Find which sector a stock belongs to - r

Given stocks in S&P500, how can I find which sector each stock belongs to, e.g. financial, energy ...., using R package, or other sources?

The term "sector" is, by itself, an ambiguous term. What one data provider calls "consumer services" may be called "restaurants" by another. That said, TTR provides a function called stockSymbols that returns some information including Sector, from NASDAQ, for ~6400 NMS stocks.
library(TTR)
ss <- stockSymbols()

If you just want stocks that are in the S&P 500, you can cheat and use the holdings of SPY (or there are tons of places that you can find the holdings of the S&P 500, including the Standard & Poors website)

Couldn't get tq_exchange() or stockSymbols() to work

I am trying to get stock symbols with these functions (both failed)
TTR::stockSymbols("AMEX")
Error in symbols[, sort.by] : incorrect number of dimensions
tidyquant::tq_exchange("AMEX")
Getting data...
Error: Can't rename columns that don't exist.
x Column Symbol doesn't exist.
Do these functions work for you? What fixes do you know to correct them? Thank you!
I get the same error. It seems like there has been some changes in the website from which these packages get the information. There is an open issue about this.
In the same thread it is mentioned that you can get the information from the underlying JSON which returns this information.

Python Mechanical soup - webscraping - Unable to open pagination link in .aspx form, even after modifying '__EVENTTARGET' and '__EVENTARGUMENT'

Can someone help me in providing the instructions on how to open the pagination link in aspx form using mechanicalsoup , I updated the __EVENTTARGET and __EVENTARGUMENT , but still it is opening the current page , instead of opening up the next page.
form = browser.select_form('#form1')

How do I control the number of elements in a nested list?

I have a function to loop through weblinks and extract the relevant tables.
List.Of.Tabs <- map(pages2, ~ {
name <- .x[1]
link <- .x[2]
Sys.sleep(2)
webpage <- read_html(link)
tbls <- html_nodes(webpage, "table")
tbls_ls <- html_table(tbls, fill = TRUE)
pos1 <- possibly(function(tbls) bind_rows(tbls) %>%
filter_all(any_vars(. %in% c("Singapore", "SGP"))) %>%
mutate(name = name)
, otherwise = NA)
pos1(tbls_ls)
})
However, on some occassion, I got this message:
Error in matrix(NA_character_, nrow = n, ncol = maxp) :
invalid 'ncol' value (too large or NA)
In addition: Warning messages:
1: In max(p) : no non-missing arguments to max; returning -Inf
2: In matrix(NA_character_, nrow = n, ncol = maxp) :
NAs introduced by coercion to integer range
I figured it was due to some lists in pages2 having more than 2 elements.
print(pages2)

How can I amend my code such that the error doesn't appear?
I cannot replicate the error messages with the provided links. But I can revise your code. You have lists with a company name and URL(s). Since you are specifying link <- .x[2], you use the first URL in each list. If you arrange a data frame, you can overcome this issue. I created a data frame based on the list object you provided. One column has company names, and the other contains URLs. map2_df() uses a company name and an URL in each row and scrape the tables. In this way, you can make sure that you access to all URLs you have.

Given your comment, I think the following would work. Please note that I do not have your real data. So this idea may/may not work. This is the best I can do.
map2_dfr(.x = mytemp$url,
.y = mytemp$company,
.f = function(x, y){read_html(x) %>%
html_nodes("table") %>%
html_table(fill = TRUE) %>%
map(.f = ~mutate_all(., .funs = list(~as.character(.)))) %>%
bind_rows() %>%
mutate(name = y)}) %>%
filter_all(any_vars(. %in% c("Singapore", "SGP")))

