Dear R Wizards:
sorry, I need more help. hopefully, it will help others in the future.
I am using R 2.2.0 Patched (2005-11-07 r36217).
[a]
# copy from the postscriptFont documentation
CMitalic <- postscriptFont("ComputerModern",
c("CM_regular_10.afm", "CM_boldx_10.afm",
"cmti10.afm", "cmbxti10.afm",
"CM_symbol_10.afm"))
postscriptFonts(CMitalic=CMitalic)
# trying this one out. I copied the syntax that worked for lucida
pdf(file="test.pdf", fonts="CMitalic",
version="1.4");
par(family="CMitalic");
plot( c(0,1),c(0,1) );
myeq <- bquote((w[I]==.(1/7)));
text( 0.5, 0.3, myeq );
text( 0.5, 0.7, "this is computer modern");
dev.off();
Now, pdffonts test.pdf (from the xpdf distribution) gives me
$ pdffonts test.pdf
name type emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------

Error (4152): Dictionary key must be a name object
CMSY10 Type 1 no no no 19 0
so, something is still wrong.

I am looking at the docs for postscriptFonts. ?postscriptFonts. May I
suggest that we add two or three more lines to show usage? something
like "plot(c(0,1),c(0,1)); text(0.2, 0.5, "hello", font=2);
dev.off()".
More generally, a documented sample example file that shows usage of
many/multiple postscript fonts and families within one graph would be a
great help.
This is of course all just my own ignorance. In general, I am not yet
sure about the whole font syntax. I wonder what a font="something"
statement in the plot statement itself does. I believe the
"par(family=)" changes the font used for the figure [e.g., axis
labels],
although I am wondering why I am giving a string ["CMItalic"] rather
than a variable [CMItalic]. the ?text documentation does not have an
example of font selection, especially if I want to mix multiple fonts
and from different font families.
[c]
how do I tell a CMD BATCH not to execute the site file? "R
--no-init-file" works only interactively. ( Would it not make sense to
allow this options also for CMD BATCH?) I probably have an incorrect
installation, because the suggestion from "R --help" fails for me
$ R CMD command --help
/usr/local/lib64/R/bin/Rcmd: line 45: exec: command: not found
However, R CMD BATCH my.R works just fine.
Further suggestion: let's have an abbreviation for --no-init-file, too;
e.g., "-I".
[d] regarding my earlier suggestion of a variable that contains the
currently executing file, I know I can put an argv0 <- "filename"
into
each file, but it would be nice if this happened automatically and was
available everywhere. just a suggestion...
please don't see the above as a complaint. R is great, and the effort
you guys put in is terrific. It's just that I am struggling with the
syntax here, and this one is not easy to figure out.
