I am using the following R script to write the data. table into the excel file in my set directory. However, the size of the file is in GB's as the total rows are 50 million+. Hence upon opening the file, I just see a blank grey screen and nothing else.
How can I see the contents in the file?
The first line is just for illustration purpose.
Final1 <- rep(iris, times = 1000000) fwrite(Final1,"data2.csv") 
You mention that this is part of the report. I would be willing to bet good money that whoever will be reading this report will not check all or most of the values by hand. In which case, you don't need a format that is easily browsable, e.g. xlsx or even csv. If this indeed is the case, you might want to try a (relational) database. If you do not have anything centralized, you might want to give SQLite a try. You save everything into one file which acts as a database. There are packages that handle this interaction in R. You can try with sqldf or RSQLite.
