r - 使用 tabplot 包时此错误 "Error in if (any(B < 1)) stop("B 太小")"的含义是什么

Question

我找到了用于可视化大型数据库的 tabplot 包。我使用下面的代码运行它，但在不同的数据帧上出现此错误:

"Error in if (any(B < 1)) stop("B too small") : 
  missing value where TRUE/FALSE needed
In addition: Warning message:
In bbatch(n, as.integer(BATCHBYTES/theobytes)) : NAs introduced by coercion"

下面是一个例子:

dat <- read.table(text = " birds    wolfs     snakes
                     3        9         7
                     3        8         4
                     1        2         8
                     1        2         3
                     1        8         3
                     6        1         2
                     6        7         1
                     6        1         5
                     5        9         7
                     3        8         7
                     4        2         7
                     1        2         3
                     7        6         3
                     6        1         1
                     6        3         9
                     6        1         1   ",header = TRUE)

任何想法如何克服这个问题？

更新 - 我使用另一台计算机，它工作正常。两台计算机都在 Windows 64 位上，但在我让它工作的计算机上，操作系统是 Win7 pro，在有错误的计算机上，操作系统是 WIN SERVER 2013

根据 schuemie 的评论，此错误与 ffdfdlpy 所需的内存量有关，并且可以通过每个 session 运行来修复
options(ffmaxbytes = min(getOption("ffmaxbytes"),.Machine$integer.max * 12))
将允许这个工作。

我可以通过 sessionInfo() 确认这有效:
