Missing data fields in yahoofinacier

I am trying to retrieve some fields in yahoofinancier that should be available according to the documentation: https://www.r-bloggers.com/2022/11/introducing-yahoofinancer/

When I run the script below it returns values for high, low, volume, forward PE, 50 day average, and 200 day average
But it returns NULL values for beta, averageVolume, averageVolume10days

Can someone advise why these values return as NULL?

Thank you!

#-----------------sample script
#load the library
library(yahoofinancer)

#----------------------------------------

select ticker and date range

tickerSymbol <- 'aapl'
startDate <- '2023-11-01'
endDate <- '2023-12-21'
interval <- '1d'
#---------------------------------------

create ticker class

ticker <- Ticker$new(tickerSymbol)

build dataframe of stock history

df <- ticker$get_history(start = startDate, end = endDate, interval = interval)
df <- data.frame(df)

get desired stats

fwdPE <- ticker$quote$forwardPE
avgVol <- ticker$quote$averageVolume
avg10dVol <- ticker$quote$averageVolume10days
avg50d <- ticker$quote$fiftyDayAverage
avg200d <- ticker$quote$twoHundredDayAverage
beta <- ticker$quote$beta

New error message when I'm using yahoofinancer

Hello,
I am a regular user of the R package yahoofinancer. The last time I used it, in May, it worked perfecty.

But now in October, I had this issue:

y <- Ticker$new("GOOG")
y.yearly <- y$get_income_statement('annual')
Yahoo Finance API request failed
Status: 401
Type: Client error
Mesage:
Descript

Then, I updated the R package 'yahoofinancer' from github and I now get this message:

y <- Ticker$new("GOOG")
y.yearly <- y$get_income_statement('annual')
Error: attempt to apply non-function

Would it be possible that the get_income_statement() function does not work anymore because of changes in the yahoo API features?

Thanks a lot.

CRAN error

https://www.stats.ox.ac.uk/pub/bdr/donttest/yahoofinancer.out

Row mismatch

nz50 = Index$new('^NZ50')
nz = nz50$get_history(start = '2003-01-03', interval = '1d')

produces

Error in $<-.data.frame(*tmp*, adj_close, value = c(1954.9599609375, :
replacement has 5070 rows, data has 5191

nz50 = Ticker$new('^NZ50')
nz = nz50$get_history(start = '2003-01-03', interval = '1d')

produces

Error in data.frame(date = as_datetime(unlist(data$timestamp)), volume = unlist(indicators$volume), :
arguments imply differing number of rows: 5191, 5070

Incorrect package alias

From CRAN:

Dear maintainer,

You have file 'yahoofinancer/man/yahoofinancer.Rd' with
\docType{package}, likely intended as a package overview help file, but
without the appropriate PKGNAME-package \alias as per "Documenting
packages" in R-exts.

This seems to be the consequence of the breaking change

  Using @docType package no longer automatically adds a -package alias.
  Instead document _PACKAGE to get all the defaults for package
  documentation.

in roxygen2 7.0.0 (2019-11-12) having gone unnoticed, see
<https://github.com/r-lib/roxygen2/issues/1491>.

As explained in the issue, to get the desired PKGNAME-package \alias
back, you should either change to the new approach and document the new
special sentinel

  "_PACKAGE"

or manually add

  @aliases yahoofinancer-package

if remaining with the old approach.

Please fix in your master sources as appropriate, and submit a fixed
version of your package within the next few months.

Best,
-k

Lots of zeros abnormally obtained when downloading companies' financials

Hello,
I'm using the 'yahoofinancer' package to download quartely financials from yahoo. In the last few weeks, I have faced this issue:
I get 0 values for many financial metrics for the last available quarter. For example, when loading the 'alphabet' quarterly financials, I get 0s for variables such as 'total revenues' or 'net income' for quarter ending '2023-03-31', although non-zero values are displayed on yahoo.finance.com (https://finance.yahoo.com/quote/GOOG/financials?p=GOOG).

alphabet.financials <- Ticker$new("GOOG")$get_income_statement('quarter')
print(alphabet.financials[,c("end_date","total_revenue","ebit","net_income")])

A tibble: 4 × 4

end_date total_revenue ebit net_income

no internet connection using validate

I know and checked the I have internet connection when using R, but I still get a no internet connection when I use the function validate.
Ex: validate("AAPL") does not give my any result other then no internet connection.
