Hi all,
I would like to
1. Read in an arcmap image into R (I can export pretty much any type of image
jpeg, bitmap etc from arcmap)
2. Use R to create a nice colour legend in the plot
First of all, Is this possible?
So far I'm stuck on point 1. I have tried read.pnm() from pixmap and
read.jpeg() from rgl.
the pnm example provided works fine
x <- read.pnm(system.file("pictures/logo.ppm", package="pixmap")[1])
plot(x)
#draws an R logo, nice :-)
But my code returns an error
x<-read.pnm("C:/Documents and Settings/simonp/My Documents/Simon BTO/RELU/GIS
data/ten km areas in analysis.bmp")
Error in pm.readmagicnumber(con) : Not a PNM format file
I have tried changing the dpi when I export the image but still no cigar.
I have dredged the help forum for related files and read the help files. My Os
is windows XP and i'm running 2.8.1.
I feel I'm missing something obvious!
Thanks
