在R中绘制用于播放connect4的矩形板时出错

Question

我想基于我拥有的tictactoe板创建一个连接四板。然而事情听起来并不匹配，我的结果并不合适。 我想要6行7列！

par(pty="s") # square plot type
x = rep(1:6, each = 6)
y = rep(1:7, times = 7)
symbols(x, y, squares=rep(1, times=42),
        inches=FALSE, # match squares to axes
        xlim=c(0,7),
        ylim=c(8,0)) # flip y axis to match matrix format
board = matrix(rep("E", times=42), nrow=6, ncol=7)

我收到此错误：

Error in xy.coords(x, y, xlab = deparse(substitute(x)), ylab = deparse(substitute(y))) : 
  'x' and 'y' lengths differ

以下是tictactoe及其电路板的代码：

par(pty="s") # square plot type
x = rep(1:3, each = 3)
y = rep(1:3, times = 3)
symbols(x, y, squares=rep(1, times=9),
        inches=FALSE, # match squares to axes
        xlim=c(0,4),
        ylim=c(4,0)) # flip y axis to match matrix format
board = matrix(rep("E", times=9), nrow=3, ncol=3)

将第2行和第3行更改为以下内容后：

x = rep(1:6, each = 7); y = rep(1:7, times = 6)

我得到了以下情节。你知道为什么水平线是这样的吗？并不尖锐，他们是模糊的？

Answer 1

par(pty="s") # square plot type
x = rep(1:7, each = 6)
y = rep(1:6, times = 7)
symbols(x, y, squares = rep(1, times=42),
        inches=FALSE, # match squares to axes
        xlim=c(0,8),
        ylim=c(8,0),
        axes = FALSE,
        xlab = '', ylab = '') # flip y axis to match matrix format
board = matrix(rep("E", times=42), nrow = 6, ncol = 7)

如果您愿意，可以重新添加轴，刻度和标签
