Is there anything odd about it that might be producing the odd

I don't know. Please create a minimal example that isolates the
problem. You can start with

levels(ag.tab$total.density)

ggplot(ag.tab[ag.tab$plant.sp == 'EC',], aes(x = days.out, y =

per.remain)) +

  facet_grid(total.density ~ prop.ec) +

You'll also want to use dput() to send us an exact encoding of your

I don't know. Please create a minimal example that isolates the
problem. You can start with

levels(ag.tab$total.density)

ggplot(ag.tab[ag.tab$plant.sp == 'EC',], aes(x = days.out, y = per.remain)) +

geom_point()

Re: [R] Unable to specify order of a factor

2012-03-21 Thread Justin Montemarano
Ista:

Your attached code did work for me; moreover, the facets were presented in
the desired order with facet_wrap() and facet_grid(), which is what I'm
using because I have a second factor used in facet_grid().

Still, my plots with total.density as a facet are coming out in 16, 32, 8,
and I'm not seeing why.  Below is my plot code -

ggplot(ag.tab[ag.tab$plant.sp == 'EC',], aes(x = days.out, y = per.remain))
> + facet_grid(total.density ~ prop.ec) +
> #add point and error bar data

Is there anything odd about it that might be producing the odd ordering
problem?  FYI, avoiding subsetting ag.tab doesn't do the trick.

Re: [R] Unable to specify order of a factor

2012-03-21 Thread Ista Zahn
Hi Justin,

this gives the correct order (8, 16, 32) on my machine:

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)
total.density <- factor(total.density, levels=c(8, 16, 32), ordered=TRUE)
str(total.density)

order(levels(total.density))

dat <- data.frame(td = total.density, v1 = rnorm(1:length(total.density)))

ggplot(dat, aes(x = v1)) +
  geom_density() +
  facet_wrap(~td)

Does it work for you? If yes, then you need to tell us what you're
doing that is different from this example. If no, please give use the
output of sessionInfo().

best,
Ista

Re: [R] Unable to specify order of a factor

2012-03-21 Thread Sarah Goslee
Ah, you're missing something crucial:

> levels(total.density)
[1] "8"  "16" "32"

is giving you the *labels* of the factor, as *strings*, and what you
get if you use order() on them has nothing to do with the order of the
factor levels, and everything to do with the string sort order for
your locale.

> str(levels(total.density))
 chr [1:3] "8" "16" "32"

The factor levels themselves are in the order you specified.

> str(total.density)
 Ord.factor w/ 3 levels "8"<"16"<"32": 1 1 1 1 1 1 1 1 1 1 ...

Actually I've try that too, Sarah

The test is to run order(levels(total.density)), which I need to be 1 2 3,
not 2 3 1, and your solution still gives me 2 3 1.

I also don't know how to reply to this thread with the previous message

[R] Unable to specify order of a factor

2012-03-21 Thread Justin Montemarano
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.
