I am a raw novice to R, playing around with a mini .csv dataset created in Excel. I can read it in and the data looks OK in Excel and upon initial inspection in R:
hikes <- read.csv("/Users/eproper/Desktop/hikes.csv", header=TRUE) print(hikes) does exactly what it is supposed to do. Two of the variables are genuine strings, but the others ought to be numeric, and R will calculate their min, max etc. However, is.numeric returns FALSE for all of them; storage.mode returns "language." as.numeric returns "Error: 'pairlist' object cannot be coerced to type 'double'." In what I suspect is a related problem, any command that calls for a variable name requires an initial ~ to work. That is, instead of plot(miles) I have to use plot(~miles). No doubt there is some very elementary mistake I am making, but I can't figure it out. Any help would be appreciated. <http://theturducken.blogspot.com/> [[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.
