OutbreakTools implements basic tools for the analysis of Disease Outbreaks.
obkData to store case-base outbreak data. It also provides a function,
plotggphy, to visualize such data on the phylogenetic tree.
library(OutbreakTools) data(FluH1N1pdm2009) attach(FluH1N1pdm2009) x <- new("obkData", individuals = individuals, dna = FluH1N1pdm2009$dna, dna.individualID = samples$individualID, dna.date = samples$date, trees = FluH1N1pdm2009$trees) plotggphy(x, ladderize = TRUE, branch.unit = "year", tip.color = "location", tip.size = 3, tip.alpha = 0.75)
ggtree can parse many software outputs and the evolution evidences inferred by these software can be used directly for tree annotation. ggtree not only works as an infrastructure that enables evolutionary data that inferred by commonly used software packages to be used in R, but also serves as a general tree visualization and annotation tool for the R community as it supports many S3/S4 objects defined by other R packages.
phyloseq class defined in the phyloseq package was designed for microbiome data.
phyloseq package implemented
plot_tree function using
ggplot2. Although the function was implemented by
ggplot2 and we can use
scale_color_manual etc for customization, the most valuable part of
ggplot2, adding layer, is missing.
plot_tree only provides limited parameters to control the output graph and it is hard to add layer unless user has expertise in both
ggtree, Methods in Ecology and Evolutionに掲載されたのか。オープンアクセスっぽいな。https://t.co/JlET18BSZv— ホクソピペット (@siero5335) August 16, 2016
MeSH (Medical Subject Headings) is the NLM (U.S. National Library of
Medicine) controlled vocabulary used to manually index articles for
MEDLINE/PubMed. MeSH is comprehensive life science vocabulary. MeSH has
19 categories and
MeSH.db contains 16 of them. That is:
Leading edge analysis reports
Tags to indicate the percentage of genes contributing to the enrichment score,
List to indicate where in the list the enrichment score is attained and
Signal for enrichment signal strength.
It would also be very interesting to get the core enriched genes that contribute to the enrichment.
