Dear All I have just installed the package Ryacas, but getting the following:> library(Ryacas)Loading required package: XML> yacas("1/2 * 3/4")[1] "Starting Yacas!" Error in socketConnection(host = "127.0.0.1", port = 9734, server = FALSE, : unable to open connection In addition: Warning message: 127.0.0.1:9734 cannot be opened> /usr/lib/R/library/Ryacas/yacdir/R.ys(1) : File not found >I am using Fedora Core 6 (Linux), R 2.4.0 and Yacas 1.0.62. Any ideas? Thanks in advance, Paul

I have followed the instructions given at: http://groups.google.com/group/comp.os.linux.networking/msg/656bbead5059fc07 as suggested at http://code.google.com/p/ryacas/ However, I still get the following: $ telnet localhost 9734 Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host: Connection refused $ Paul
You might try posting your problem on the comp.os.linux.networking group since it appears to be a configuration problem with telnet on your machine. If all else fails, you can try using the "system" method of connecting to Ryacas discussed on the Ryacas home page. That is not ideal since it will not give you any memory from one Ryacas call to the next but it will allow you to do command at a time Ryacas processing even without telnet. Note that you mus be using Ryacas 0.2-3 (which is located on google groups -- see links section on home page) and not 0.2-2 for that to work.
