Pick values from mapping data

Pick values from mapping data based on coordinates of x and y.

pick(
  .df,
  x = NULL,
  y = NULL,
  phase = if (is.null(x)) NULL else paste0("P", seq_along(x)),
  i = data.frame(x, y, phase),
  ...
)

Arguments

.df	Mapping data. Currentl version only supports `qm_xmap` object.
x, y	Integer vectors specifying x- and y-coordinates of pixels of mapping data. In other words, x- and y- corresponds to n-th column and row of a matrix.
phase	Name of phases comprising the pixels to be picked. If not manually supplied `phase` is supplied by `c('P1', 'P2', ...)`.
i	A data frame with clumns `x`, `y`, and `phase`. `i` have priority to `x`, `y`, and `phase`.`
...	Ignored
