how to recode in my dataset?
...irst, i'd like to say
something about the idea of recoding:
My dataset have three variables:type,soiltem and airtem,which means
grass type, soil temperature and air temperature. As we all known, the
change of air temperature is greater than soil temperature,so the
values in those two different temperaturemay represent different
range.
My recoding is to recode soiltem with 0.2 intervals, and airtem with
0.5 intervals, that is:
In soiltem:0~0.2<-0.1, 0.2~0.4<-0.3, 0.4`0.6<-0.5,...etc;
In airtem:0~0.5<-0.25, 0.5~1<-0.75, 1`1.5<-1.25,...etc;
My example like this:
type<-c(1, 1, 2, 3,...
