Can a single random number be generated in R? I have an exercise that wants to simulate coin tosses, and I cannot seem to find a good example of the use of random number generation in R. Any help? Joshua Gramlich Chicago, IL

Is anyone using R with postgres? I'd like to do so, but cannot seem to find any reasonable explanation of how to do so. Joshua Gramlich Chicago, IL

...e been created? For instance, I've a simple function that plots a table, but I'd like to go back and add more parameters to the barplot call. Is there a way to change this function without completely starting from scratch? Other than storing the code in a file and re-running it? Joshua Gramlich Piocon Technologies Chicago, Illinois USA

I think this may be a histogram, but I'm not sure. Can anyone tell me how to replicate this graph in R? http://www.ginworks.com/images/multitot.gif Thanks, Joshua Gramlich

I don't suppose it's possible to create a pie chart in R? I've got 1500 some odd elements in a frame that are valued at either -1, 0 or 1 and I'd like to find a reasonable way to represent the distribution graphically...any ideas? Joshua Gramlich Piocon Technologies Chicago, IL

Hello ... Does anyone know of a package (or other code) out there which has handled S4 classes in C? I realize that a lot of this stuff is fairly new in R-devel, so my assumption is no - but there seems to be some deviation from the green book that is really throwing me off, and I'm looking for some sort of front-to-back example.

...share that would load this environment up for a new R user for this dataset. If any of you wouldn't mind taking the time explaining how you would go about doing something like this, I would appreciate it. Also, does anyone know if one can set VI keybindings in an R shell?

Hello together, i want to run LCDHype in Linux under wine, because there is no adequate other program that supports graphically LCD-Displays. I already opened a discussion in the forum of LCDHype (sorry - is in german language): http://lcdhype.condense.de/index.php?showtopic=4963 I already found an older version (V 0.6) of LCDHype that installs and the frontend is up and running.
