r - How to configure FastRWeb to use RServer built-in web server -

-

i'm new rserve (and fastrweb). installed rserve 1.7.0 want use built-in webserver. have apache running on machine want run rserve/fastrweb on custom port.

i did cd /usr/local/lib/r/site-library/fastrweb;sudo ./install.sh, created /var/fastrweb/ directory tree.

i'm not seeing configuration file mentions port. default /var/fastrweb/code/rserve.conf looks this:

socket /var/fastrweb/socket sockmod 0666 source /var/fastrweb/code/rserve.r control enable

i'm guessing means uses unix sockets, default? think question exactly have put in (and remove from) file to, say, have listen on tcp port 8888? , there else need do? (i want able connect other machines, not localhost.)

possibly related, i've looked @ /var/fastrweb/web/index.html , contains javascript going connect /cgi-bin/r/ path specific when using apache, or going fine, as-is, when using rserve?

there explanation of setting port in rserve 1.7.0 release announcement. therefore, @ top of rserve.conf, added line: http.port 8888 used start script (as root), start it.

this got me halfway http://127.0.0.1:8888/ works, gives me page says:

error in try(.http.request("/", null, null, c(48, 6f, 73, 74, 3a, 20,  :    not find function ".http.request"

the second half of solution add top of /var/fastrweb/code/rserve.r:

library(fastrweb) .http.request <- fastrweb:::.http.request

then start things going running /var/fastrweb/code/start. there no default handler, can test http://127.0.0.1:8888/info. or more interesting example http://127.0.0.1:8888/example1.png (to view chart) or http://127.0.0.1:8888/example2 (to view mix of html , chart)

note: did not delete or edit other configuration working. means have unix socket listening. if not needed remove 2 lines rserve.conf file.

if want listening on ip addresses, not localhost, add remote enable rserve.conf file. note: make sure understand security consequences before opening server world.

so, after 2 changes, /var/fastrweb/code/rserve.conf file looks like:

http.port 8888 remote enable source /var/fastrweb/code/rserve.r control enable
