Took me a few days to get a reply from the student. The code he is running is:
library(ripa)
img<-readJPEG( "arthurs-seat.jpg" )
hist(fftImg(img))
I see the same error as the student on many systems. When I run
require(ripa) on the machine I mentioned before:
> require('ripa')
Loading required package: ripa
Loading required package: tcltk
Loading required package: parallel
>img<-readJPEG( "arthurs-seat.jpg" )
>hist(fftImg(img))
Error in .C("fftw_access_func", as.complex(img), as.integer(w),
as.integer(h), :
"fftw_access_func" not available for .C() for package "ripa"
If I should take the conversation off of r-help as I loop in the
package maintainer, please let me know.
Thanks,
Eric
