similar to: Creating images without X11

Dear Colleagues, We are attempting to create trees using R with our Ruby on Rails application. However, we are running into a problem involving the creation of the graphic. We would like them to be in either jpg or png format so that users can save, but due to a lack of control over our sever we are unable to start X11 server. Is there a way to create these images without using X11 server?

To whom it may concern: My name is Jillian Weinfeld. I am currently and undergraduate student at New York University and working at Mount Sinai School of Medicine doing research with epilepsy patients.

You can save as png like this too: library(ggplot2) data=data.frame( ?

I'm completely new to R, and I'd like to do something like this: > x=c(1,2,3) > plot(x,x) At this point, R creates a file "Rplots.pdf", since the default device is PDF and the default filename is "Rplots.pdf". I know I can set the default device like this: > options(device="png") But is there a way to set the default device's

I''ve heard that using LIKE is very slow, but I see it being used a lot in examples, blogs etc. Is it really that bad? Since Rails doesn''t directly support Fulltext search, this is the easiest way to get searching done, right? Or are there any other easier ways? I''m using acts_as_indexed right now, but it still doesn''t do what LIKE does.

Dear R user, I try to build R-2.8.1 on SunOS 5.9, and use following command: CC="cc -xarch=v9" CFLAGS="-xO5 -xlibmil -dalign" F77="f95 -xarch=v9" FFLAGS="-xO5 -xlibmil -dalign" CXX="CC -xarch=v9" CXXFLAGS="-xO5 -xlibmil -dalign" FC="f95 -xarch=v9" FCFLAGS="-xO5 -xlibmil

Dear R users I am analysing data from a group of twins and their siblings. The measures that we are interested in are all correlated within families, with the correlations being stronger between twins than between non-twin siblings. The measures are all calculated from survey answers and by definition have limited ranges (e.g. -5 to +5), though within the range they are approximately normally

I am not understanding something about generating PNG plots. I have tried several ways to obtain something other than a transparent background, but nothing I've done seems to change the background. For example: dev.print(png, width=800, height=600, bg='red', filename='example.png') which I thought would give a red background, simply gives the same transparent background I

What is the difference between xorg-x11-fonts-75dpi and xorg-x11-fonts-100dpi? Under what circumstances would one want to use the 75dpi version versus the 100dpi version? If you have both installed, does the xorg server just pick the one that it considers best based on some criteria? Should you have both installed? Is anything gained by having both installed? As you can see I don't know
