Get all.polarity value from qdap package results in R - r

Question

I wanted to do sentimental analysis in R using qdap package.
It gives out a data frame containing all.all, all.wc, all.polarity, all.pos.words, all.neg.words etc.
I want to extract the values of all.polarity, all.pos.words,all.neg.words but when i use
sentiment$all.polarity or sentiment$all.pos.words,
I get NULL in result.
dput(head(sentiment))
list(structure(list(all = c("all", "all", "all"), wc = c(44L,
1L, 1L), polarity = c(-0.422115882408869, 0, 0), pos.words = list(
"-", "-", "-"), neg.words = list(c("disappointed", "issue"
), "-", "-"), text.var = c("list(list(content = \" misleaded icici bank customer care branch excutive really disappointed bank dont know steps take get issue fixed\", meta = list(author = character(0), datetimestamp = list(sec = 20.097678899765, min = 51, hour = 11, mday = 6, mon = 6, year = 115, wday = 1, yday = 186, isdst = 0), description = character(0), heading = character(0), id = \"1\", language = \"en\", origin = character(0))))",

Can anyone suggest how to do this?

Answer 1

The following works for me -
library(qdap)
text <- "I am liking the work " # the text for which polarity score is needed
sentiment <- polarity(text) #make the call
sentiment$all$pos.words # returns the positive words detected by the algo
#[[1]]
#[1] "liking" "work"
sentiment$all$polarity # returns the sentence polarity score
#[1] 0.8944272
