I am using vegan package for estimating dissimilarity within and between
clusters, and plotting them. The following code gives me a dendrogram
without X-axis. How would I add X axis to the plot? Below "dataEnv" is a
matrix of my environmental variables. dataFact$Source_by_Type has the
levels that delineate clusters.

dataEnvDist <- vegdist(dataEnv, method="bray") ## bray curtis dissimilarity
meanDist <- meandist(dataEnvDist, dataFact$Source_by_Type)
plot(meanDist, ylab="Mean dissimilarity")

Thanks in advance.
