Apologies for being vague,
The structure of the output is as follows:
Still no code?
$ cluster1 : Named num [1:131] 3.05 2.71 3.26 2.91 2.88 3.11 3.21
-1 2.97
3.39 ...
..- attr(*, "names")= chr [1:131] "6667" "6668" "6669" "6670" ...
With 613 clusters. What I require is abstracting the first and
last value
of
- attr(*, "names")= chr [1:131] "6667" "6668" "6669" "6670"
Those values are in an attribute:
Corrections:
? attribute
?attributes
? attr
Your specific request may (perhaps) be addressed by something like:
attrnames <- attr(objname["cluster1"], "names")
^ ^ should be doubled square-
brackets
attrnames[c(1, length(attrnames)]
^ missing right-paren
Might work:
attrnames <- attr(clusobj[["cluster1"]], "names")
attrnames[c(1, length(attrnames))]
