Issue with bi- gram or more in Polarity table about sentimentr HOT 6 CLOSED

Please provide a reproducible example.

from sentimentr.

Hi,

require(sentimentr)
require(qdap)

Texts

mytext <- c(
"hopefully wallet will comeback",
"excelente",
"duplicate photo finder",
"Thanks Staff!",
"limit your sentence"
)

Polarity table

set.seed(10)
key <- data.frame(
words = c("excelente","limit","duplicate photo finder","wallet will comeback","thanks"),
polarity = c(1,-1,-1,-1,1),
stringsAsFactors = FALSE
)

mykey <- as_key(key)

striptext=function(x){
x=removePunctuation(stripWhitespace(tolower(x))) }

text=as.character(striptext(mytext))
text=replace_number(text)
text=replace_emoticon(text,emoticon_dt = sentimentr::emoticons)
text=replace_grade(text, grade_dt = sentimentr::grades)

Sentimentr polarity

Sentir=sentiment_by(text,mykey,valence_shifters_dt = valence_shifters_table,by=NULL,
amplifier.weight = 3, n.before = 5, n.after = 3
,question.weight = 2, but.weight = 0.85, missing_value = 0)

Qdap Polarity

QDAPoutput=counts(polarity(striptext(mytext),polarity.frame = mykey,
constrain = F,negators = qdapDictionaries::negation.words,
amplifiers = qdapDictionaries::amplification.words,
deamplifiers = qdapDictionaries::deamplification.words,
question.weight = 3, amplifier.weight = 2,
n.before = 5, n.after = 3))[, "polarity"]

Final output

outp=cbind(Sentir,QDAPoutput)

If u check the final output "outp", Sentimentr is not scoring but Qdap does.

I believe you need to name the argument to sentiment_by as the second argument to this function is not the polarity table as you assume, polarity_dt =mykey

Hi .. i changed it to Sentiment . its working .. Thanks..

But it shows this warning :

Warning message:
In [.data.table(dat[, :=(indx, wc < 1), by = c("id", "sentences", :
with=FALSE ignored, it isn't needed when using :=. See ?':=' for examples.

You need the latest version from github. A change in data.table. If you don't feel like updating the warning message can be ignored.
