In iaaka/visutils: QC, analyse and visualize visium

Plot heatmap with numbers

Description

Wraps image functions

Usage

imageWithText(
  d,
  t = NULL,
  digits = 2,
  text.col = NULL,
  xaxlab = rownames(d),
  yaxlab = colnames(d),
  centerColors0 = FALSE,
  las = 2,
  text.xadj = 0.5,
  colAnns = NULL,
  rowAnns = NULL,
  colAnnCols = NULL,
  rowAnnCols = NULL,
  col = hcl.colors(100, "YlOrRd", rev = TRUE),
  rowAnnWidth = 0.7,
  colAnnWidth = 0.7,
  annSpacer = 0.1,
  ...
)

Arguments

d	matrix to be plotted
t	text to be ploted on top of image (rounds d by default)
digits	number of digits retained under rounding of d
text.col	color for text
xaxlab, yaxlab	axis labels, dimnames(d) by default
centerColors0	logical, specifies whether 0 should be considered as palette center (makes sense for correlation matrices)
las	orientation of axis labels (see las in ?par)
text.xadj	text adjastment by x
colAnns, rowAnns	list (or matrix of columns) of column (row) annotation to be shown by color
rowAnnWidth, colAnnWidth	size of colour annotations as fraction of plot area
annSpacer	spacer between heatmap and annotation as fraction of plot area
...	other options to be supplied to image
colAnnsCols, rowAnnsCols	colors to be used for col (row) annotation. Defined by char2color if null.
legend.cex.at, legend.col.at	values to be used in legend, set both to have two independent legends for size and colour
legend.cex.title, legend.col.title	titles of legends

Examples

par(mar=c(10,6,1,1),bty='n')
imageWithText(mtcars[1:4,1:3],rowAnns=list(r1=c(1,1,2),r2=c('a','a','a')),rowAnnCols=list(r1=c('1'='red','2'='blue'),r2=c(a='green')),colAnns = list(c1=c(1,1,1,2),c2=c(2,1,2,1),c3=c('a','b','b','b')))
