Re: [R] the first name of the first column

1. My name is Bert, not Brent; 2. I am not your private consultant -- always cc the list unless you have good reason not to. I have done that here. It looks like this is what you want; if so, you really need to go through an R tutorial or two to learn the basics: d <- structure(list(region =

Re: [R] the first name of the first column

And more helpful, probably, would have been the str() function: > str(mtcars) 'data.frame': 32 obs. of 11 variables: $ mpg : num 21 21 22.8 21.4 18.7 18.1 14.3 24.4 22.8 19.2 ... $ cyl : num 6 6 4 6 8 6 8 4 4 6 ... $ disp: num 160 160 108 258 360 ... $ hp : num 110 110 93 110 175 105
