Hi,
I want to control the plots in the output of the xyplot(). It is
easier to explain it through an example:
#-------------------------------------------------------------
library(lattice);
# months
months <- c("Jan", "Feb", "Mar",
"Apr", "May", "Jun",
"Jul", "Aug", "Sep",
"Oct", "Nov", "Dec");
n <- length(months);
m <- 10;
mdata <- data.frame(x = runif(m*n), y = runif(m*n), z = rep(months,
each = m));
h <- xyplot(y ~ x | z, data = mdata);
plot(h);
#-------------------------------------------------------------
The output of the xyplot() is sorted by the alphabetical order of
months (First Apr, then Aug so on). I need to output such that the
order of the months is maintained, i.e. plot of Jan first, then Feb,
Mar ... so on.
I tried searching on the web and I couldn't find any or probably
didn't understand. I would be much obliged if someone could help.
Thanks
Anand.
