[R] problems with levelplot and contourplot

Dear Sundar

Thanks a lot, this resolves the problem of the warning messages.

Yet it does not produce the plot: I only get a blank Quartz panel (i'm 
using R on Mac OS X 1.3).  I attached the file and the corrected code.

Maybe it is a problem of the data?

library(lattice);
mydata <- read.table("avgee.dat");
mymat <- as.matrix(mydata);
mymat <-t(mymat)
vals<-as.vector(mymat);
conc<-c(0.0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5);
a<- c(0.01, 0.025, 0.05, 0.075, 0.1, 0.25, 0.5, 0.75, 1, 2.5,5.0, 
7.5,10, 25, 50, 75, 100);
grid<-expand.grid(x=conc, y=a);
levelplot(vals ~ x * y, grid, region=TRUE, cuts=20,scale = list(y = 
list(log = TRUE)));

-------------- next part --------------


Thanks in advance

Tom
