我是R编程或Twitter API的新手。
当我运行以下代码时:
#https://cran.r-project.org/web/packages/rtweet/index.html
#http://127.0.0.1:1410
#Twitter Data Analysis
twitter_packages <- c("rtweet","httpuv")
### checking if packages are already installed and installing if not
check.install.load.Package<-function(package_name){
if(!package_name%in%installed.packages()){
install.packages(package_name)
}
library(package_name,character.only = TRUE)
}
for(package in twitter_packages){
check.install.load.Package(package)
}
## whatever name you assigned to your created app
#appname <- "Tech Dope"
appname <- "RTestApplicationSub"
## api key (example below is not a real key)
#key <- "XXXXXXXXXXXXX"
key <- "XXXXXXXXXXXXX"
## api secret (example below is not a real key)
#secret <- "XXXXXXXXXXXXX"
secret <- "XXXXXXXXXXXXX"
## create token named "twitter_token"
twitter_token <- create_token(
app = appname,
consumer_key = key,
consumer_secret = secret)
india_india <- get_trends("India")
for(india in as.vector(india_india$trend)){
gc()
## create token named "twitter_token"
# twitter_token <- create_token(
# app = appname,
# consumer_key = key,
# consumer_secret = secret)
fetchedTweets=search_tweets(india,10000,include_rts = FALSE,type = "mixed")
write.csv(fetchedTweets,paste0("C:\\Users\\Subhrajit\\Documents\\R Scripts\\MY_DATA_SETS\\TEST_DATA_TWITTER\\",india,".csv"), row.names = FALSE)
}
fetchedTweets=search_tweets("rohingya india",10000,include_rts = FALSE,type = "mixed")
write.csv(fetchedTweets,paste0("C:\\Users\\Subhrajit\\Documents\\R Scripts\\MY_DATA_SETS\\TEST_DATA_TWITTER\\rohingya.csv"), row.names = FALSE)
class(fetchedTweets)
#write.csv(fetchedTweets,"C:\\Users\\Subhrajit\\Documents\\R Scripts\\MY_DATA_SETS\\TEST_DATA_TWITTER\\Aadhar.csv")
我收到此错误:
Searching for tweets...
Finished collecting tweets!
Searching for tweets...
Finished collecting tweets!
Searching for tweets...

Searching for tweets...

Error in x[[1]] : subscript out of bounds
In addition: Warning messages:

2: rate limit exceeded.
现在根据twitter API文档,API调用仅限于 请求/ 15分钟窗口(用户身份验证)180 请求/ 15分钟窗口(app auth)450
但在我的情况下,我已超过&#34;超出限额&#34;在search_tweets()被调用6次之后。
我可以通过将循环重写为:
来避免错误i=1;
for(india in as.vector(india_india$trend)){
gc()
i<-i+1
if(i%%5==0){
Sys.sleep(600)
}
## create token named "twitter_token"
# twitter_token <- create_token(
# app = appname,
# consumer_key = key,
# consumer_secret = secret)
fetchedTweets=search_tweets(india,10000,include_rts = FALSE,type = "mixed")
write.csv(fetchedTweets,paste0("C:\\Users\\Subhrajit\\Documents\\R Scripts\\MY_DATA_SETS\\TEST_DATA_TWITTER\\",india,".csv"), row.names = FALSE)
}
我的问题如下: 1)每次search_tweets()调用是否会调用多少次API调用? 2)是否取决于提取的推文数量?
