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")

> sessionInfo()

Any advice on this will be much appreciated.
