Dear R-Team,
I have a problem with writing an array to (for example) a .txt-file.
Because of the .txt-file must be read from another programm (OPL ILOG),
the syntax of the output must be from a special form:
name_of_the_object = [ [1,2, ... ],
[1,...],
This will probably do it for you. It is a function to create the output:
write.array - function(x,fileName){
outFile - file(fileName, 'w')
cat(deparse(substitute(x)), =[, sep='', file=outFile)
for (i in 1:nrow(x)){
cat('[', paste(x[i,], collapse=','), ']', file=outFile,
Try this:
write.ilog - function(X, file = ) {
w - function(x, z, file)
cat([, paste(x, collapse = ,), ], z, sep = , file = file)
if (!identical(file, )) {
file - open(file, w)
on.exit(close(file))
}
cat(X=[, file = file)
nr - nrow(X)
for(i in 1:nr)
Hi, I found that when writing a matrix with row names
and column names to an Excel file, the Excel file when
opened has column names shifted towards left resulting
disalignment. Here is an exmaple
x-matrix(1:20,nrow=4,dimnames=list(paste('r',1:4,sep=''),paste('c',1:5,sep='')))

By default there is no column name for a column of row names. If
'col.names = NA' and 'row.names = TRUE' a blank column name is
added, which is the convention for CSV files to be read by
spreadsheets.

In addition to the solutions already provided, note that if *all* you
want to do is save your dataframe in a file, and later recreate it
from that file, you can use dump().
dump('Tall',file='Tall.r')
rm(Tall) ## just to demonstrate that the next command will recreate Tall
