plotFeatures(gff, chr, xlim, strand, vpr, featureColorScheme=1, 
             featureExclude=c("chromosome", "nucleotide_match", "insertion"),            
             featureNoLabel=c("uORF", "CDS"), ...)

Arguments

gff

data frame with genome annotation from the GFF file.

chr

integer of length 1 specifying the chromosome to plot the features for.

xlim

integer of length 2 with start and end coordinates (in bases) for plotting.

strand

character scalar which should be set to either + or - to indicate which strand of DNA to plot the features from.

vpr

which viewport to plot the features in.

featureColorScheme

numeric scalar, used to select a color scheme for the boxes representing genomic features such as coding sequences, ncRNAs etc. Currently the only value supported is 1.

featureExclude

character vector of names of feature types (in gff) that should not be plotted. Default is "chromosome", "nucleotide_match" and "insertion". Additional possible candidates include: "ARS", "repeat\_region", "repeat\_family" and "nc\_primary\_transcript".

featureNoLabel

character vector, names of feature types (in gff) that should not be labelled with their names (if they are plotted).

...

additional arguments.

Details

This function is called by plotAlongChrom when the gff argument has been specified. It should not be called directly by the user.
