I\'m trying to use the quantstrat
package in R. I have uploaded/installed the package using
install.packages(\"quantstrat\", repos=\"http://R-Forge
I am very late here, but perhaps relevant to note that "blotter" and "quantstrat" are not on CRAN, and several years ago moved to GitHub. The README on the repo (https://github.com/braverock/quantstrat) has more information for installing blotter and more importantly quantstrat.
install.packages("devtools") # if not installed
install.packages("FinancialInstrument") #if not installed
install.packages("PerformanceAnalytics") #if not installed
# next install blotter from GitHub
devtools::install_github("braverock/blotter")
# next install quantstrat from GitHub
devtools::install_github("braverock/quantstrat")
