[R] plotmath: how to use greek symbols in expression(integral(f(tau)*dtau, 0, t))?
I would like to use greek tau as a symbol of variable to integrate
over in plotmath
expression(integral(f(tau)*dtau, 0,t))
but nothing seems to work. I tried d{\tau}, d\tau, etc.,
without any success
Is it possible? How can I accomplish this?
Best regards,
Ryszard

I'd try
...f(tau)~d*tau...

Try
expression(paste(integral(),f(,tau,) d,tau,sep=)))
it works for me.

It does work (albeit without properly including the requested limits
of integrations), but if it is used as a teaching example, it will
obscure the syntax of plotmath expressions. A simple version that gets
the same result is:
expression(integral()*f(tau)*d*tau))
Plotmath expressions are parsed from unquoted text with proper non-
printing separators being ~ for space and * for juxtaposition. The
plotmath paste() is not really the same as the base function paste(),
despite identical names and its main value is as a method for allowing
commas to also be used as separators. Frankly I'm a bit surprised you
got away with adding the undocumented sep= argument. My reading of
the help page for plotmath would have lead me to predict that the text
'sep=' should appear in the output. Instead the sep= is ignored
and the text string is appended to the end of the expression
Try for instance:
plot(1,1, main=expression(paste(a,b,c,d, sep=-) ) )
