[R] ImageMagick not seen by movie3d function from rgl package

[eugen pircalabelu]

Hello R-users,
I have downloaded and installed a binary version for Windows OS of ImageMagick (ImageMagick6.5.6-10-q16-windows-dll.exe), I have installed the rgl package and i've tried  running the following example from ?movie3d()

library(rgl)
 open3d()
 plot3d( cube3d(col="green") )
 M <- par3d("userMatrix")
 play3d( par3dinterp( userMatrix=list(M,
                                      rotate3d(M, pi/2, 1, 0, 0),
                                      rotate3d(M, pi/2, 0, 1, 0) ) ), 
         duration=4 )
movie3d( spin3d(), duration=5 )

and then I get the following message: 

Writing movie050.png 
Error in movie3d(spin3d(), duration = 5) : ImageMagick not found

which if I am correct means that R can not see ImageMagick (i have in the ImageMagick in the path variable: 
C:\Program Files\ImageMagick-6.5.6-Q16;;%GTK_BASEPATH%\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\jEdit)
I have found some earlier post with apparently  the same problem, but no solution.
Can anyone tell me what i am doing wrong?
Thank you very much and have a great day ahead!
