[R] Exporting data

This really depends on what your output is. As previously suggested
save() and write() are excellent suggestions.

for(ii in 1:1000){
	out <- cor( x[ii, ], y[ii, ] ) # or whatever 
	cat(ii, "\t", out, "\n", append=TRUE, file="output.txt")

This method is really not worth it for small simulations but I found
this to be extremely useful with large simulations. 

The output file can act both as log/progress report file and provide
partial results even if your program crashes. More sophisticated method
can be found under connections().

Dear All

I am a new user to R and so I have a question which I hope you can help

I am running simulations calculating correlation coefficients from
data and I was wondering whether there is a way of exporting 1000
results from R to a text file or to another file for further
manipulation. I 
am having difficulty I think because of the text combined in with the 
numerical results.

Many Thanks
