R help - Nov 2009 - EBImage do not read an Image: requested image not found or could not be loaded

Hello all,

I am trying to use the EBImage package,
(EBImage 3.2.0 and ImageMagick 6.5.7-9 2009-11-19 Q8 (dinamic linked) 
with R 2.10.0 winXP)
but I get the following error:

#---------------------------------------------
 > library(EBImage)
Loading required package: abind
 > ?readImage
 >  ## Reads and display images
 >         f = system.file("images", "lena-color.png",
package="EBImage")
 > f
[1] "C:/R/library/EBImage/images/lena-color.png"
 >
 >  x = readImage(f)
Warning message:
In readImage(f) : requested image not found or could not be loaded
 > x
NULL


Is there a way of to solve the problem? Or make a workaround? (but with 
no source code compilation)

Thanks for any reply!

Works for me with the same setup.
Are yiu sure the file exists on your machine and is uncorrupted. Do you 
have access and read permissions?
