I am unable to download ffanalytics from github.
The first one ran successfully:
install.packages(c("devtools","rstudioapi"), dependencies=TRUE, repos=c("http://rstudio.org/_packages", "http://cran.rstudio.com"))
An error occurred while running second one:
devtools::install_github(repo = "FantasyFootballAnalytics/ffanalytics", build_vignettes = TRUE,checkBuilt=TRUE)
Following error is shown:
Error: .onLoad failed in loadNamespace() for 'pkgload', details:
call: loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]])
error: there is no package called ‘backports’
Please help me.
