search for: ggbio

Hi, I've noticed an issue with S4 methods and namespaces which only arises in particular, difficult to reproduce configurations. One example is the ggbio package in Bioconductor, which currently emits these warnings when its namespace is loaded: ---------------------- library(ggbio) Loading required package: ggplot2 Attaching package: ‘ggbio’ The following object(s) are masked from ‘package:ggplot2’: geom_rect, geom_segment, stat_identity,...

...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. Other package - ggbio , work on an input 'Object'. I am not able to figure out what to provide as object - gene expression data matrix as whole and or SNP log2 normalised ratios? Any more help or thoguhts here will be greatly appreciated. Thanks a ton ! -E From: Tengfei Yin [mailto:yintengfei@gmail.com] Sent...

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

Hello, I am trying to create a simple Manhattan plot for a small list of 200 SNPs spread out in the genome in different genes. I have tried different functions (using ggplot2 and a function created by Stephen Turner, mhtplot etc.)-none of them work smoothly. Does anyone have a simple way to create the plot (not for all 22 chromosomes)- with the x axis showing the genes name and not the
