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,

Hello, Try plot(1) text(1, 1.4, expression(bar(X)[cv] == 552.01)) [subscript] and = Hope this helps, Rui Barradas Dan Abner wrote> > 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 > > ______________________________________________ > R-help@ mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >-- View this message in context: http://r.789695.n4.nabble.com/Using-expression-in-plot-XXXX-tp4615861p4615925.html Sent from the R help mailing list archive at Nabble.com.
The following works for me:
plot(1:10)
text(4,8,expression(bar(X)[cv]==552.01))
