Hi all:

I'm attempting to create a faceted plot with ggplot2 and I'm having issues
with a factor's order that is used to define the facet_grid().

The factor (named total.density) has three levels - 8, 16, and 32 - and I
would like them presented in that order.  Running
order(levels(total.density)) yields the incorrect order of the facet grid -
2 3 1, corresponding with 16, 32, and 8.

I have attempted correcting the order with the following solutions (of
course, not run at once):

#total.density <- relevel(total.density, '8')
        #total.density <- as.numeric(levels(total.density)[total.density])
        #total.density <- factor(total.density, levels = c('8','16','32'))
        #total.density <- factor(total.density, levels =
levels(total.density)[c(3,1,2)])
        #library(gregmisc)
        #total.density <- reorder.factor(total.density, c('8', '16', '32'),
order = T)

The data are as follows:

total.density <-
c(8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,16,16,16,16,16,16,16,16,16,16,16,16,16,16,16,16,16,16,16,16,16,16,16,16,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32)

I'm running R 2.14.2 with all packages up-to-date as of 21.3.2012.

Any help would be greatly appreciated.
