Hello all,
a friend has a problem with tiff() which I was unable to help
about. I
searched the error messages to no avail. When he tries:
tiff(filename = "FedeWhyDoesntThisBloodyWork.tif", width = 5,
height =
5, units = "cm", bg = "white", res = 1200)
Error in tiff(filename = "FedeWhyDoesntThisBloodyWork.tif", width =
5, :
unable to start device
In addition: Warning messages:
1: In tiff(filename = "FedeWhyDoesntThisBloodyWork.tif", width =
5, :
Unable to allocate bitmap
2: In tiff(filename = "FedeWhyDoesntThisBloodyWork.tif", width =
5, :
opening device failed
Same for
tiff(filename = "FedeWhyDoesntThisBloodyWork.tif", width = 20,
height =
20, units = "cm", bg = "white", res = 300)
Error in tiff(filename = "FedeWhyDoesntThisBloodyWork.tif", width =
5, :
unable to start device

This second example runs on my Mac (I did not try the first), so we
are
at loss why windows would not run the very same code. Any ideas? I
can
see that setting the resolution very high (as for the forst example)
might not work, but the *windows only* failure of the second
example is
strange. I suspect cairo *could* be an issue, but that's as far as
I can
guess on sobody else's intallation.
Does capabilities("tiff") return TRUE ?
I checked on the affected computer and both tiff and cairo capabiliies
return FALSE. How that is I would not know, it's a bog standard R
installation on windows XP.
