Plot Publication-Grade Gene and Genome Maps
Description
Draws gene or genome maps and comparisons between these, in a publication-grade manner. Starting from simple, common files, it will draw postscript or PDF files that can be sent as such to journals.

The only plotting function is plot_gene_map
, which
produces link[grid]{grid}
graphics. Data is composed mainly of
DNA segments (dna_seg
) objects, which represent
collections of genes or segments of genomes, and of
comparison
objects, which are the pairwise comparisons
between the dna_seg
s. Data can be read from files (see
read_functions
) or from R objects like
data.frame
s or list
s, with dna_seg
and
comparison
conversion functions.

Examples
## simple example
## dna segments
## data.frame with several genes
names1 <- c("feat1", "feat2", "feat3")
starts1 <- c(2, 1000, 1050)
ends1 <- c(600, 800, 1345)
strands1 <- c("-", -1, 1)
cols1 <- c("blue", "grey", "red")
df1 <- data.frame(name=names1, start=starts1, end=ends1,
strand=strands1, col=cols1)
dna_seg1 <- dna_seg(df1)
is.dna_seg(dna_seg1)
## with only one gene, or two, and merging
gene2a <- dna_seg(list(name="feat1", start=50, end=900, strand="-", col="blue"))
genes2b <- dna_seg(data.frame(name=c("feat2", "feat3"), start=c(800, 1200),
end=c(1100, 1322), strand=c("+", 1),
col=c("grey", "red")))
dna_seg2 <- c.dna_seg(gene2a, genes2b)
is.dna_seg(dna_seg2)
## reading from file
dna_seg3_file <- system.file('extdata/dna_seg3.tab', package = 'genoPlotR')
dna_seg3 <- read_dna_seg_from_tab(dna_seg3_file)
is.dna_seg(dna_seg3)
## comparison
## from a data.frame
comparison1 <- as.comparison(data.frame(start1=starts1, end1=ends1,
start2=dna_seg2$start,
end2=dna_seg2$end))
is.comparison(comparison1)
## from a file
comparison2_file <- system.file('extdata/comparison2.tab',
package = 'genoPlotR')
comparison2 <- read_comparison_from_tab(comparison2_file,
color_scheme="red_blue")
is.comparison(comparison1)
## plot
plot_gene_map(dna_segs=list(dna_seg1, dna_seg2, dna_seg3),
comparisons=list(comparison1, comparison2))
