是否有一种优雅的方法来使ggplot2中的整个图具有统一的字体大小

Question

I read online that the size of the fonts in a plot plotted with ggplot2 is relative to the base_size specified in the theme() .

I also found that the size of the specific elements can be modified by doing something like:

theme(axis.title.y = element_text(size = rel(1.5) )

I am using the theme_bw() and would like all of the text in my plot: the labels of the axis, the title of the legend, the items in the legend, the breaks in the axis, to have the same font size. How can this be done?

EDIT:

I (almost) achieve what I want by using the theme_tufte() as suggester by @lawyeR.

g + theme_tufte() + theme(axis.rect=element_line() )

gives me a plot with x and y axis drawn as lines. However I would like to have the plot where x and y axis form a box.

How can I draw a box for the x and y axis?

I solved my problem creating a theme of my own, which combines theme_bw() as its basic theme + the suggestion form @lukeA, + some custom stuff which I need.

theme_my <- function(base_size = 14, base_family = "Palatino")
{
  txt <- element_text(size = 14, colour = "black", face = "plain")
  bold_txt <- element_text(size = 14, colour = "black", face = "bold")

  theme_bw(base_size = base_size, base_family = base_family) +
  theme(
    legend.key = element_blank(), 
    strip.background = element_blank(), 

    text = txt, 
    plot.title = txt, 

    axis.title = txt, 
    axis.text = txt, 

    legend.title = bold_txt, 
    legend.text = txt ) 
}
