            QUESTION

            Is there a new solution for downloading package and dependencies for a given R version
            Asked 2022-Feb-09 at 03:33

            I have seen the question asked here from 2018. I'm wondering if there is a better answer today.

            Our work computers are bedeviled by an entire IT security department that seems to exist to make them useless. We are allowed to run R 3.6.3 (4.x hasn't been approved yet). We cannot connect to CRAN from behind the corporate firewall. In the past that meant we took our laptops home to install packages. But now we have a download monitor that blocks CRAN downloads even when we're on our own wi-fi.

            I was attempting to get around this by downloading the package .zip files on a personal machine, transferring them via CD, and then installing with repos=NULL. I used this code

            I'm not sure if it completely addresses your needs, but package checkpoint seems appropriate here. It allows you to download source packages from a snapshot of CRAN taken at a specified date, going back to 2014-09-17. R 4.0.0 was released around 2020-04-24, so the snapshot from 2020-04-01 should work for your purposes.

            How to change color of moving averages in ggplot, plotting two series into one graph?
            Asked 2022-Jan-27 at 19:32

            In order to highlight the moving average in my ggplot visualization, I want to give it a different color (in this case grey or black for both MA lines). When it comes to to a graph representing two time series, I struggle to find the best solution. Maybe I need to take a different approach.

            I think you can get what you want by not mapping variable to color in aes() for the MA part. I instead include group = variable to tell ggplot2 that the two MA's should be separate series, but no difference in their color based on that.

            R code runs well on one computer but not on another (via Task Scheduler in RScript.exe)
            Asked 2022-Jan-14 at 20:17

But when I run the same code on another machine in RScript.exe via Task Scheduler, it doesn't run. Another machine (machine 2) is able to send emails (when only the code for email is run), so I think the issue is with the following part.

            Whenever you schedule jobs, consider using a command line shell such as PowerShell or Bash to handle the automation steps, capture, and log errors and messages. Rscript fails on the second machine for some unknown reason which you cannot determine since you do not receive any error messages from console using TaskScheduler.

            Therefore, consider PowerShell to run all needed Rscript.exe calls and other commands and capture all errors to date-stamped log file. Below script redirects all console output to a .log file with messages. When Rscript command fails, the log will dump error or any console output (i.e., head, tail) below it. Regularly check logs after scheduled jobs.

            PowerShell script (save as .ps1 file)

            Asked 2022-Jan-01 at 06:13

            I am plotting the donchian high and low using tidy packages. the low value does not look correct. I am probably not calling the donchian function properly as the donchian_100_low is the highest value of the row. I dont know how to fix it.

            ANSWER

            Answered 2021-Dec-31 at 09:44

            The problem is the input into DonchianChannel. The input needs to be a matrix of 2 columns, not 2 separate columns. If you check the help it says:

            Object that is coercible to xts or matrix and contains High-Low prices.

            But it is a bit unclear. The example with it shows it a bit better, either a data.frame, matrix or xts object is fine.

            Note that if you want a donchian channel with n = 100, you need to specify the n, default is: n = 10.

            There are some mistakes in the Yahoo finance historical price for the Brazilian stock "PFRM3.SA". I was trying to conditionally change a value using dplyr. I managed to do it using case_when() but I couldn't make it work using replace(), which I think should be a more efficient solution.

            ANSWER

            Answered 2021-Dec-30 at 08:57

            You just need to add in rowwise before replace. Essentially, in your replace statement, close/100 is returning a new calculated value for every row. When in reality, you only want to replace the values greater than 100. So, with using rowwise, then it will only calculate per row, rather than for the whole cost column for the values parameter.

            Pagination getting cut off when adding download handler in flexdashboard
            Asked 2021-Dec-15 at 19:23

            I'm having an issue with the download handler from shiny (downloadHandler) and rendering a table using DT (using renderDataTable). When I use the download handler and render the table in my flexdashboard application, the pagination gets cut off. Thus, the user cannot switch to different pages of the table as the pagination doesn't fit the container or "the box" that renders the table. This only happens when I include the downloadHandler. If I include buttons using the extension from DT, the pagination does not get cut off. The problem is that I need to use the downloadHandler as the amount of data in my application is quite large. Please note, the example data is not representative of the size of the data. Does anyone know how to fix this issue?

            Using function on the whole list of XTS objects
            Asked 2021-Dec-14 at 18:17

            I'm trying to analyze candlestick formation Marubozu in R. So far I was able to download the different stocks data and find the formation using "Candlesticks" library in one stock data. I would like to automate that process so that I can run the CSPMarubozu function on many stocks at the same time.

            My main problem is that I cannot really understand how can I pass the list of data to this function. While trying to do it with for loop (Try 1) I get following error: "Error in CSPMarubozu((names(stocks_list[i])), n = 20, ATRFactor = 0.8, : Price series must contain Open, High, Low and Close." I know, that I can't pass the character variable to this function, but I can't find the way to get index names without the "" mark. (ex. "AMZN" and I need just AMZN"

            My other try (Try 2) was to do it with lapply() function but the same problem occurs

            This downloads stocks and then shows three different equivalent ways of processing each stock. We use dim(...) but that would be replaced with whatever processing is desired. Note that if x is an xts object for a stock having OHLC as well as adjusted close and volume then Op(x), Hi(x), Lo(x), Cl(x), Ad(x) and Vo(x) are the vectors of Open, High, Low, Close, Adjusted Close and Volume.

            Although the code below seems preferable getSymbols(stocks); L <- mget(stocks) also works to put the stocks loose into your workspace and then collect them into a list L.

            The link I provided in the comment above provides the answer you need. You just didn't implement it correctly. To specify a default for a selectInput with multiple=TRUE, you need to provide a vector of default values, not a scalar.
