What is the meaning of this error "Error in if (any(B < 1)) stop("B too small")" while using tabplot package

I found the tabplot package for visualizin a large data base. I ran it using the code below but I get this error on different data frames:

"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"

Here is an example:

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)

Any Idea how to overcome this issue?

UPDATE - I used another computer and it works fine.Both computers are on Windows 64-bit but on the computer that I got it to work the OS is Win7 pro and on the computer that has the error the OS is WIN SERVER 2013

Solution

  • According to a comment by schuemie, this error has to do with the amount of memory needed by ffdfdlpy, and can be fixed with a per-session run of

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

    will allow this to work.

    I can confirm this works with sessionInfo():
