semi-transparency not supported in devel R? "alpha" cannot be specified in qplot()
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:

Bezier curve in R?
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.

R for ubuntu 10.04?
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

Reference Class error message: may be caused by lazy evaluation?
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

ggExtra package installation fails
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

Select single column, preserve name?
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

FW: [BioC] Overlay Gene Expression on SNP (copy number) data
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.

R GUI
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

R crashes with large vectors
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

eapply weirdness/bug
The following looks like an 'eapply' bug to me:

t/subtest> e$tempo <- quote( 1+'hi')
t/subtest> lapply( ls( e), function( x) length( get( x,e)))
[[1]]
[1] 3
# seems reasonable-- e$tempo is a 'call' object of length 3

eapply() fails on baseenv() (PR#8761)
eapply() works on most environments, but not on baseenv(). For example,
> x <- 1
> eapply(globalenv(), function(x) x)
$x
[1] 1
> eapply(baseenv(), function(x) x)
list()
I'm probably not going to have time to work on this before 2.3.0, but I
don't think it's really urgent; if no one else fixes it first I'll do it
after the release.

ls() and classes
Dear R People:
I want to get the class of all of the objects in my directory.
I was trying:
do.call(class,list=ls())
but got an "unused argument error".
I'm sure it's simple, but I'm just not seeing it.
Any help would be much appreciated.
Sincerely,
Erin
