trellis_rainfall_plot: Create a rainfall plot in a trellis structure

View source: R/plot_functions.R

Description

A trellis is a plot structure which allows space optimized multi-panel multi track plots. This function uses the package gtrellis developed by Zuguang Gu, also available at http://www.bioconductor.org/packages/release/bioc/html/gtrellis.html. The graphics in the tracks within a gtrellis plot are mostly drawn with functions from the package grid. Note that for technical reasons, the column indicating the chromosome MUST have the name chr and be the first column in the data frame supplied to the gtrellis functions. Therefore reformatting is performed in this function before calling gtrellis functions.

trellis_rainfall_plot(in_rainfall_dat, in_point_size = unit(1, "mm"),
  in_rect_list = NULL, in_title = "", in_CHROM.field = "CHROM",
  in_POS.field = "POS", in_dist.field = "dist", in_col.field = "col")

Arguments

in_rainfall_dat

Data frame which has to contain at least columns for chromosome, position, intermutational distance and colour information

in_point_size

size of the points in the rainfall plot to be created has to be provided with appropriate units, e.g. in_point_size=unit(0.5,"mm")

in_rect_list

Optional argument, if present, will lead to highlighting of specified regions by coloured but transparent rectangles

in_title

Title in the figure to be created.

in_CHROM.field

String indicating which column of in_rainfall_dat carries the chromosome information

in_POS.field

String indicating which column of in_rainfall_dat carries the position information

in_dist.field

String indicating which column of in_rainfall_dat carries the intermutational distance information

in_col.field

String indicating which column of in_rainfall_dat carries the colour information encoding the nucleotide exchange

Value

The function doesn't return any value.
