subscript in title of plot

[Wasteva]

  Can someone please help.
 How do you include a subscript in a plot title by passing it to main or opts( in ggplot2)

Thanks.

Hi,

Using the expression argument you can create super- and subscripts

Here I inserted a subscript (inserted between "square brackets") in the title of the x axis:

ggplot(...)+...+labs(x=expression(y[2]))

Cheers

Thanks, would check if it can be passed to main in normal title plot.
Thanks

Hi Wasteeva,

bu that's similar (labs is for axis label and title is for the plot title):

..+opts(title=expression(title[subscript])


or what do you mean?

Try:

x1 <- data.frame(x=1:10,y=(1:10)^2)

ggplot(x1, aes(x,y) ) + labs(x="X values", y = "Y values", title = expression(paste("Some text: ",x^2, "some more text: ",y[3]))) + geom_point()
