Hi Josh, Thanks for helping me with my second topic of the day. I am scraping from the fmpcloud website and trying to get data from their survivorship free data (so they say). The result is supposed to be in json format, but I can't figure out how to get any of R's json interpreters to parse t

Hi, I am scraping some data from the internet and I got what I want but in a big long string (sort of) and can't figure out a way to parse it. What I have gotten to is > mystring {xml_nodeset (1)} [1] {\n "symbol": "ABI",\n "open": 21.04,\n "high": 21.05,\n "low": 20.06,\n "close": 20.2,\

Thanks, Iris. That is what I suspected, but it wasn't clear to me from the docs. Best, Bert On Sun, Jan 5, 2025 at 10:16 AM Iris Simmons wrote: > > I would use two because it does not force the evaluation of the other > arguments in the ... list. > > > > On Sun, Jan 5, 2025, 13:00 Bert Gunter

I would use two because it does not force the evaluation of the other arguments in the ... list. On Sun, Jan 5, 2025, 13:00 Bert Gunter wrote: > Consider: > > f1 <- function(...){ > one <- list(...)[['a']] > two <- ...elt(match('a', ...names())) > c(one, two) > } > ## Here "..." is an ar

[R] Extracting specific arguments from "..."

Consider: f1 <- function(...){ one <- list(...)[['a']] two <- ...elt(match('a', ...names())) c(one, two) } ## Here "..." is an argument list with "a" somewhere in it, but in an unknown position. > f1(b=5, a = 2, c=7) [1] 2 2 Which is better for extracting a specific named argument, one<- o

I don't see atr_df appearing in my current directory. Also, I assume that the input data frame is named ohlc? Or am I missing something. Thanks, --JJS From: Joshua Ulrich Sent: Sunday, January 5, 2025 11:31 AM To: Sparks, John Cc: R-help@r-project.org Subjec

[R] Using library(TTR) Calculate ATR by Symbol

Hi, In looking at the documentation for the TTR library and particularly the example for calculating the ATR (average true range). The example shows how to calculate ATR for a file of a single stock. If I have multiple stocks in one file, isn't there a way to get the ATR for each of them? Or
