Controlling widths in write.fwf()

Thanks Brendan. 
write.table() doesn't seem to do it for me. The problem is that my data
is not formatted as well as you show in the example. There are numbers
and strings of varying sizes and write.table() misses the format.

Hi Aparna, you could always use the write.table function and set  
sep="". This will put all of your data into a sort of "fixed-width"  
column depending on what you specify to separate the values. See basic  
example below:

x<-matrix(nrow=2, ncol=2, c(1,2,3,4))
write.table(x, "/Users/morse07/Desktop/x.txt", sep="",  
col.names=FALSE, row.names=FALSE)

Note that any spaces you insert between the "" after the sep command  
will insert 1 fixed-width column per space in your file.

Hope that helps,
Brendan

Is there a way to handle the widths of values being written to a file
using wrtite.fwf() ?

For example, I used read.fwf(file, width.vector) to read a file. After
making the necessary data manipulation, I want to write the data to a
new file in the same width.vector format. Is there a way to specify
this?

Thanks in Advance
Aparna
