Add text to points on plot

Description

This function allows to add custom text as lables to points on standard xy-plot.

Usage

.addTextToPoints(
  x,
  paramLst = NULL,
  labels = NULL,
  cex = NULL,
  col = NULL,
  adj = "auto",
  callFrom = NULL,
  silent = FALSE,
  debug = FALSE
)

Arguments

x	(matrix, data.frame) coordinated of ponts on plot
paramLst	(list) additional parameters for plotting (priority over separate cex or col), otherwise names displayed will be taken from 'labels' or rownames of coordinates 'x'
labels	(character) the text to be displayed (has not priority over 'paramLst'), if nothing valid found numbers will be displayed
cex	(character) (numeric) size of text, as expansion factor (see also cex in par)
col	(character or integer) use custom colors
adj	(character) values other than 0,0.5 or 1 will lead to 'auto' where text is displayed only to left of sufficient space available
callFrom	(character) allow easier tracking of messages produced
silent	(logical) suppress messages
debug	(logical) display additional messages for debugging

Value

This function make a plot and may retiurn an optional matrix of outlyer-data (depending on argument getOutL)

Examples

set.seed(2019); dat1 <- matrix(round(runif(30),2), ncol=2)
plot(dat1)        # traditional plot
.addTextToPoints(dat1, labels=letters[1:nrow(dat1)])
