Apologies in advance for the simplicity of this question. I am trying to import a .dat file from a website into R with the following code:
www = "http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat"
data <- read.delim(www, header = TRUE, sep="\t")
I want to access the Value portion of the data.frame, however, I am unsure about the dimensions of the data.frame, if I type ncol(data) it returns 1 which I was expecting three. How do I access the "third" column of this data.frame?
