This came up on R-sig-geo two days ago and this is what I said:
I have the following code in ggplot2 for turning a SpatialPolygon into
a regular data frame of coordinates. You'll need to load ggplot2, and
then run fortify(yoursp).
fortify.SpatialPolygonsDataFrame <- function(shape, region = NULL

Hi Pascal,
You need the aes_string function:
V1_P2_plot<-function(df, x, y, z) {
ggplot(df, aes_string(x = x, y= y, fill = z)) +
geom_tile()
}
j<-c("k", "l")
i<-"m"
m<-rnorm(25)
vsim<-cbind(expand.grid(k=1:5, l=1:5*10), m)
V1_P2_plot(df=vsim, x=j[1], y=j[2], z=i)

This will be fixed in the next version, but until then you can do

ggplot2 uses the grid package to do all the drawing, and currently
grid doesn't support cross-hatching, so unfortunately the

What are these problems?

Here's a couple of similar plots created with ggplot2. I chose to
turn the data into a data frame with an explicit date column. Using a
log scale somewhat stabilises the variability.
## SAS-L traffic
sas <- structure(list(Jan = c(NA, 546L, 548L, 853L, 1007L, 894L, 514L,
1720L, 1826L, 1941L, 1832
