elimCloseCoord

Eliminate close (overlapping) points (in x & y space)

Description

elimCloseCoord reduces number of rows in 'dat' by eliminating lines where x & y coordinates (columns of matrix 'dat' defined by 'useCol') are identical (overlay points) or very close. The stringency for 'close' values may be fine-tuned using nDig), this function uses internally firstOfRepeated.

Usage

elimCloseCoord(
  dat,
  useCol = 1:2,
  elimIdentOnly = FALSE,
  refine = 2,
  nDig = 3,
  callFrom = NULL,
  silent = FALSE
)

Arguments

`dat`	matrix (or data.frame) with main numeric input
`useCol`	(numeric) index for numeric columns of 'dat' to use/consider
`elimIdentOnly`	(logical) if TRUE, eliminate real duplicated points only (ie identical values only)
`refine`	(numeric) allows increasing stringency even further (higher 'refine' .. more lines considered equal)
`nDig`	(integer) number of significant digits used for rounding, if two 'similar' values are identical after this rounding the second will be eliminated.
`callFrom`	(character) allows easier tracking of message(s) produced
`silent`	(logical) suppress messages

Value

resultant matrix/data.frame

Examples

da1 <- matrix(c(rep(0:4,5),0.01,1.1,2.04,3.07,4.5),nc=2); da1[,1] <- da1[,1]*99; head(da1)
elimCloseCoord(da1)
