I have made a dataframe based on a set of twitters in the following form:
rdmTweets <- userTimeline("rdatamining", n=200)
df <- do.call("rbind", lapply(rdmTweets, as.data.frame))
Now I am saving the data frame with save in this way:
save(df, file="data")
How I can load that saved data frame for future use? When I use:
df2 <- load("data")
and I apply dim(df2) it should return the quantity of tweets that data frame has, but it only shows 1.

As @mrdwab points out, save saves the names as well as the data/structure (and in fact can save a number of different R objects in a single file). There is another pair of storage functions that behave more as you expect. Try this:
saveRDS(df, file="mytweets.rds")
df2 <- readRDS("mytweets.rds")
These functions can only handle a single object at a time.
