R version 2.8.1 (2008-12-22) on Linux 64-bit
I am trying to run 'rulefit' function (Rule based Learning Ensembles). but I
got the following error -
rulefit(x,y)
Warning: This program is an suid-root program or is being run by the root
user.
The full text of the error or warning message cannot be safely formatted
in this environment. You may get a more descriptive message by running the
program as a non-root user or by removing the suid bit on the executable.
xterm Xt error: Can't open display: %s
xterm: DISPLAY is not set
Error in file(file, "r") : cannot open the connection
In addition: Warning message:
In file(file, "r") :
cannot open file '/root/_rulefit/rfstatus': No such file or directory
------------------------------
On windows R 2.10, I got this run successfully. So I am wondering whether it
is due to my R older version on Linux.
Well, may be, both R versions are old and the release candidate for
R-2.12.0 is out, hence please use that one for now and witch to the
release version next week.
For your original question: Looks like you had some terminal without X
forwarding, i.e. R was not able to open an x11 window in ordert to
present a plot.
