Exercise 3: Exporting data to a file
To export an r-object to a file, write.table
function is used. For example, we can export the bodydata
table we just imported as a text file named bodydata-export.txt
as,
write.table(bodydata, file = "_data/bodydata-export.txt",
row.names = FALSE, quote = FALSE)
We can also use write.csv
function to export the data in csv
format. The txt
and csv
file format only holds data in tabular structures. Sometimes we need to save other R-objects such as fitted models or list for which we can use Rdata
format. We can save our bodydata
objects in Rdata
format as,
save(bodydata, file = "_data/bodydata-export.rdata")
This will export bodydata object to a file named bodydata-export.rdata
in _data
folder in your project directory.
