...example, if I have object a,b,c... in my environment, a=1;b='test';c=matrix(0,3,3)..... I want to write a function myfun(), when I run myfun(), this retrieve all the objects in my environment automatically and print their mode or class one by one.

Hi dear all, I am wondering if there is a function existing in R that did the quadratic bezier curve interpolation? I hope to generate a bezier curve based on three sets of points: two end of the line and a control point. Thanks in advance.

...rectory, I plan to update my laptop to Ubuntu 10.04 after April 30, since I have to use some new features or new version in it, e.g. QT 4.6, I don't know if there is going to be a R release that will support this newly released Ubuntu?

I recently started using ubuntu 9.10 and I am using gedit editor and R plugin for writing R code. To install any package I need to do: $ install.packages() //window pop-up for mirror selection //then another window pop up for package selection. After this as long as I am not exiting, the function of the newly installed packages are available. After I exit (i use to put 'no' in 'save

I'm a very new user of R, The problem I got is when I have lots of data table, 3 columns and 100 rows assigned to a variable x. how can I transform the table into a external file excel or other files without losing any information. So that make the data look nicer. -- View this message in context: http://r.789695.n4.nabble.com/How-to-extract-data-table-tp2075750p2075750.html Sent from the R

..., it's not the case that I can make it a simple facet, it's always alignment of multiple tracks. And I don't really want to write my own hack function(and don't know how yet) to do that, if there is already a nice function for the same purpose~ Thanks~ Tengfei -- Tengfei Yin MCDB PhD student 1620 Howe Hall, 2274, Iowa State University Ames, IA,50011-2274 [[alternative HTML version deleted]]

Hi, list- ?? I've got a large list of multi-column data and I'd like to filter it according to a threshold, such as, "show me the values that are above 0.4 for each line." For instance, if the line of data were: > line v1 v2 v3 v4 v5 v6 v7 v8 v9 1 -0.32 0.66 -0.35 -0.82 0.38 0.66 -0.02 -0.11 -0.64 I can do this > line[,line >= 0.4]

Good afternoon, I have been experiencing a lot of crashes working with large vectors in R. Specifically, I am using XTS of length of minimum 120k elements. My problem is that I cannot display the vector (otherwise R crashes), I cannot plot it either (otherwise R crashes). That could be solved by reducing the amount of points. However, I have been performing some statistical opreations on is

I am really new with R Graphical user interfacefunctions. I am developing a software package to calculate pKa (biochemistry) but I want to make it look aesthetically pleasing and make it user friendly. I have heard that R has some GUI (Graphical user interface) and you can do some really cool stuff out there. What are the limitations and what are some resources for help. I have found a couple of
