Dear community,
I uploaded an excel with read.xls. My xls file actually have a column which
is an id, ("plot" is the id) :
plot height area
34 7.6 5.4
85 3.2 4.1
89 5.4 8.4
121 6.7 6.2
...
1325 2.1 1.5
However R uses another id, this way:
r id plot height area
1 34 7.6 5.4
2 85 3.2 4.1
3 89 5.4 8.4
4 121 6.7 6.2
...
314 1325 2.1 1.5
I'd like that R used "plot" id because I delete some rows while studying
regression, and R seems to be using the first id 1,2,3,4,...,314. Sometimes
it's a mess to understand what R means in the plots when, for instance,
states that data 200 is influential
Thanks in advance, u...@host.com
