Hello,
In order for us to help we need to know how you've imported your data. What
was the file type? What instructions have you used to import it? Did you use
base R or a package?
Give us a minimal but complete code example that can reproduce your
situation.
Hope this helps,

Absolutely.
It would also help to see what the unique values of each column
*really* are. To that end run and report the results of this:
lapply(your.data.frame, function(x) unique(as.character(x)))
I'll bet you have both "combination" and "combination " as values or
something similar where two different strings look to your eye to be the
same when printed by summary().

Hi,
I have a question regarding data importing into R.
When I import my data into R and review the summary, some of my explanatory
variables are being reported as if instead of being one variable, they are
two with the same name. See below for an example;
Behav person Behav dog Position
**combination : 38 combination : 4** Bank :372
**combination : 7 combination : 4** **Island :119**
fast :123 fast : 15 **Island : 11**
slow :445 slow : 95 Land : 3
stat :111 stat : 14 Water :230
Also, all of the distances I have imported are showing up in the summary
along with a line entitled "other". However, I haven't used any other
distances?
Distance Distance.dog
2-10m :184 <50m : 35
<50m :156 2-10m : 27
10-20m :156 20-30m : 23
20-30m : 91 30-40m : 16
40-50m : 57 10-20m : 13
**(Other): 82 (Other): 18**
I have checked my data sheet over and over again and I think standardised
the data, but the issue keeps arising. I'm assuming I need to clean the
data set but as a nearly complete novice in R I am not certain how to do
this. Any help at all with this would be much appreciated. Thanks so much.
Kind Regards,
Tara Adcock.
