描述----------Description----------
Visualizes compositional, 3-dimensional data in an equilateral triangle.
可视化的成分，3维的数据，在一个等边三角形。
用法----------Usage----------
ternaryplot(x, scale = 1, dimnames = NULL,
dimnames_position = c("corner","edge","none"),
dimnames_color = "black", id = NULL, id_color = "black",
id_just = c("center", "center"),
coordinates = FALSE, grid = TRUE, grid_color = "gray",
labels = c("inside", "outside", "none"),
labels_color = "darkgray", border = "black", bg = "white",
pch = 19, cex = 1, prop_size = FALSE, col = "red",
main = "ternary plot", newpage = TRUE, pop = TRUE, ...)
参数----------Arguments----------
参数：x
a matrix with three columns.
矩阵有三列。
参数：scale
row sums scale to be used.
行求和规模要使用。
参数：dimnames
dimension labels (defaults to the column names of x).
标注标签（默认为列名的x）。
参数：dimnames_position, dimnames_color
position and color of dimension labels.
维标签的位置和颜色。
参数：id
optional labels to be plotted below the plot symbols. coordinates and id are mutual exclusive.
可选的标签，被绘制在图形的下方符号。 coordinates和id是互斥的。
参数：id_color
color of these labels.
这些标签的颜色。
参数：id_just
character vector of length 1 or 2 indicating the justification of these labels.
字符向量长度为1或2表示这些标签的理由。
参数：coordinates
if TRUE, the coordinates of the points are plotted below them. coordinates and id are mutual exclusive.
如果TRUE，点的坐标绘制它们下面。 coordinates和id是互斥的。
参数：grid
if TRUE, a grid is plotted. May optionally be a string indicating the line type (default: "dotted").
如果TRUE，一个网格绘制。可能选择一个字符串，指示线路类型（默认："dotted"）。
参数：grid_color
grid color.
网格颜色。
参数：labels, labels_color
position and color of the grid labels.
网格标签的位置和颜色。
参数：border
color of the triangle border.
颜色三角形的边界。
参数：bg
triangle background.
三角形的背景。
参数：pch
plotting character. Defaults to filled dots.
绘制字符。默认为填充点。
参数：cex
a numerical value giving the amount by which plotting text and symbols should be scaled relative to the default. Ignored for the symbol size if prop_size is not FALSE.
一个数值，绘制文字和符号应扩大相对于默认。 prop_size忽略符号的大小，如果FALSE。
参数：prop_size
if TRUE, the symbol size is plotted proportional to the row sum of the three variables, i.e., represents the weight of the observation.
如果TRUE，符号的大小绘制三个变量的行总和成比例，即，表示观察的重量。
参数：col
plotting color.
绘制的颜色。
参数：main
main title.
主标题。
参数：newpage
if TRUE, the plot will appear on a new graphics page.
如果TRUE，图上会出现一个新的图形页面。
参数：pop
logical; if TRUE, all newly generated viewports are popped after plotting.
逻辑TRUE如果，所有新生成的视口被弹出后绘制。
参数：...
additional graphics parameters (see par)
额外的图形参数（见par）
Details
详细信息----------Details----------
A points' coordinates are found by computing the gravity center of mass points using the data entries as weights. Thus, the coordinates of a point P(a,b,c), a + b + c = 1, are: P(b + c/2, c * sqrt(3)/2).
A点的坐标被发现通过计算质点的重心作为权重，使用的数据条目。因此，一个点的坐标P(a,b,c)，a + b + c = 1，是：P(b + c/2, c * sqrt(3)/2)。
