R tableGrob change format of row

Question

I have some relatively simple code to create a table for printing to a PDF:

library(gridExtra)
df <- head(iris)
tableGrob(df, gp = gpar(fontsize = 8), row         


        

Answer 1

I've just remembered that the formatting parameters get recycled (but only with a sane logic after version >=2.2.0), so you can do,

library(gridExtra)
library(grid)
t1 <- ttheme_default(core=list(
        fg_params=list(fontface=c(rep("plain", 4), "bold.italic")),
        bg_params = list(fill=c(rep(c("grey95", "grey90"),
                                    length.out=4), "#6BAED6"))
        ))

grid.newpage()
grid.table(iris[1:5, 1:3], theme=t1)
