similar to: quantmod getOptionChain Interpret List Label As Date

Package? The **names** of the top levels of your lists, "Mar.09.2018", "Mar.23.2018" certainly look like dates and if they are -- I have no idea what package/context is -- they certainly could be formatted as such. See e.g. "date-time" . There are also several package that provide date tools. Cheers, Bert Bert Gunter "The trouble with having an open mind is

Hi R Helpers, Is it possible to interpret the top level of the list as a date after downloading all the option chain data for a ticker? For example, after I run aapl_total<-getOptionChain("AAPL", NULL) the top descriptor of the lists is a date (Mar.09.2018, Mar.23.2018, etc.). So if want to subset down to those parts of the list that correspond to say, (expiration)

Package? Quantmod. In the subject line. I agree that they look like dates, I don't know how to determine if they are actually dates. Josh Ulrich usually answers questions along these lines very informatively and quickly. One reasonable course of action is to wait to see if he does the same with this one. --JJS ________________________________ From: Bert Gunter <bgunter.4567 at

Hi Dirk, Thanks for your note. I understand that expiry dates are the dates that the option expires, so I don't think that I am confused about that (although the upper limits of one's confusion is difficult to accurately estimate). My lack of clarity come from treating those "dates" as actual dates as opposed to strings, which one could reasonably interpret them to be from

You know options but you are confused about maturity dates, i.e. expiry? In information in that list (ie along the date dimension) is the expiry; at each date you have another list for both puts and calls, and inside each of those a grid given by the

Dear R Helpers, I am still having trouble with the getOptionChain command in quantmod. I have the latest version of quantmod, etc. so I was under the impression that the problem was solved with updates to the package. If someone could let me know what I need to install in order to make this work, I would really appreciate it. My error message as session info are shown below. Thanks a bunch.

This script below pulls yahoo data via a function in quantmod, then massages the data around to forumalate a 3D graph with RGL library, attached is a ggplot to show the data i'm trying to create a surface with in separate line geoms . the issue is that the 3D graph looks very ugly and cut up because of the limited quantities of points on the front month expirations.. can anyone tell me whats

Hello, I am hoping someone can help tackle the problem below, for which I require a fast solution. It feels like there should be an elegant approach, but I am drawing blanks.

I've been looking for how to change a certain percentage of values in a data frame, but I've been struggling to find information in R. For example: #################example data############## > data V1 V2 V3 V4 V5 V6 V7 1 chr1 500 500 CHH 0 0.5 + 2 chr1 550 550 CHH 0 0.0 + 3 chr2 700 700 CHH 0 0.0 + 4 chr2 1000 1000 CHH 0 0.0 + 5 chr3

Hi, I'm new to R and Quantmod. I'm trying to make use of Quantmod's features however I'm failing at the first hurdle and I'm finding most R documentation a little cryptic. I have some minutely data for the same day for a stock in an existing timeSeries (ts) object. For example: Date time price volume 2012-03-12 08:01 45.01 10000 2012-03-12 08:02

OpCl works on xts objects but not on quantmod.OHLC objects. Is this a bug?

Hi all, I would need to put datas downloaded with quantmod into a matrix or a data frame. Suppose to start from here: *require(quantmod) ticker.list <- c('AAA', 'ALTSALES', 'AMBNS', 'AMBSL', 'BAA', 'EMRATIO', 'FEDFUNDS', 'GASPRICE', 'GS1', 'GS10', 'GS20', 'LNS14100000', 'MORTG',
