How to save a DataFrame in R

Question

I have made a Data Frame in R which is not so big but takes times to build, I want to save this as a file which I can load again in R?

Answer 1

Suppose your DataFrame is named as df:

write.csv(df,file="exmp.csv")

Then you can load the csv file easily:

read.csv(file="exmp.csv")

Alternate method for this is :

save(df,file="data.Rda")

Now load it by:

load("data.Rda")
