Lattice graphics with combined plot types
The data is of two forms, ie one numeric and another ordinal ie 1.5 and
<.5. The X Value is a factor.
I'm trying to create a lattice conditioned plot with the following
characteristics:
1) The plot is conditioned using the form (Conductivity~Day|Valve)
2) The plot should use a barplot for the ordinal (<.5) and dots for the
numeric (1.5)
3) A line should be created specifying a

Date_Time detected as Duplicated (but they are not!)
I have a problem with duplicated date_time stamps that I do not see as
duplicated.
I read a file with observations taken every 30 minutes:

polypath winding rule with transparency
Hi, I see different results in png() and pdf() for polypath() on Windows
when using the "winding" rule
## overlapping, both clock-wise
x <- cbind(c(.1, .1, .6, .6, NA, .4, .4, .9, .9),
c(.1, .6, .6, .1, NA, .4, .9, .9, .4))

[FORGED] Re: polypath winding rule with transparency
Hi
Just to clarify, I think this IS a problem with grid.path() as well as
polypath().
For the example you give, grid.path() diverts to drawing a polygon
(because there is no 'id' specified), and the NAs in 'x' generate two
separate polygons, which get drawn one on top of the other.
The correct analogy to the polypath() example is ...
x2 <- matrix(x[!is.na(x)], ncol=2)

Do you know if you can map a large minimum spanning tree in R?
Thanks Mike.
My data has longitude and latitude coords and I used distAB {clim.pact}
then mst {ape} to calculate my minimum spanning tree. The nodes are
telecoms sites from all over Australia. My goal is to determine the
minimum cost of linking them via cabling, and I'm starting by
calculating the distance "as the crow flies", but will probably
eventually need to calculate the

readGDAL or raster for reading bit map files
Dear all,
I have asked yesterday of how I can read a simple bitmap file in R cran.
I was suggest to use either readGDAL or raster for loading my bitmap
a. I have done it with readGDAL like
store<-readGDAL(fname='lena256.bmp')
and it works,... but it converts my matrix-like notion of a bitmap to a large vector
b. Raster also returns a class that I can not understand.

Time Delay / Wait
Hi Group,
Is there something like a delay function based on System time or equivalent?
I basically am generating a few graphs and I would like to see each graph
for say 2mins before moving on to the next one?
I can always have an empty for-loop I guess but is there a better way?
Thanks,

REad bitmap files
Dear all,
I am looking for a function that can read a simple bmp file and return me a matrix with their corresponding values.
I have already looked in the packages
require(ReadImages)
require(pixmap)
and also did apropos("image")
but I could not find something that can do something like that.
I have also tried the read.ftable but it also failed.

arguments must have the same length
Hi, anyone up in the night working? Thanks for being there. I'm getting this

Can't seem to straighten it out. Any suggestions? Thanks so much!
PS I saw that someone asked a similar question, but I don't see that

read ESRI file geodatabase feature classes
Hello-
Does anyone know if R can read in ESRI file geodatabase feature
classes, directly from the file geodatabase? I currently have to
export the data out of Arc, to a csv file, then read the csv file. I'd
like to bypass this step and read directly from the file geodatabase.
Thanks for your help.
