apache - Unable to brew using R -

-

httpd.conf file config brew this:

<directory /usr/local/apache2/htdocs/brew>         sethandler r-script         rhandler brew::brew         defaulttype text/html </directory>

under brew folder, have file:

<html> <body> <% library(cairo) filename <- paste(tempfile(tmpdir='/usr/local/apache2/htdocs'), '.png', sep='') cairopng(filename) x<-1:10000 plot(x, type="l", col="red") dev.off() %> <img src="<%=filename%>"/> </body> </html>

i set permission 777 on safe side, @ least until working.

when call http://localhost/brew/temp.brew, see file being generate under htdocs folder browser not displaying image, broken image. missing? again group.

when try brew simple this, print out on browser:

<% x<-1:1000 print(x) %>

this may apache related. when this:

 <%=filename%>

i on browser:

/usr/local/apache2/htdocs/file199c5ea9644c.png

my apache home directory /usr/local/apache2/htdocs, when full path provided in img src="<%=filename%>" sees /usr/local/apache2/htdocs/filename.png, apache dont know is. ideas?

the local file name, full, known server (apache): client (your web browser), need url or relative path. in particular, /usr/local/apache2/htdocs prefix should no longer there.

try replacing 

<img src="<%=filename%>"/>

with 

<img src="<%=gsub('/usr/local/apache2/htdocs', '', filename)%>"/>
