I produced a cluster with hcluster. original dendogram.

For formatting purposes I used as.dendogram. When I did that my labels were cut of. vertical dendogram

Even more by the horizontal orientation. The one I need. horizontal dendogram

The problem does not seams to be in margins since (for the horizontal one) I used par(oma = c(0, 0, 0, 8) with not label effect. It only a reduced my margins but not give more room for labels names. How can I make sure that the plot shows the entire model names?

You should probably change mar and not oma in par():

mm <- matrix(rnorm(20), ncol = 4)
colnames(mm) <- c("leaf1", "leaf2", "leaf3", "very_long_leaf_realy")

# compare:
plot(as.dendrogram(hclust(dist(t(mm)))), horiz = TRUE)

# with:
oldpar <- par(mar = c(5, 4 ,4 , 8))
plot(as.dendrogram(hclust(dist(t(mm)))), horiz = TRUE)
par(oldpar) # restoring ploting parameters
