The current release is available on CRAN, which you can install via:
install.packages("quantmod")To install the development version, you need to clone the repository and build from source, or run one of:
# lightweight
remotes::install_github("joshuaulrich/quantmod")
# or
devtools::install_github("joshuaulrich/quantmod")You may need tools to compile C, C++, or Fortran code. See the relevant appendix in the R Installation and Administration manual for your operating system:
It is possible to import data from a variety of sources with one quantmod
function: getSymbols(). For example:
> getSymbols("AAPL", src = "yahoo") # from yahoo finance
[1] "AAPL"
> getSymbols("DEXJPUS", src = "FRED") # FX rates from FRED
[1] "DEXJPUS"Once you've imported the data, you can use chartSeries() to visualize it and
even add technical indicators from the TTR
package:
> getSymbols("AAPL")
[1] "AAPL"
> chartSeries(AAPL)
> addMACD()
> addBBands()Ask your question on Stack Overflow or the R-SIG-Finance mailing list (you must subscribe to post).
