I'm trying to get a forest plot on my meta-analysis. I typed

> meta1.for = update(meta1, byvar=EV, studlab=paste(Author, Year))
> forest(meta1.for)

Then I should get a plot according to my textbook but instead, I get

Error in grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y,  : invalid input 'Guti>

It seems the first part is related to font issues but I don't have any information about the last part of 'invalid input 'Guti'. I don't know what's wrong with it.

I also typed

> library(ggplot2)
> library(extrafont)

since somebody suggested it here but it said

Error in library(extrafont) : there is no package called ‘extrafont’

I also tried installing package "forestplot" and then tried again but it had the same error.

    Not sure, but it feels like these are two likely-unrelated errors. For the "there is not package", have you tried `install.packages("extrafont")`? See https://stackoverflow.com/q/66741120/3358272, https://stackoverflow.com/q/47395807/3358272 – r2evans May 11 '23 at 18:42
  • Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. – Community May 18 '23 at 18:54
