Dear all,
I am trying to plot some text in bold face which works fine:
plot(0:1,0:1,type="n")
text(x=0.5, y=0.5, labels=expression(bold("the-actual-string")))
Now when I try to do the following, the displayed text reads thestring:
thestring <- "the-actual-string"
plot(0:1,0:1,type="n")
text(x=0.5, y=0.5, labels=expression(bold(thestring)))
Can someone tell me what I am doing wrong? I assume it is rather simple
but I am stuck somehow.
Thanks in advance,
Roland
P.S. I tried it using ("ancient") R 2.7.0 on Windows32 and version
2.8.1
on GNU/Linux (Ubuntu 8.10).

The better way to do this is thestring <- "the-actual-string" plot(0:1,0:1,type="n") text(x=0.5, y=0.5, labels=thestring, font=2) See ?par (and ?text). There are subtle differences (e.g. how the baslines are aligned), and using plotmath when you do not need it will get you encountering those differences.> Can someone tell me what I am doing wrong?

Using the font argument, I accomplished what I wanted to do. Thanks again, Roland ---------- This mail has been sent through the MPI for Demographic Research.

For a probably more realistic example, see the following: plot(0:1,0:1,type="n") ss1 = paste("there was ",expression(Delta)) ss = substitute(paste("there was ",expression(Delta))) text(x=0.3, y=0.3, labels=ss1) text(x=0.4, y=0.4, labels=ss) Dieter
Here is one way: thestring <- "the-actual-string" plot(0:1,0:1,type="n") text(x=0.5, y=0.5, labels=bquote(bold(.(thestring)))) There is an example in the plotmath help page that shows using bquote (but that page has so much information that I did not find it on my first scan through even knowing what to look for).
