## A wrapper for function gplot - Two-Dimensional Visualization of Graphs

### Description

The function calls function `gplot` from the library `sna` with different defaults. Use fun for plotting image graphs.

### Usage

    gplot1(M, diag = TRUE,
        displaylabels = TRUE, boxed.labels = FALSE,
        loop.cex = 4, edge.lwd = 1, edge.col = "default",
        rel.thresh = 0.05, ...)

    gplot2(M, uselen = TRUE, usecurve = TRUE,
        edge.len = 0.001, diag = TRUE,
        displaylabels = TRUE, boxed.labels = FALSE,
        loop.cex = 4, arrowhead.cex = 2.5,
        edge.lwd = 1, edge.col = "default", rel.thresh = 0.05, ...)

### Arguments

`M` | A matrix (array) of a graph or set thereof. This data may be valued.
`diag` | Boolean indicating whether or not the diagonal should be treated as valid data. Set this `TRUE` if and only if the data can contain loops. `diag` is `FALSE` by default.
`rel.thresh` | Real number indicating the lower relative (compared to the highest value) threshold for tie values. Only ties of value `thresh` are displayed. By default, `thresh = 0`.
`displaylabels` | Boolean; should vertex labels be displayed.
`boxed.labels` | Boolean; place vertex labels within boxes.
`arrowhead.cex` | An expansion factor for edge arrowheads.
`loop.cex` | expansion factor for loops; may be given as a vector, if loops are to be of different sizes.
`edge.col` | Color for edges; may be given as a vector or adjacency matrix, if edges are to be of different colors.
`edge.lwd` | Line width scale for edges; if set greater than 0, edge widths are scaled by `edge.lwd*dat`. May be given as a vector or adjacency matrix, if edges are to have different line widths.
`edge.len` | if `uselen == TRUE`, curved edge lengths are scaled by `edge.len`.
`uselen` | Boolean; should we use `edge.len` to rescale edge lengths.
`usecurve` | Boolean; should we use `edge.curve`.
`...` | Additional arguments to `plot` or `gplot` from package `sna`: `mode`: the vertex placement algorithm; this must correspond to a `gplot.layout` function from package `sna`.

### Value

Plots a graph.
