Add labels in dendogram in R - r

Question

I am trying to apply Hierarchical Clustering for Time Series in order to identify the states with similar behaviors in the time series for residential_percent_change_from_baseline. I get the dendrogram but the index i get in the x axis are just numbers and I want the states names.
my data looks like this:
Data
And this is some part of my code
data <- dataset
#Convert to factor
cols <- c("country_region_code", "country_region", "sub_region_1", "iso_3166_2_code")
data[cols] <- lapply(data[cols], factor)
sapply(data, class)
data$date <- as.Date(data$date)
summary(data)
#Data preparation
n <- 10
s <- sample(1:100, n)
i <- c(s,0+s, 279+s, 556+s, 833+s, 1110+s, 1387+s, 1664+s, 1941+s, 2218+s, 2495+s, 2772+s, 3049+s, 3326+s, 3603+s, 3880+s, 4157+s, 4434+s, 4711+s, 4988+s, 5265+s, 5542+s, 5819+s, 6096+s, 6373+s, 6650+s, 6927+s, 7204+s, 7481+s, 7758+s, 8035+s, 8312+s, 8589+s, 8866+s)
d <- data[i,3:4]
d$residential <- data[i,11]
d[,2] =NULL
str(d)
pattern <- c(rep('Mexico', n),
rep('Aguascalientes', n),
rep('Baja California',n),
rep('Baja California Sur',n),
rep('Campeche',n),
rep('Coahuila',n),
rep('Colima',n),
rep('Chiapas',n),
rep('Chihuahua',n),
rep('Durango',n),
rep('Guanajuato',n),
rep('Guerrero',n),
rep('Hidalgo',n),
rep('Jalisco',n),
rep('México City',n),
rep('Michoacan',n),
rep('Morelos',n),
rep('Nayarit',n),
rep('Nuevo León',n),
rep('Oaxaca',n),
rep('Puebla',n),
rep('Querétaro',n),
rep('Quintana Roo',n),
rep('San Luis Potosí',n),
rep('Sinaloa',n),
rep('Sonora',n),
rep('Tabasco',n),
rep('Tamaulipas',n),
rep('Tlaxcala',n),
rep('Veracruz',n),
rep('Yucatán',n),
rep('Zacatecas.',n))
d <- data.matrix(d)
distance <- dist(d, method = 'euclidean')
hc <- hclust(distance, method="ward.D")
plot(hc, cex=.7, hang = -1, col='blue', labels=pattern)
I get this dendrogram when I don't specify labels
dendrogram with numeric labels
But when I do I get this error
Error in graphics:::plotHclust(n1, merge, height, order(x$order), hang, : invalid dendrogram input
I hope somebody can help me, I am little bit tired of this

Answer 1

Maybe it will work with an alternative to the base r plot function. Try ggdendroplot. It should display the labels on the axis. You will need ggplot2 for this.
devtools::install("nicolash2/ggdendroplot")
library(ggdendroplot)
library(ggplot2)
ggplot() + geom_dendro(hc)
If you want to modify it (turn it, color it, etc.) check out the github page: https://github.com/NicolasH2/ggdendroplot