Quarter over Quarter in r

I have been trying to calculate the quarter over quarter change in shares with no luck. I have a data.table with approx 15millions rows.
What I need to calculate is the change in absolute values quarter by quarter according to the Holder and the stock they own.
My data table looks like this:
stock Holder Quarter Shares
1: GOOGLE Advance Capital Management, Inc. 2015 Q3 5800
2: GOOGLE Advance Capital Management, Inc. 2015 Q4 9000
3: GOOGLE Advance Capital Management, Inc. 2016 Q1 7000
4: GOOGLE Advance Capital Management, Inc. 2016 Q2 7560
5: GOOGLE Advest, Inc. 2015 Q3 12000
6: GOOGLE Advest, Inc. 2015 Q3 13450
I'm trying to use data.table functions, using
df[, qoq := c(NA, diff(Shares)), by = "Holder,stock,Quarter"]
However, I get only NA.
I was expecting something like this:
stock Holder Quarter Shares qoq
1: GOOGLE Advance Capital Management, Inc. 2015 Q3 5800 NA
2: GOOGLE Advance Capital Management, Inc. 2015 Q4 9000 4000
3: GOOGLE Advance Capital Management, Inc. 2016 Q1 7000 -2000
4: GOOGLE Advance Capital Management, Inc. 2016 Q2 7560 560
5: GOOGLE Advest, Inc. 2015 Q3 12000 NA
6: GOOGLE Advest, Inc. 2015 Q3 13450 1450
After that, I need to calculate the variance of this result, again, by Holder and stock. Is there any general function to calculate statistics by grouping several columns? I tried aggregate but is taking yearsssss...
aggregate(REPORTED_HOLDING~Quarter+FILER_NAME+STOCK_NAME, FUN=sum, data=df)
With dplyr, assuming df is you data.frame:
df %>%
group_by(stock, Holder) %>%
mutate(qoq = Shares - lag(Shares)) %>%
summarise(qvar = var(qoq, na.rm = T))

Programmatically look up a ticker symbol in R

I have a field of data containing company names, such as
company <- c("Microsoft", "Apple", "Cloudera", "Ford")
> company
Company
1 Microsoft
2 Apple
3 Cloudera
4 Ford
and so on.
The package tm.plugin.webmining allows you to query data from Yahoo! Finance based on ticker symbols:
require(tm.plugin.webmining)
results <- WebCorpus(YahooFinanceSource("MSFT"))
I'm missing the in-between step. How can I query ticket symbols programmatically based on company names?
I couldn't manage to do this with the tm.plugin.webmining package, but I came up with a rough solution - pulling & parsing data from this web file: ftp://ftp.nasdaqtrader.com/SymbolDirectory/nasdaqlisted.txt. I say rough because for some reason my calls with httr::content(httr::GET(...)) don't work every time - I think it has to do with the type of web address (ftp://) but I don't do that much web scraping so I can't really explain this. It seemed to work better on my Linux than my Mac, but that could be irrelevant. Regardless, here's what I got: Thanks to #thelatemail's comment, this seems to be working much smoother:
library(quantmod) ## optional
symbolData <- read.csv(
"ftp://ftp.nasdaqtrader.com/SymbolDirectory/nasdaqlisted.txt",
sep="|")
##
> head(symbolData,10)

10 ABAC Aoxin Tianli Group, Inc. - Common Shares S N N 100
Edit:
As per #GSee's suggestion, a (presumably) more robust way to obtain the source data is with the stockSymbols() function in the package TTR:
> symbolData2 <- stockSymbols(exchange="NASDAQ")
Fetching NASDAQ symbols...
> ##

I don't know if you just wanted to get ticker symbols from names, but if you are also looking for actual share price information you could do something like this:
namedStock <- function(name="Microsoft",
start=Sys.Date()-365,
end=Sys.Date()-1){
ticker <- symbolData[agrep(name,symbolData[,2]),1]
getSymbols(
Symbols=ticker,
src="yahoo",
env=.GlobalEnv,
from=start,to=end)
}
##
## an xts object named MSFT will be added to
## the global environment, no need to assign
## to an object
namedStock()
##
> str(MSFT)
An ‘xts’ object on 2013-09-03/2014-08-29 containing:
Data: num [1:251, 1:6] 31.8 31.4 31.1 31.3 31.2 ...
- attr(*, "dimnames")=List of 2
..$ : NULL
..$ : chr [1:6] "MSFT.Open" "MSFT.High" "MSFT.Low" "MSFT.Close" ...
Indexed by objects of class: [Date] TZ: UTC
xts Attributes:
List of 2
$ src : chr "yahoo"
$ updated: POSIXct[1:1], format: "2014-09-02 21:51:22.792"
> chartSeries(MSFT)
So like I said, this isn't the cleanest solution but hopefully it helps you out. Also note that my data source was pulling companies traded on NASDAQ (which is most major companies), but you could easily combine this with other sources.
