I am working in R with the twitteR package, which is meant to get information from Twitter through their API. After getting authentificated, I can download information about any user with the getUser function. However, I am not able to do so with usernames which are only numbers (for example, 1234). With the line getUser("1234") I get the following error message:
Error in twInterfaceObj$doAPICall(paste("users", "show", sep = "/"),
params = params, : Not Found (HTTP 404).
Is there any way to get user information when the username is made completely of numbers? The function tries to search by ID instead of screenname when it finds only numbers.
Thanks in advance!
First of all, twitteR is deprecated in favour of rtweet, so you might want to look into that.
The specific user ID you've provided is a protected account, so unless your account follows it / has access to it, you will not be able to query it anyway.
Using rtweet and some random attempts to find a valid numerical user ID, I succeeded with this:
library(rtweet)
users <- c("989", "andypiper")
usr_df <- lookup_users(users)
usr_df
rtweet also has some useful coercion functions to force the use of screenname or ID (as_screenname and as_userid respectively)

I need to extract Twitter data, specific to a country using the place_country: keyword in the search_fullarchive command.
x<-search_fullarchive("keyword", n=100,fromDate ="202003151558", toDate="202004101900",env_name="name",parse=TRUE,token = Token, place_country:"US")
After execution, I get the error:
"object 'place_country' not found."
search_fullarchive() sends requests to the premium Twitter API which uses other operators than the free API.
You have to use the place: operator in the search query instead.
Type ?search_fullarchive to see the limited documentation on this.
Or look at a few imperfect examples here:
How to define search queries in rtweet fullarchive and 30day search
Have you figure this out? If not, I had the same issue and I can help.
Your operator place_country:US should be in the keyword search argument x <- search_fullarchive(q = "place_country:US", n=100,fromDate ="202003151558", toDate="202004101900",env_name="name",parse=TRUE,token = Token)
Cheers!
I try to download the reports available in Salesforce via the URL, e.g.
http://YOURInstance.my.salesforce.com/012389u13541?export=1&enc=UTF-8&xf=csv
in R.
I already did some investigation to access the report via HTTR-GET, however, up until today without any meaningful outcomes. Unfortunately, R is downloading HTML-code instead of the desired csv file. I also tried to realize the approach suggested here:
https://salesforce.stackexchange.com/questions/47414/download-a-report-using-python
The package "RForcecom" allows the interaction via an API, but I was not able to figure out how to realize above solution in R.
General GET-Request:
GET("http://YOUR_Instance.my.salesforce.com/012389u13541?export=1&enc=UTF-8&xf=csv")
I expect the output to be in csv format, but I receive the report data as html source code.

Did anyone of you guys encounter same issues and can provide guidance? Any kind of help is much appreciated. Thanks in advance!
UPDATED and not-working R-Snippet:
library(RForcecom)
library(httr)
username='username'
password='password'
instanceURL <- "https://login.salesforce.com/"
session <- rforcecom.login(username, password, instanceURL)
sid=as.character(session['sessionID'])
url='http://YOURInstance.my.salesforce.com/012389u13541?export=1&enc=UTF-8&xf=csv'
getData=GET(url,add_headers('Content-Type'='application/json','Authorization'=paste0("Bearer ",sid),'X-PrettyPrint'='1'),set_cookies('sid'=sid))
Are you sure you have a valid report id? It doesn't look right (did you just obfuscate it for purposes of this post?). What is in that HTML you're getting, an error message? SF login screen?
What you're doing is effectively "screen scraping". This is not a real API, it can break at any time, you should find/build something that properly uses Salesforce Analytics API. You've been warned.
But if you're after a quick and dirty solution...
You need to pretend you're an authenticated user, that you have a valid session id. Add a cookie to your GET request.
How to get a valid session id?
You'd have to log in to SF first (for example use SOAP API's login call or I listed some REST api ideas here: https://stackoverflow.com/a/56034159/313628 )
or display some user's session ID in a SF formula, visualforce page and user would copy-paste it to your app.
Once you have it - add a Cookie header to your GET with value sid=<session id goes here>
Here's a raw request & response in SoapUI.
I recently struggled with the same issue, there's a magic parameter you need to add to the query : isdtp=p1
so if you try:
http://YOURInstance.my.salesforce.com/012389u13541?export=1&enc=UTF-8&xf=csv&isdtp=p1
it should return you the file directly.
In your example, I don't think that you can use the rforcecom session with httr functions as you are trying.
