tidyquant error downloading symbols for Index
Hi R Helpers, I recently tried to take advantage of the ability to download all the tickers in the S&P 500 using the functionality of tidyquant, but it threw an error. For summary, the set of commands that I ran was library(tidyquant) tq_index_options() tq_index("SP500") sessionInfo() R feedback including error message and sessionInfo are provided below. Guidance would be

Split charts with ggplot2, tidyquant
Hi Charlie, I am comfortable to put the data in any way that works best. Here are two possibilities: an xts and a data frame. library(quantmod) quantmod::getSymbols("SPY") # creates xts variable SPY SPYxts <- SPY[,c("SPY.Close","SPY.Volume")] SPYdf <- data.frame(Date=index(SPYxts),close=as.numeric(SPYxts$SPY.Close),

Error in axis ????
I did an update of both rstudio and my packages. I had some trouble but was able to move a lot of the packages so most troubles seem to be behind me. But having a problem with code that previously ran fine.

Quantmod, Xts, TTR and Postgresql
Hi Everyone, I'm currently using the latest build of R and R-Studio server (both are amazing products) I'm still very new to this but I came across this issue: I'm trying to do a select from postgres and put the data into and xts object like so: # Libs library('RPostgreSQL') # http://code.google.com/p/rpostgresql/ library('quantmod') library('TTR')

So the general strategy for getting these into separate panels in ggplot is to have a single variable that will be your response and a factor variable that indexes which original variable it came from. This can be accomplished in many ways, but the way I use is with the melt() function in the reshape2 package. For example, library(reshape2) plotDF <- melt(SPYdf, ??? ??? ??? ??? ??? ???

Split charts with ggplot2, tidyquant
Could you provide some information on your data structure (e.g., are the two time series in separate columns in the data)? The solution is fairly straightforward once you have the data in the right structure. And I do not think tidyquant is necessary for what you want.

Split charts with ggplot2, tidyquant
Hi Charlie, Thanks. This is helpful. As mentioned in my original question, I want to be able to plot a few such charts on the same page, say a 2 x 2 grid with such a chart for each of 4 different stocks. Using your solution I accomplished this by making a list pLst of your ggplots and then calling cowplot::plot_grid( plotlist=pLst, nrow=2, ncol=2 ) That worked fine. The one issue I have is that

For this kind of control you will probably need to move to base graphics and utilize the `fig` argument in par(), in which case you would want to run the plot() command twice: once with your first outcome and once with your second, changing the par() settings before each one to control the size.

Thanks for the reminder about lattice! I did some searching and there's a good example of manipulating the size of subplots using the `position` argument (see pp. 202-203 in the Trellis Users Guide: http://ml.stat.purdue.edu/stat695t/writings/Trellis.User.pdf). This is not within the paneling environment with the headers like in other trellis plots though, so you'll have to do a bit

That (the need for base graphics) is false. It certainly **can** be done in base graphics -- see ?layout for a perhaps more straightforward way to do it along the lines you suggest. However both lattice and ggplot are based on grid graphics, which has a similar but slightly more flexible ?grid.layout function which would allow one to size and place subsequent ggplot or lattice graphs in an

How to use getSymbols() to get annual data
Dear Sir/Madam, How to use getSymbols() to get annual data? For example, I need the annual stock price of APPLE from the year 2000 to 2016. How to write the command? I only know how to get the daily data. It is: getSymbols("AAPL",from="2000-01-01",to="2016-12-31") Thank you very much. Have a good week! Best regards, Yingrui Liu [[alternative HTML

Using string to call/manipulate an object
I am using getSymbols function from quantmod package to get price data from internet. Currently I have: my.ticker <- "IBM" getSymbols(my.ticker,src="google") This creates an xts object named my.ticker which contains historical price data for IBM. How can I call and manipulating this xts object using my original string my.ticker? I want to do: colnames(my.ticker) <-

Accessing variables inside a namespace
Hello Group, I am trying to see if there is way to access data that is inside another namespace. For e.g. the addATR function in the quantmod package calculates the ATR using the TTR package and then plots it to the graph. Now since it has already calculated the info that I need, can I access that data which if I look at the function code is stored in a variable called "atr"

Problem with tq_mutate_xy() from the tidyquant package
I was able to reproduce the problem with this self-contained example. Maybe it could be reproduced with an even smaller one ... library(tidyquant) # Loads tidyverse, tidyquant, financial pkgs, xts/zoo library(xts) dtV <- as.Date("2017-01-01") + 1:100 locL <- list( foo=xts(rnorm(100), order.by=dtV), bar=xts(rnorm(100), order.by=dtV) ) fullXts <- do.call(merge,locL) smallXts

using "plot" with time series object - "axes = FALSE" option does not appear to work
Dear R-help, I am attempting to plot data using standard R plot utilities. The data was retrieved from FRED (St. Louis Federal Reserve) using the package quantmod. My question is NOT about quantmod. While I retrieve data using quantmod, I am not using its charting utility. I have been having success using the standard R "plot" utilities to this point with this type of data.
