positionTextBoxDriver {textBoxPlacement}

positionTextBoxDriver

Description

Driver to compute x and y coordinates for placement of text box based upon the values of the function to avoid running into the graph line and avoid overlapping with other overlay curves

Usage

positionTextBoxDriver(
  text,
  x,
  y,
  xPos,
  nApprox = 10,
  xList,
  yList,
  stag = FALSE,
  offset = 0,
  verbose
)

Arguments

text

character string text to insert in plot

x

numeric vector of x values

y

numeric vector of y values

xPos

numeric x position for text box

nApprox

integer number of intervals to interpolate between x data points

xList

list whose components are numeric vectors of the x values for overlaid curves

yList

list whose components are numeric vectors of the y values for overlaid curves

stag

Boolean TRUE if this plot has staggering added to curves

offset

numeric vector of offsets added to each curve

verbose

Boolean if TRUE print informative or diagnostic messages to console

Value

returns a numeric vector c(yReal,yAdj) where xTry is an x value at which the text box will fit without overlapping another overlay curve, or returns -1000000 for failure

Examples

positionTextBoxDriver(text="TEXT ME",x=xList1[[1]],y=yList1[[1]],
  xPos=1,nApprox=10,xList=xList1[-1],yList=yList1[-1],stag=FALSE,offset=0,verbose=TRUE)
