Add centroids manually

Add centroids manually by picking X-ray counts of selected pixels in X-ray maps.

add_centers(
  centers,
  xmap,
  x = NULL,
  y = NULL,
  phase = if (is.null(x)) NULL else paste0("P", seq_along(x)),
  i = data.frame(x, y, phase),
  ...,
  saveas = "center_add.csv"
)

Arguments

centers	c-by-p matrix returned by `find_centers()` or by manually; c clusters and p features. Used to guess initial centers (or centroids) of clusters. A value returned by , typically `data.frame` or `matrix`, indicating initial guess centers (or centroids) or clusters. See `find_centers()`.
xmap	An object generated by `read_xmap()`
x	A n-by-p training data matrix; n observations and p features. Used to train the classifier.
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	Selected ones are referenced to detect outliers. Default selects everything. Tidy selection is available. For example `c(Si, Ti)` selects them, and `c(-Si, -Ti)` selects everything except them.
i	A data frame with clumns `x`, `y`, and `phase`. `i` have priority to `x`, `y`, and `phase`.`
...	Ignored
saveas	File name to save result. `FALSE` if not saving.
