hl_plot: hl_plot() function

In RNAdecay: Maximum Likelihood Decay Modeling of RNA Degradation Data

Description

Plots RNA half-life distribution with select half-lives of select RNAs as large arrows colored by treatment using the ggplot2 package.

Usage

hl_plot(
  geneID,
  gene_symbol = "",
  df_decay_rates,
  hl_dist_treatment,
  hl_treatment,
  arrow_colors = NA,
  arrow_lab_loc = c("key"),
  x_limits = log(2)/c(0.25, 0.00045),
  x_breaks = c(5, 1:12 * 10, 180, 240, 300, 360, 420, 480, 720, 1080, 1440),
  x_tick_labels = c("5", "10", "", "30", "", "", "60", "", "", "", "", "", "2h", "",
    "4h", "", "", "", "8h", "12h", "", "24h")
)

Arguments

geneID	single gene ID from data set (e.g. "AT3G14100") for which to plot data/model
gene_symbol	(optional) pasted to gene ID in plot label (e.g., "AT3G14100/UBP1C)
df_decay_rates	data.frame of modeling results with decay rate columns labeled as alpha_<treatment>
hl_dist_treatment	name of the treatment for which the background distribution will be plotted
hl_treatment	names of the treatments for which arrows indicating half-life will be plotted
arrow_colors	(optional) character vector of R colors; named with corresponding treatments
arrow_lab_loc	label arrows on plot ("plot") or in a key ("key")
x_limits	x-axis (half-life) limits in min; default is log(2)/c(0.25,4.5e-4)
x_breaks	x-axis (half-life) breaks/tick marks in min defaults to c(5,1:12*10,180,240,300,360,420,480,720,1080,1440)
x_tick_labels	x-axis (half-life) break labels, defaults to c("5","10","","30","","","60","","","","","","2h","","4h","","","","8h","12h","","24h")+

Value

returns a ggplot to be used with print; could also be modified using the syntax of ggplot2 e.g.'+geom_XXXX(...)'

Examples

p <- hl_plot(
geneID = rownames(RNAdecay::results)[4],
df_decay_rates = RNAdecay::results,
hl_treatment = c("WT","sov","vcs","vcs.sov"),

arrow_colors = c(WT = "#88CCEE", sov = "#CC6677", vcs = "#117733",vcs.sov = "#882255"),
arrow_lab_loc = "key",
gene_symbol = ""
)

print(p)
