ff package when reading .csv files
...v file into R. I ran the following code and am
using R version 10.1 on Windows.
>library(ff)
> read.csv.ffdf(x=NULL,"file.csv",fileEncoding="",nrows=-1,first.rows=NULL,next.rows=NULL,levels=NULL,appendLevels=TRUE,FUN="read.table",transFUN=NULL,asffdf_args=list(),BATCHBYTES=getOption("ffbatchbytes"),VERBOSE=FALSE)
Error in read.table.ffdf(FUN = "read.csv", ...) :
formal argument "FUN" matched by multiple actual arguments
Can anyone help me to fix this error. Thanks in advance.

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
I'm not really sure that it gets simpler than this example. I'm concerned
that either there's a bug in the package or that I'm missing something
completely fundamental to the function. Any thoughts? Thanks for your
time.
