r - 绘制矩形板以在 R 中播放 connect4 时出错

Question

我想根据我拥有的 tictactoe 板创建一个连接四板。然而，事情听起来不匹配，我没有完全正确的结果。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)

我收到这个错误：

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

下面是 tictactoe 的代码和之后显示的板子：

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？并且不锐利并且它们模糊？

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，您可以重新添加轴、刻度和标签
