[R] Data import R: some explanatory variables not showing up correctly in 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.

[R] Data import R: some explanatory variables not showing up correctly in summary

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,

Rui Barradas

[R] Data import R: some explanatory variables not showing up correctly in summary

Hi Tara,

It seems that you categorise and count for each category. Could it be that
the method you use puts everything that doesn't match the predefined
categories in Other?

I'm only guessing because without a minimal  reproducible example it's
difficult to do anything else.

Best wishes
Ulrik

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().

HTH,
