Hi I want to simplify my problem into a prototype, how to write a function to get all the object in your current environment, e.g. .GlobalEnv, and print their mode? For 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

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.

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

Hi dear all I am currently using Ubuntu 9.10 (karmic) and R 2.10, I can find a R release that support "karmic" in cran under ubuntu directory, 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? Thanks in

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]

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

Hello, Can anyone please suggest any packages in R that can be used to overlay gene expression data on SNP (affymetrix) copy number ?

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

Dear All, I came across an error message recently when constructing a reference class, an example is attached below, it looks like only if I call a specific method in advance, otherwise it cannot be found in defined method without using .self, this make it difficulty that sometimes in my initialize method, I need to call other method defined in the same reference class, the workaround for this is

Hi dear all, I cannot find ggExtra source code or install it by install.packages("ggExtra", repos="http://R-Forge.R-project.org") I am really interested in one of the functions inside called "align.plots", but cannot find the package on-line. Do I miss something? or is there any function similar to that I can easily align multiple plots on the same x-axis on one

Hi Ian, Per your suggestion, I reinstalled R 2.9.0, then I reinstalled ggplot2 on top. The problem persists.

Dear R-users, I am trying to make a plot with ggplot-geom_tile(), but cannot remove some unwanted (white) lines through my plot.

While running a long script which source()s other scripts I get the following warning: Warning message: In t(object$S[[1]]) : bytecode version mismatch; using eval I cannot replicate it if I run the sourced files line by line though...

Dear All, Thank you kindly for such detailed replies. I was looking to overlay data using algorithms so that i am able to tell which genes are differentially expressed due to changes in copy number. I did a pubmed search and found only 7 literature pieces all of which use in-house algorithms. I am yet to explore Gviz since it wouldn't work on R 2.14, would try it after upgrading to R 2.15.
