Just start my learning about text mining, followed the book, I used tm::inspect() to see the first information in data "crude", but unlike the example on that book, R showed me the following things instead of the detail information like the book said.
I want to know why would this happened? and how could I correct it? Thanks! (Sorry for my poor English lol..)
my code:
library(tm)
data(crude)
inspect(crude[1])
summary(crude)
and the output:
> inspect(crude[1])

Could it be that you forgot a pair of square brackets?
library(tm)
data("crude")
inspect(crude[[1]])
for me, it prints out the following:

Diamond Shamrock Corp said that
effective today it had cut its contract prices for crude oil by
1.50 dlrs a barrel.
The reduction brings its posted price for West Texas
Intermediate to 16.00 dlrs a barrel, the copany said.
"The price reduction today was made in the light of falling
oil product prices and a weak crude oil market," a company
spokeswoman said.
Diamond is the latest in a line of U.S. oil companies that
have cut its contract, or posted, prices over the last two days
citing weak oil markets.
