## ggfacet - single ggplot2 plot matrix with facet_grid

### Description

ggfacet - single ggplot2 plot matrix with facet_grid

### Usage

    ggfacet(data, mapping = NULL, columnsX = 1:ncol(data),
      columnsY = 1:ncol(data), fn = ggally_points, ...,
      columnLabelsX = names(data[columnsX]),
      columnLabelsY = names(data[columnsY]), xlab = NULL, ylab = NULL,
      title = NULL, scales = "free")

### Arguments

`data` | data.frame that contains all columns to be displayed. This data will be melted before being passed into the function `fn`
`mapping` | aesthetic mapping (besides `x` and `y`). See `aes()`
`columnsX` | columns to be displayed in the plot matrix
`columnsY` | rows to be displayed in the plot matrix
`fn` | function to be executed. Similar to `ggpairs` and `ggduo`, the function may either be a string identifier or a real function that `wrap` understands.
`...` | extra arguments passed directly to `fn`
`columnLabelsX, columnLabelsY` | column and row labels to display in the plot matrix
`xlab, ylab, title` | plot matrix labels
`scales` | parameter supplied to `ggplot2::facet_grid`. Default behavior is `"free"`

### Examples

    # Small function to display plots only if it's interactive
    p_ <- GGally::print_if_interactive
    library(chemometrics)
    data(NIR)
    NIR_sub <- data.frame(NIR$yGlcEtOH, NIR$xNIR[,1:3])
    str(NIR_sub)
    x_cols <- c("X1115.0", "X1120.0", "X1125.0")
    y_cols <- c("Glucose", "Ethanol")

    # using ggduo directly
    p <- ggduo(NIR_sub, x_cols, y_cols, types = list(continuous = "points"))
    p_(p)

    # using ggfacet
    p <- ggfacet(NIR_sub, x_cols, y_cols)
    p_(p)

    # add a smoother
    p <- ggfacet(NIR_sub, x_cols, y_cols, fn = 'smooth_loess')
    p_(p)
    # same output
    p <- ggfacet(NIR_sub, x_cols, y_cols, fn = ggally_smooth_loess)
    p_(p)

    # Change scales to be the same in for every row and for every column
    p <- ggfacet(NIR_sub, x_cols, y_cols, scales = "fixed")
    p_(p)
