[R] Write.fwf works from Mac, throws different number of row error in Windows

[mazibuko]

Hello, 

I am having a problem with write.fwf in Windows. I wrote a code to ingest a
number of text files with weather data in them, process them, and then
output a text file with two parts: 1) a set of column names, 2) the
processed data table. 

I wrote and tested the program on my Mac, and it worked fine. However, on
the windows machine, where I intend the work to be done, when I run the
following line (last line of the script): 

> write.fwf(outframe,file=outfile1,sep="",quote=FALSE,rownames=FALSE,colnames=FALSE,
+
width=c(4,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8),append=TRUE,justify='right')

I get the following error: 

Error in data.frame(colname = colnamesMy, nlevels = 0, position = 0, width =
0,  : 
  arguments imply differing number of rows: 0, 1
In addition: Warning message:
In write.fwf(outframe, file = outfile1, sep = "", quote = FALSE,  :
  recycling 'width'

I can't see the reason for this. The data in outframe are all numeric, and
it worked on the Mac, and outframe has 7 rows on Windows and on the Mac, so
I am not sure what is going on here.

Here is my traceback() and sessionInfo() in case it helps: 

>traceback()
3: stop("arguments imply differing number of rows: ", paste(unique(nrows), 
       collapse = ", "))
2: data.frame(colname = colnamesMy, nlevels = 0, position = 0, width = 0, 
       digits = 0, exp = 0, stringsAsFactors = FALSE)
1: write.fwf(outframe, file = outfile1, sep = "", quote = FALSE, 
       rownames = FALSE, colnames = FALSE, width = c(4, 8, 8, 8, 
           8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8), append = TRUE, 
       justify = "right")

Any advice on this will be much appreciated. 

Thanks.
