that some of the objects (e.g. plot objects returned by ggplot) also have attributes when queried by the 'attributes' function, but they are accessible by the $ notation. (e.g. xydf <- data.frame(x = 1:5, y = 11:15) plt <- ggplot(data = xydf, aes(x = x,y = y)) + geom_point() attributes(plt) Now we can change the title: plt$title <- "My Title" plt So is it some inconsistency or am I missing something important? ______________________________________________ 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.
