send_data => invalid byte sequence in US-ASCII
...Some particulars:
I''m running gnuplot through a pipe to generate a plot in .png format.
(I''ve tested the code by writing its output to a file and displaying it
-- it works.) My Report model receives the .png image as a string:
class Report << ActiveRecord::Base
def imagedata
image = GnuPlot(@gnuplot_commands)
end
end
My Controller uses send_data() to serve up a page:
class ReportsController < ApplicationController
def plot
report = Report.find(params[:id])
send_data(report.imagedata, :type => ''image/gif'')
end...

Question on EBImage package

Possible bug(s) causing ggplot2 and XLConnect to crash recent builds of r-devel
...uot;rJava", "XLConnect", "XLConnectJars".
In this case executing library(XLConnect) cause the same response - "R Session aborted" with the information that "R encountered a fatal error".
These are not packages that I maintain. However, I have packages (imageData and dae) that depend on ggplot2 and it seems that this bug is preventing me from compiling the packages under the most recent builds, although I can build the packages under the build of the 2017-06-27 r72859 development snapshot of R.

Optional libraries (libtiff, etc) not found
I installed the (binary) biOps package, which can use libtiff and libfftw.
Then I used macports to install the libraries (in /opt/local/lib). But I
restart R and biOps still does not see the libraries.
I've tried adding symbolic links from /opt/local/lib to /usr/local/lib, I've
added /opt/local/lib to LIBRARY_PATH, LD_LIBRARY_PATH, and
DYLD_LIBRARY_PATH, and it doesn't work.
Do you
