Hello,

Caveat, I'm pretty new to R.

I'm trying AffyPLM's MAplot by following example from "Quality Assessment of
Affymetrix GeneChip Data" by Bolstad, et al. (
http://www.springerlink.com/content/x88745lrpk331352/?p=5fe6247210644778b597610f5a5c6b43&pi=2)

On page 36 when I made a call to MAplot(data, cex = 0.75). I tried changing
the cex parameter to a small value (0.1), it appeared that not only text are
made smaller, plots were also made smaller without corresponding change in
coordinates. What I mean is a dot on a MA plot is changed in position in
respect to the coordinates. This was not what I was expecting. My intention
is only to change the size of the text "Median", "IQR" as well as the title.

Was this normal?

Timothy
