[R] corrgram

[Kevin Wright]

Claudia, When you are asking a question about a particular _package_,
you should try to contact the package maintainer with the question.

Now, to answer your question...There is no simple way.  You can always
use the "grid" package to annotate plots however you like.  Here is an
example that shows how it _could_ be done.  Ugly, however.

side.txt <- function (x = 0.5, y = 0.5, txt, cex, font, srt) {
  NULL
}

corrgram(mtcars[2:6], order=TRUE,
         labels=c('Axle
ratio','Weight','Displacement','Cylinders','Horsepower'),
         cex.labels=1.5,
         upper.panel=panel.conf, lower.panel=panel.pie,
         diag.panel=panel.minmax, text.panel=side.txt)

require("grid")
grid.clip()
lab <- "Displacement"

pushViewport(viewport(.04, .5, width = stringWidth(lab), angle=90,
                      height = unit(2, "lines"), name = "pagenum", gp
= gpar(fontsize = 8)))
grid.text(lab, gp=gpar(srt=45), just = c("left", "bottom"))
popViewport()

pushViewport(viewport(.5, .04, width = stringWidth(lab),
                      height = unit(2, "lines"), name = "pagenum", gp
= gpar(fontsize = 8)))
grid.text(lab, gp=gpar(srt=45), just = c("left", "bottom"))
popViewport()
