Question

I’m using twitteR packages (and all needed packages), which are all latest version to do “Lynas Malaysia” twitter sentiment analysis.

The source code is as below:

library(twitteR)
library(plotrix)

dontshowtweet <- 0
showtweetyesterday <- searchTwitter("lynas", n=1000, 
                                    date=as.character(Sys.Date()-7))
sources <- sapply(showtweetyesterday, function(x) x$getScreenName())
sources <- gsub("</a>", "", sources)
sources <- strsplit(sources, ">")
sources <- sapply(sources, function(x) ifelse(length(x) > 1, x[2], x[1]))

pie(table(sources),
    main = "Who is tweeting about me")
length(showtweetyesterday)

df <- twListToDF(showtweetyesterday)
df[1:1000,c(10,4)] #screen name & created date
length(showtweetyesterday)

I still faced error, caused by RCurl. By using warnings(), I got:

In mapCurlOptNames(names(.els), asNames = TRUE) :
Unrecognized CURL options: date

How to solve this error?

Thanks.

According to the manual, the searchTwitter function has no date argument: you probably want since instead.
