R: How to save lists into csv?

Question

So im actually working on twitteR and i need a way to store my tweets into a csv file and pull it out when i need it . This is due to the idea i want to compile the tweets i collect and then apply them to my algorithms to do the calculations later. So , i thought of trying

            write.csv(tweets, file = "newfile", row.names = TRUE, sep = ',', col.names = TRUE)

which only works if create a data frame tho :/ . The tweets that i collect looks like this

 [[1]]
 [1] "anonymous: boring!"

 [[2]]
 [1] "anonymous: random message !"

.... ......

Any ideas?

Edited: my str(tweets) this is just 3 tweets i just pulled out

Answer 1

Not tested, but from what I've read online, it seems like the following should work:

1. Convert the list to a data.frame

   library(plyr) 
   tweets.df = ldply(tweets, function(t) t$toDataFrame())
   

2. Use write.csv as before, but just on the tweets.df object instead of the tweets object.

   write.csv(tweets.df, file = "newfile.csv")

Answer 2

You can use the following to convert tweets into tweets dataframe:

tweets.df <- do.call("rbind", lapply(tweets, as.data.frame)) 

Then use tweets.df in your write.csv function.

Answer 3

using twitteR package:

convert your tweets to data frame

tweets2df <- twListToDF(tweets)

then save it to csv

write.csv(tweets2df, file = "tweets.csv")
