I get the following errors when running the EBImage introductory sample code: >################################################### >### code chunk number 11: math2 >################################################### >lena4 = lena[299:376, 224:301] Error in slot(lena, ".Data")[299:376, 224:301] : incorrect number of dimensions >lena5 = lena>0.5 >lena6 = t(lena) Error in t.default(lena) : argument is not a matrix >print(median(lena)) [1] 0.3803922 > Can any when help me understand what is going on? Did something go from S3 to S4 that changes the way this code should be written? Thanks, Rob [[alternative HTML version deleted]]

So I wonder if it is a problem with the external dependencies GTK+ and ImageMagick. I assume you installed them as described here: http://bioconductor.org/packages/release/bioc/vignettes/EBImage/inst/d oc/EBImage-installation.pdf What happens if you open a command window and type echo %PATH% also, what about this command: convert ?

To answer your follow-up queries: C:\Users\rbaer>echo %path% C:\GTK\bin;C:\Program Files (x86)\ImageMagick-6.7.8-Q16;C:\Windows\system32;C:\Windows;C:\Windows\ System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\ggobi; Typing 'convert' at the command prompt produces an extensive list of what appear to be possible flags for imageMagick I am using a 64-bit Windows 7 (Enterprise edition) OS but the 32-bit R when I get this error. I think both the ImageMagick and GTK+ are designed for 32-bit, and should therefore match the R I'm using. Just for clarification, the whole vignette runs just as expected EXCEPT for code chunk 11 where lena4 and lena6 are supposedly created and code chunk 12 when lena4 and lena6 are supposedly saved (because they didn't create. lena5 works fine. Both fail with the errors indicated above. The rest of the code runs and produces images as expected (or at least without error and with images appearing and/or getting saved). lena6 is created in the vignette code as a transpose of lena (an "image" object) ostensibly because it is not a matrix. It appears that this line of code is using t.default suggesting that this generic function doesn't have an "Image" method. Should it? Would this be a method supplied by EBImage or some other package? This makes me suspect some sort of R issue, but I don't know enough about GTK+ or ImageMagick to eliminate issues there. # Version notation.

Dear Robert, The issue you're mentioning seems to be a Windows-specific bug that we don't see when building the Linux version of the package. I'm having a look.
