Dear Authors,
Thanks for reading this email. I'm a graduate student from China (PRC) and
learning the R at present. Now I have some questions to ask you as I have met
some strange problems during installing and running the R environment, which
can not be found in the "R FAQ" document (or just I can not find them).
It might be useful that I gived you the information of my operation system and
hardwares. I am using R on a Mandrake Linux 10.1 operation system on a PC
platform parchased from IBM company. The mainboard of my computer is Intel
915PG, that means it has an integrated graphic accelerator.
The first question is about the error occurs during my installation. Following
the "R Installation and Administration" manual, I successully downloaded the
latest version of R, unziped the file, and also completed the progress
"./configure" and "make" successully. By the way, I managed to install a
developmental package of Linux named "r77", which may be a FORTRAN
developmental package, before installing the R environment into my computer.
However, an error occured when I type the commond "make check" or "make check
FORCE=FORCE" or "make check-devel", and the warnings displayed are written
below:( Somewords are translated from Chinese into English by myself)
"running code in 'graphics-Ex.R' ...make[4]: *** [graphics-Ex.Rout] error 1
make[4]: Leaving directory `/home/zhengqi/R_HOME/R-2.1.1/tests/Examples'
make[3]: *** [test-Examples-Base] error 2
make[3]: Leaving directory `/home/zhengqi/R_HOME/R-2.1.1/tests/Examples'
make[2]: *** [test-Examples] error 2
make[2]: Leaving directory `/home/zhengqi/R_HOME/R-2.1.1/tests'
make[1]: *** [test-all-basics] error 1
make[1]: Leaving directory `/home/zhengqi/R_HOME/R-2.1.1/tests'
make: *** [check] error 2"
What's the mean of the error messeage listed up? Why it happens in my computer?
Which kind of problems is it, software's or hardware's? I just ignored the
mistakes, as it says in your installation manual that this kind of failures "is
not necessarilly problems as they might be caused by missing functionality",
until I met with the following problem.
The second bug occured when I was doing some ordinary statistical work. Suppose
v1 is a numerical vector of length(v1)==20; further suppose
> v1 <- c(1:20).
When I type the command
> lines(density(v1))
or
> rug(v1)
simillar errors take place, and it prompts the following messages below: ( some
key words of the promption are translated into English by myself)
For the first command, it warns:
"error occurs at: plot.xy(xy.coords(x, y), type = type, col = col, lty = lty,
...) :
'plot.new' hasn't been called yet"
and for the second command, it warns:
"error occurs at: axis(side, at = x, lab = FALSE, lwd = lwd, ...) :
'plot.new' hasn't been called yet"
Besides: warnings:
some values will be clipped in: rug(v1)"
These are some description of the problems I met during the installing and
running the R environment. And if you need more detail description of those
problems, please let me know and I will gather any information about them as
much as possible.
Waiting for your reply!
Best wishes to everyone!
Sincerely yours,
Anonymous user from Beijing, China
