Hey all, I learned that using the equals sign "=" to assign objects is generally OK, but will not work in some cases. As I always use "<-" for assignments, I have not encoutered any problems. Could somebody provide an example or explanation, why getting used to "=" is not a good idea? Or is it? Thanks ahead, Berry ------------------------------------- Berry

Hello dear developers, I find myself often having the result of "range" oder "extendrange", which I want to create a sequence with. But "seq" needs two seperate arguments "from" and "two". Could an argument "range" be added? Otherwise I will have to create an object with the range (may come from a longer calculation), index twice from

hi, say I have consecutively numbered objects obj1, obj2, ... in my R workspace. I want to acces one of them inside a function, with the number given as an argument. Where can I find help on how to do that? Somebody must have been trying to do this before... Some keywords to start a search are appreciated as well. Here's an example, I hope it clarifies what I'm trying to do: obj1 <-

Hey all, I encountered a problem drawing a histogram. You can view the picture here: http://dl.dropbox.com/u/4836866/Bad_Histogramm.png What happens: the bars are drawn with different starting points, thus no straight zero-line is there. And bars are overlapping. (or sometimes apart from each other.) How it happens: hist(volcano, breaks=10) # and any other data This also happens with

Hello dear R-developers, two questions on an otherwise magnificent program: 1) Is there a way to set defaults for par differently than R offers normally? I for example would like to have las default to 1. (or in the same style, sometimes type in plot() could be "l" per default). Tthe following post desribes pretty much exactly that:

Hi all, I'm working on a function that reads online data that is only available to certain IPs. It then writes a subset of the data into a file. So whenever I'm logged in elsewhere or am not connected to the internet, I get an error, and the function is terminated. I want it to rather print a message into the file. Is there any way to test whether a connection can be opened? Analogous to

Hi, I'm curious about Tab stops in graphics: plot(1) text(1.2, 1.2, "Char\nMoreChar") works fine, but text(1.2, 0.8, "Char\tMoreChar") doesn't. Exporting with pdf tells me that the sign width is unknown. I'm not into informatics, so I don't know how a tabstop actually works. Is this at all possible in graphical commands as it is in write.table and the like?

Hey all, I was wondering about the order of execution of functions and found that, in fact, I should look at the topic of buffering output to the console. Which I did - below are some links of related topics, in case anyone wants to read up on it. I decided to change the concerning lines in the file "Rconsole" in the "etc"-folder to ?? ## Default setting for console

Can somebody with write privileges in bugzilla add the bug report? I can also do this myself, if somebody with the required privileges can create a user for me.