Here is a slightly different way to solve the problem.
Rather than trying to retrieve a report that you already created in Salesforce, why not specify the report in SOQL and use rforcecom.query function to execute the SOQL from r. That would return the data in a data frame and would require no further data wrangling in r to make it useable.
I use this technique often and once you get used to the Salesforce API I think that its probably faster and more powerful for most use cases.
Here is a simple function that I use to return select opportunity data for all opportunities in Salesforce.
getSFOpps <- function(session) {
#Construct SOQL Query
soql <- "SELECT Id,
Name,
AccountId,
Amount,
CurrencyIsoCode,
convertCurrency(Amount) usd_amount,
CloseDate,
CreatedDate,
Region__c,
IsClosed,
IsWon,
LastActivityDate,
LeadSource,
OwnerId,
Probability,
StageName,
Type,
IsDeleted
FROM Opportunity"
#Retrieve Opp information
as_tibble(RForcecom::rforcecom.query(session, soql))
}
It requires that you pass in a valid session from Rforcecom.login but you seem to have that part working from your code above.
I hope this helps ...
As of v0.2.0, the {salesforcer} R package implements the Salesforce Reports and Dashboards REST API. You can execute and manage reports without needing to write functions from scratch to pull down report data. Below is an example of how to find a report in your Org and then retrieve its data. You can also just use the report Id which appears in the URL bar when viewing the report in Salesforce (highlighted in red in the screenshot below).
# install.packages('salesforcer')
library(dplyr, warn.conflicts = FALSE)
library(salesforcer)
# Authenticate using username, password, and security token ...
sf_auth(username = "test#gmail.com",
password = "{PASSWORD_HERE}",
security_token = "{SECURITY_TOKEN_HERE}")
# ... or using OAuth 2.0 authentication
sf_auth()
# find a report in your org and run it
all_reports <- sf_query("SELECT Id, Name FROM Report")
this_report_id <- all_reports$Id[1]
results <- sf_run_report(this_report_id)
results
I am using R and I need to retrieve the few most recent posts from a Twitter user (#ExpressNewsPK) using twitteR api. I have created an account and have an access token, etc. I have used the following command to extract the tweets:
setup_twitter_oauth(consumerkey,consumersecret,accesstoken,accesssecret)
express_news_tweets <- searchTwitter("#ExpressNewsPK", n = 10, lang = "en" )
However, the posts that are returned aren't the most recent ones from this user. Where have I made a mistake?
I think searchTwitter would search with the search string provided (here #ExpressNewsPK). So instead of giving tweets by #ExpressNewsPK it would give tweets which are directed to #ExpressNewsPK.
To get tweets from #ExpressNewsPK, you have a function named userTimeline which would give tweets from a particular user.
So after you are done with setup_twitter_oauth, you can try
userTimeline("ExpressNewsPK")
read more about it at ?userTimeline
When you use searchTwitter(), you call the Twitter Search API. Search API only returns a sample history of the tweets.
What you really need to do is to call Twitter Streaming API. Using it you'll be able to download tweets in near real time. You can read more about the Streaming API here: https://dev.twitter.com/streaming/overview
This question has been asked many times for php, C# and some other programming languages. I don't find any information for R though and I can't derive a solution from the other topics.
I try to do facebook data mining in R with the package Rfacebook:
library(devtools)
install_github("pablobarbera/Rfacebook/Rfacebook")
require("Rfacebook")
fb_oauth <- fbOAuth(app_id="ID", app_secret="SECRET",extended_permissions = TRUE)
After authenticating, facebook already gives me an error (though I'm not sure, if it has anything to do with the problem):
For starters, I'd like to access my own profile now:
myProfile <- getUsers("me",token=fb_oauth)
and that's when the console display the following error:
An active access token must be used to query information about the current user.
How can I fix this?
I am using RFacebook package to do data mining.
For example, to get the facebook page then we do
fb_page <- getPage(page="facebook", token=fb_oauth)
In my case is it is a private group and the URL is something like this. So how do I get the page info for a group? I tried the following but got the following error.
Error in callAPI(url = url, token = token) : Unknown path
components: /posts
my_page <- getPage(page="group/222568978569", token=my_oauth)
This isn´t a reproducible example because the page you mention doesn´t exist. But I suggest that you check that this group has authorized your app. Note that after the introduction of version 2.0 of the Graph API, only friends/groups who are using the application that you used to generate the token to query the API will be returned.
