Using expression() in plot() XXXX

[Dan Abner]

Hello everyone,

I am trying to add the following text (in proper notation) to a
graphic using expression().

X-bar (with a subscript of cv) = XX.

Note: Ideally "cv" would be a subscript, but it doesn't have to be.

 I have the following code:


> text(625,.012,expression(bar(X)cv = 552.01))
Error: unexpected symbol in "text(625,.012,expression(bar(X)cv"

I have also tried the following:

> text(625,.012,paste(as.character(expression(bar(X))),"cv = 552.01",sep=""))
>

While I get no error message for the later, it actually prints

bar(X)

instead of resolving to the proper notation.

Any assistance is appreciated.

Thanks!

Dan

Hi Dan,

If I understood correctly, the following will do:

plot(0, main = expression(bar(X)^{cv}))

HTH,

The code below should have been

plot(0, main = expression(bar(X)[cv]))

Apologies for the noise.
Jorge.-

Hello,

Try

plot(1)
text(1, 1.4, expression(bar(X)[cv] == 552.01))

 [subscript] and  ==

Hope this helps,

Rui Barradas

Any assistance is appreciated.

Thanks!

The following works for me:

     plot(1:10)
     text(4,8,expression(bar(X)[cv]==552.01))
