这个错误是什么意思"使用tabplot包时if(any(B <1))停止("B太小")的错误"

Question

我找到了tabplot包,可视化大数据库.我使用下面的代码运行它,但我在不同的数据帧上得到此错误:

"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"

这是一个例子:

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？

根据schuemie的评论，此错误与 所需的内存量有关ffdfdlpy，并且可以通过每个会话运行来修复

options(ffmaxbytes = min(getOption("ffmaxbytes"),.Machine$integer.max * 12))

将允许这个工作。

我可以确认这适用于sessionInfo()：
