Dear R users,
I am running a R code which gives me 10 columns and
160 rows. I need to run the code for 100 times and each time I need to store
the results in a single file.
I do not know how can I store them in a single file without over writting
the results?
Thanks
Alex

You could put all of your results into a single list, then just save the list. Or, functions like write.table and write have an append argument, set that to true and the information will be appended to the file rather than overwriting it. -- Gregory (Greg) L.

Collect the results in a list (one entry for each matrix) and then 'save' the list. When you 'load' it back in, you can easily reference each element for further processing.

If you absolutely need a single file for each iteration, you can also
include the iteration number into your output filename.
for(i in 1:dim(your input data)[1]) {
results<- your calculation
write.csv(results, paste("filename", "_", i,
sep=""))
}

Dear R users,

the results in a single file.
I do not know how can I store them in a single file without over writting
