Your example is not reproducible (see the posting guide), but using
example(hclust)
hc <- hclust(dist(USArrests), "ave")
plot(hc)
plot(hc, cex = 0.3)
the second has much smaller case names.

Hello
I have done a cluster analysis, and I would like to change the font size of my
sample names. I have tried using cex, but this doesn't work/change anything. I
have tried to specify it with cex.main, cex.lab, cex.axis and cex.sub, and can
change all other names in the picture but my sample names.
I can't see what I am doing wrong.
I hope somebody can help me, and I apologize for this probably very simple
question/mistake.
I have around 1000 rows and 50 columns, but have only included a few in my
example.
Thank you in advance!
Kind regards
