Got it, let's fix that X-axis font size issue in your forestplot! The problem here is that fpTxtGp(cex=0.75) applies a global font size scaling to all text elements unless you explicitly override specific ones—including the X-axis ticks and labels. When you tried making the global cex smaller, it dragged the X-axis font down too, which isn't what you wanted.

Here's how to target different text elements separately: the fpTxtGp() function lets you specify font properties for specific components like xticks (X-axis tick labels) and xlab (X-axis title) independently of the global cex setting.

Modified Code Example #

Replace your existing txt_gp argument with this, which keeps your desired 0.75 size for other elements while locking the X-axis font to its default size (or adjust the cex values to your preference):

forestplot(
  livertabletext, 
  liverdata,
  new_page = TRUE, 
  is.summary=c(TRUE,rep(FALSE,3),TRUE), 
  clip=c(0.1,2.0), 
  xlog=TRUE, 
  graph.pos=3, 
  boxsize=0.1, 
  xticks=c(0.2,0.5,1,2,5,7), 
  txt_gp = fpTxtGp(
    cex=0.75,          # Sets font size for labels, summary rows, etc.
    xticks = fpTxtGp(cex=1),  # Keeps X-axis tick labels at default size
    xlab = fpTxtGp(cex=1)     # Keeps X-axis title at default size
  ), 
  col=fpColors(box="royalblue",line="darkblue", summary="royalblue")
)

How It Works #

• The global cex=0.75 applies to all text elements that don't have an explicit override (like the row labels, summary text, and legend if you have one).
• By adding xticks = fpTxtGp(cex=1) and xlab = fpTxtGp(cex=1), you're telling forestplot to ignore the global scaling for the X-axis components and use the default size (or change 1 to another value like 0.8 if you still want the X-axis smaller, just not as small as the other text).

Bonus: Fine-Tuning Other Elements #

If you want even more control, you can also target specific text groups individually:

• summary = fpTxtGp(cex=0.75): Adjusts only the summary rows' font size
• labels = fpTxtGp(cex=0.75): Adjusts only the left-side row labels
• legend = fpTxtGp(cex=0.75): Adjusts legend text size (if applicable)

This way you can mix and match font sizes exactly how you need them without affecting the X-axis.
