Suppose I have two columns of entries, how can I get the union of the
two columns? Please note: I input my columns through excel. These
entries have text format in excel. Also, out of curiosity, how can I
find out the data type of a data frame ?
> a <- read.csv("book1.csv")
1 apple soda
2 orange apple
3 soda green
4 red yellow
5 white blue
 2 3 5 4 6 1
I want the actual names instead of the indexes.
