plot DoOR responses as a point matrix

Usage

dplot_response_matrix(data, odor_data = door_default_values("odor"),
  tag = door_default_values("tag"), colors = door_default_values("colors"),
  flip = FALSE, fix = TRUE, bw = FALSE, point = FALSE, limits,
  base_size = 12)

Arguments

data

a subset of e.g. door_response_matrix

odor_data

data frame, contains the odorant information.

tag

the chemical identfier to plot (one of colnames(odor))

colors

the colors to use if negative values are supplied (range of 5 colors, 2 for negative values, 1 for 0 and 3 for positive values)

flip

logical, if TRUE the x and y axes will be flipped

fix

logical, whether to fix the ratio of the tiles when plotting as a heatmap

bw

logical, whether to plot b&w or colored

point

logical, if TRUE a point matrix instead of a heatmap will be returned (the default if you supply only positive values)

limits

the limits of the scale, will be calculated if not set

base_size

numeric, the base font size for the ggplot2 plot

Value

a dotplot if limits[1] >= 0 or a heatmap if limits[1] < 0

Examples

# load data
library(DoOR.data)
data(door_response_matrix)

# reset the spontaneous firing rate to 0
tmp <- reset_sfr(door_response_matrix, "SFR")

# plot heatmap / coloured tiles
dplot_response_matrix(tmp[10:50,], tag = "Name", 
 limits = range(tmp, na.rm = TRUE))


# plot dotplot
dplot_response_matrix(door_response_matrix[10:50,], tag = "Name",
                        limits = range(door_response_matrix, na.rm = TRUE))
#> Only positive values, returning b&w point plot.
