For a "write this code for me" question showing no effort, you certainly have a lot of specific demands. This doesn't fit your criteria, but maybe someone will find it useful in base graphics
The plot in the center panel can be just about anything so long as there is one plot per line and kindasorta fits within each. (Actually that's not true, any kind of plot can go in that panel if you want since it's just a normal plotting window). There are three examples in this code: points, box plots, lines.
This is the input data. Just a generic list and indices for "headers" so much better IMO than "directly using a regression object."
## indices of headers
idx <- c(1,5,7,22)
l <- list('Make/model' = rownames(mtcars),
'No. of\ncycles' = mtcars$cyl,
MPG = mtcars$mpg)
l[] <- lapply(seq_along(l), function(x)
ifelse(seq_along(l[[x]]) %in% idx, l[[x]], paste0(' ', l[[x]])))
# List of 3
# $ Make/model : chr [1:32] "Mazda RX4" " Mazda RX4 Wag" " Datsun 710" " Hornet 4 Drive" ...
# $ No. of
# cycles: chr [1:32] "6" " 6" " 4" " 6" ...
# $ MPG : chr [1:32] "21" " 21" " 22.8" " 21.4" ...
I realize this code generates a pdf. I didn't feel like changing it to an image to upload, so I converted it with imagemagick
