match_order_by_labels {dendextend} | R Documentation |
Adjust the order of one dendrogram based on another (using labels)
Description
Takes one dendrogram and adjusts its order leaves valeus based on the order of another dendrogram. The values are matached based on the labels of the two dendrograms.
This allows for faster entanglement running time, since we can be sure that the leaves order is just as using their labels.
Usage
match_order_by_labels(
dend_change,
dend_template,
check_that_labels_match = TRUE
)
Arguments
dend_change |
tree object (dendrogram) |
dend_template |
tree object (dendrogram) |
check_that_labels_match |
logical (TRUE). If to check that the labels in the two dendrogram match. (if they do not, the function aborts) |
Value
Returns dend_change after adjusting its order values to be like dend_template.

Examples
## Not run:
dend <- USArrests[1:4, ] %>%
dist() %>%
hclust() %>%
as.dendrogram()
order.dendrogram(dend) # c(4L, 3L, 1L, 2L)
dend_changed <- dend
order.dendrogram(dend_changed) <- 1:4
order.dendrogram(dend_changed) # c(1:4)
# now let's fix the order of the new object to be as it was:
dend_changed <- match_order_by_labels(dend_changed, dend)
# these two are now the same:
order.dendrogram(dend_changed)
order.dendrogram(dend)
