Re: [R] histogram in GNU R....

[Peter Langfelder]

A simpler short term solution is to execute dev.off() and look for the plot
in file Rplots.pdf in the current directory. Depending on the OS of the
local computer, you should be able to point a file browser at the EC
instance and simply click the file to open in in a pdf viewer on the local
machine.

You may have to install X11 stuff to your ec2 instance.  E.g., googling for
"ec2 X11 forwarding" showed things like the following:

The above is all I needed to get X11 forwarding working over ssh

When ssh-ing to the instance, use the -X flag

Re: [R] histogram in GNU R....

[MacQueen, Don via R-help]

In addition to the other suggestions, try typing

  x11()

before using hist().

That *should* start a graphics window. If it does not, then type

  capabilities()

and see if "X11" is TRUE.

whats going on?

How can I circumvent the help of histogram(which is not available in GNU 
R)? summary(xht) would help, but not much. Any other function that can give 
information, in LINUX R, that a histogram gives, in LINUX CLI?

Very many thanks for your time and effort...
Yours sincerely,

Re: [R] histogram in GNU R....

[peter dalgaard]

You are most likely plotting to a non-screen device. Check dev.list() after the 
hist(), and then the documentation for that device. It's probably pdf, and 
after quitting R, you should find that a file Rplots.pdf has been created.

Yes, hist() returns its value invisibly (try typing "? invisible" in
the R prompt without the quotes), which means that you don't see it, but
you can assign it to a variable and then view as usual:

> xht <- c(1,2,3,4,5,6,7,8,9,10)
> hxt <- hist(xht)
> hxt

You can also use the following trick:

> (hist(xht))

to see the invisible returned value without assigning it to a temporary
variable.

> But there is no pop up screen with a histogram, and nothing else...

As to why you cannot see a plot, it depends a lot on your setup. For
example, how exactly do you connect to the R instance running at AWS?
If you use plain SSH from your own Linux machine, try `ssh -X` to allow
the remote server to connect to the X graphics system on your machine
and display windows (alas, it gets very slow). What does `dev.cur()`
show after you run `hist(xht)`? On my machine, when I start R with no
available X connection, it automatically switches to the
non-interactive `pdf` graphics device; all plots get redirected to the
`Rplots.pdf` file in the current directory. Perhaps you can download
that file from the EC2 instance and view it locally?
