Suppose I've specified that the xlab for a plot is
expression(bold(species~(italic(N1))))
In other words, I want the axis label to be bold, italic 'species (N1)'
Now, I want the title for the plot to be have this label embedded in the
title.
Say, 'This is the plot for Species (N1)'.
For a variety of reasons, I've set this up so that the xlab is a global
parameter (basically, because the labels are set in a function which
when called, generates various plots):
x_label <<- expression(bold(species~(italic(N1))))
So, in the title, I've tried
title(main=paste("This is the plot for ",x_label,"nullcline", sep=" "));
but what this does is generate something like
'This is the plot for bold(species~(italic(N1)))'
In other words, it pastes the text of the expression into the title, but
not what the expression 'evaluates' to.
Is there any way around this?
You instead need the `bquote` function. The `paste` function will only confuse things. In this
particular instance it is embedding the literal as.character result of 'x_label'-value in a
character object rather than in an expression-object. Since you have not offered a full example it
remains unclear whether you want the words: "species" or "N1" rather than the
values of those names.
Thanks. I had wondered if bquote was the solution, but wasn't sure. Have
followed your suggestion, but for the moment, am having problems getting
it to work. I haven't figured out how to get bquote to actually evaulate
the expression.
Thanks in advance...
