[R] Plots: I've deleted axes, now to delete space

Sun May 22 14:41:58 CEST 2011

Hi Adele,

it was not my intention to critizise you for posting your question. You 
are totally free to post whatever question you like and the reciepient 
is then free to answer it or not. I wanted, however, to demonstrate to 
you that it would have been easier in my opinion to research some of the 
very nice tutorials available on the internet to answer your question 
regarding the dev.off() function. I totally did not want to discurage 
you (or anybody else) from using r-help. It just happens quite often 
that people post questions where one has the impression that researching 
documentation or the list archive would have led them to the solution. 
In such cases (as for example yours) I usually point the poster to these 
resources.

So, feel totally welcome to use the list for posting all questions you 
might have. It is then up to the others on the list to decide for 
themselves whether they want to anwer your question or whether to 
consider the questnion to be too basic!

Best regards

Jannis

I am not an expert at deciphering the documentation though and I post here because I did in fact read the documentation, do extensive google searches, ask friends/collegues and still find no answer. This forum is not a first resort for me. There is a very bad rep of R forums being notoriously harsh on new comers. I myself do not like when people do not try. In order to avoid this harshness (I have not found this forum any more harsh than your everyday educated R user), I do my own research and ask a question when I get stuck. I realize that people still are upset by my ignorance and that is their choice. I will get better and better at R and less and less likely to run into any of these issues. I am not a programmer or statistician by trade, but I am a learner and thus will continue to improve.

In general the dev.copy approach can be a quick and easy solution for a simple graph, but plotting directly to the file tends to work better if you want a quality graph in the file.
