Hi dear all, In my laptop(ubuntu 11.10 64bit), I maintained a released R (2.14) and a developmental R, I can specify qplot(..., alpha = ) in R 2.14 , but when I try to use transparency in developmental R, I got a warning message and the plot is clearly not I want. minimal example: > qplot(data = mtcars, x = mpg, y = cyl, alpha = cyl) Warning message: In grid.Call.graphics(L_points, x$x, x$y,

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.

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

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

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?

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 I am trying to read genbank est flat files. Is there any function in R to do that. I was looking for something similar to SeqIO.parse(input_handle, "genbank") in bioPython that convert the genebank sequence into fasta sequence. (One option is to call biopython from R but I am not familiar with python functions so I want to avoid that and I am keeping it as last resort) Thanks and

Hi, I am trying to call a C function, that I wrote to parse a flat file, into R. The argument that will go into this function is an input file that I need to parse and write the desired output in an output file. I used some hit and trial approach but i keep on getting the "file not found" or "segmentation fault" error. I know that the error is in passing the argument but I

Hi How to access the values in the output that is an object of S4 type. I tried to access using subset ( [ ] ) but it is not allowed. Any clue??
