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.

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 > line[,line >= 0.4]

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

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.

data.frame to list
Hi, I'm new to R, and I'm not a statistician (stunned silence). I am trying to do the following: 1. read in a 2-column data file, e.g. status new db green title "Most Significant Excursions" 2. end up with an R list such that I can write e.g. lst$title and have R return "Most Significant Excursions". I know I could do this by coding lst = list(title="Most
