Hello, I hope I am doing this correctly, though I am not sure if a response
will be posted somewhere or if I will get a direct response. I am trying to
import a .txt table in my class on R and for some reason, the header gets
altered and I can no longer read the data. No one in my class had this
problem and the instructors were not sure how to fix it.
Here is the text table:
Kind Fatness Wt
Ewe 4 10.3
Ewe 8 11.9
Ewe 11 15
Ewe 15 17.1
Ewe 15 18.7
Ram 5 12.4
Ram 4 14.3
Ram 10 16.6
Ram 8 18.8
Ram 14 21.9
Here is the code that I copied from the instructors handout (simple cut and
paste, no alterations):
Lambs = read.table("Lambs.txt", header = TRUE)
> Lambs
??..Kind Fatness Wt
1 Ewe 4 10.3
2 Ewe 8 11.9
3 Ewe 11 15.0
4 Ewe 15 17.1
5 Ewe 15 18.7
6 Ram 5 12.4
7 Ram 4 14.3
8 Ram 10 16.6
9 Ram 8 18.8
10 Ram 14 21.9
> par(mfrow = c(1, 2))
> plot(Fatness ~ Kind, data = Lambs)
Error in eval(expr, envir, enclos) : object 'Kind' not found
I think it is because the "Kind" header got altered into "
??..Kind" and it
can no longer identify the object.
Can anyone help?
Thanks
It's hard to diagnose the problem with importing the file without
the file itself, but you can easily change the column names:
colnames(Lambs) <- c("Kind", "Fatness", "Wt")
You should also open the text file itself and check that everything
looks okay with the first few rows.

Responses will be sent to the list and bounced to you if you are subscribed: most replies also cc the thread and OP (and I think the server notes this so you don't get two copies). It looks like it may be an encoding problem in the .txt file. If your data allows it, try opening it up with a text editor and saving it again as something like Latin-1. Everything looks ok on the R end of things. Michael On Wed, Jan 18, 2012 at 4:39 PM, Berneet Kaur <berneet.kaur at ucdmc.ucdavis.edu> wrote:> > > ?
