Lab 4 Part 2

[mmonakho]

When running this chunk of code...

tokens <- tokens( corp, what="word", remove_punct=TRUE )

...getting this error:

Error: tokens() only works on character, corpus, list, tokens objects.

Which doesn't make sense because I checked the type of corp variable...

typeof(corp) [1] "character"

Can you post the code that declares the Corp object

I copy-pasted it at from the lab instructions: dat$mission <- tolower( dat$mission ) set.seed(1986) dat.sample <- dat[ sample( 1:50000, size=1000 ) , ] corp <- corpus( dat.sample, text_field="mission" ) corp <- ?corpus_trim(corp, what="sentences", min_token=3)

Actually, this part doesn't work either: corp <- corpus_trim(corp, what="sentences", min_token=3)

Gives this error: Error in corpus_trim(corp, what = "sentences", min_token = 3) : could not find function "corpus_trim"

make sure you have all of the packages loaded.

library( dplyr ) library( pander ) library( quanteda ) library( quanteda.textmodels ) library( quanteda.textstats ) library( quanteda.textplots )

Also the line you just linked should be:

corpustrim( corp, what="sentences", minntoken=3 )

For your first question carefully follow your corp object through the code until it gets to the tokens line. The command you posted is correct, and it should work. It looks like somewhere you either overwrote your corp object, or something went wrong with loading your packages
