Brent,
  No, cex doesn't work (as you have discovered).  That is a bug.
I will work on it.

In the meantime, try Rgraphviz called from fa.rgaph or use the output from fa.graph which produces a dot file for processing with any graphic package (including graphviz) which handles the dot language.

However, the display on the screen has very large font size for the coefficients of the relationship between the 11 factors and the 37 items, so the numbers overlap and are therefore illegible.  When I output this to a pdf the problem is exacerbated even further (see attachments).  I tried to use cex=0.8 and cex=0.4 in the pdf argument but it made no difference - what can I do?
