## generic for smoothScatter

### Description

smoothScatter method for PCA class

### Usage

    smoothScatter(
      x,
      y = NULL,
      nbin = 128,
      bandwidth,
      colramp = colorRampPalette(c("white", blues9)),
      nrpoints = 100,
      ret.selection = FALSE,
      pch = ".",
      cex = 1,
      col = "black",
      transformation = function(x) x^0.25,
      postPlotHook = box,
      xlab = NULL,
      ylab = NULL,
      xlim,
      ylim,
      xaxs = par("xaxs"),
      yaxs = par("yaxs"),
      ...
    )

    ## S4 method for signature 'PCA'
    smoothScatter(
      x,
      y = NULL,
      nbin = 128,
      bandwidth,
      colramp = colorRampPalette(c("white", blues9)),
      nrpoints = 100,
      ret.selection = FALSE,
      pch = ".",
      cex = 1,
      col = "black",
      transformation = function(x) x^0.25,
      postPlotHook = box,
      xlab = NULL,
      ylab = NULL,
      xlim,
      ylim,
      xaxs = par("xaxs"),
      yaxs = par("yaxs"),
      ...,
      comps = c(1, 2),
      pcType = "pcaScores",
      label = FALSE,
      labelThreshold = 1
    )
