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.
